How to unpack and assemble the seating system

Check parts

Congratulations on purchasing your Mygo

Seating System. All of the parts will be contained in polythene bags with each one clearly labelled. Carefully remove them from the boxes and check all the parts you have ordered.

Safety First

Keep polythene bags away from children.

Some of the accessories will need to be assembled before you attach the seat to the base you have purchased. If you are fitting the seat to a mobility base please ensure you fit the interface plate to the mobility base first. Instructions on how to attach the interface to specific bases will be provided with the interface plate. Once you have checked all the components you are then ready to assemble the Mygo Seating System and attach it to its base.

Multi-tool

A number of adjustments will require the use of the multi-tool, which is supplied with each seat and can be found in the back pack.

10.3 Hip Laterals (with

Pelvic Cradle only)

To set the width of the hip guides loosen the

Allen bolts (A), adjust to the desired width and retighten.

10.4 Backrest depth

The backrest depth is adjusted by depressing the popper then sliding the back support tube to the desired position. This is very important as it will ensure the seat will fit the child, both when they are upright and in a recline position.

There are three settings where the popper can be located.

We recommend that you measure the child’s upper leg length to define the required seat depth (SD). To do this measure from the child’s lower back to the back of their knee.

Then set the backrest to position A, B or C based on the table below.

This backrest depth should not be adjusted while the child is in the seating system.

10.5 Backrest height

The overall height of the backrest can be adjusted by loosening the two socket cap bolts, then positioning to the required shoulder height of the user. Once in position the socket cap bolts should be retightened securely. The height can be fine tuned when the user is in the seat.

Use caution when adjusting to minimum setting as fingers could become trapped between moving and static parts.

10.6 Backrest angle

The backrest can be angled by loosening the bolt (A). Select the position you require then retighten the bolt securely. Always ensure the back angle is secure to maintain the desired posture for the child.

The backrest angle can be adjusted with the child in the seat, but always support the backrest with one hand.

There are two angle indicator strips on either side of the back adjuster. We have supplied angle location markers (shown below) on a card. These can be applied to the clear strip on the adjuster tube to indicate the desired positions for various activities such as rest, feeding, play.

The angle indicator strip indicates the angle from the seat cushion to the backrest.

Always make sure the bolt is secure as this could cause injury to the child or carer.

The black and yellow hazard strip on the inner tube indicates the maximum forward or prone position the backrest can be adjusted to.

10.7 Adjusting the

Dynamic Backrest

To achieve the required amount of dynamic movement loosen the handle (a), slide to the required position and retighten securely.

To return the backrest to a static position, loosen the handle (a), slide the backrest strut to the bottom, retighten the handle.

To angle adjust the backrest where a dynamic backrest has been fitted, you use the handle at the base of the backrest. Pull the locking pin (c) and twist and unlock. Lift up the handle (b) and adjust the backrest.

Pull the locking pin (c). Ensure that the locking pin is secure.

The range of the backrest angle and the range if dynamic movement are a maximum of 30°, i.e. if the backrest is upright, a full

30° is available on the dynamic system. If the backrest angle is at 10° then only 20° of movement is available with the dynamic backrest and so on.

The backrest must be in the upright position with the dynamic function locked off (i.e. the handle to the lowest position on the backrest supine) and ensure the locking pin (c) is engaged when the seating system is used in transport.

10.8 Adjusting the upper leg supports

The upper leg supports will be set at the minimum position on arrival. Set the depth before placing the child in the seat.

Fine adjustment is possible afterwards but is restricted by the user’s weight. To achieve the correct position measure the length from the child’s lower back to the back of their knee.

For Size 1 adjust the supports to the desired position using the locking lever (A) underneath the seat base. To adjust, press the locking button and release. Keep the supports pointing straight forward at this time unless wind sweeping or adduction, abduction must be accommodated, in which case set the angle accordingly using the locking lever again.

The supports can be readjusted once the child has been placed in the chair.

For Size 2, loosen the locking levers under the seat and slide leg support to required position. Keep the supports pointing straight forward at this time unless wind sweeping or adduction, abduction must be accommodated, in which case set the angle accordingly. Retighten bolt. To increase the angle further, remove bolt and move leg angle to wider setting. Insert bolt into second slot (B) and tighten.

You may have to adjust the angle to achieve the required foot position. To adjust the angle loosen the bolt (B) with the multi-tool, set to the desired angle and retighten.

There is a safety popper to indicate maximum safe extension. This can be set with the child in the seat.

Always check the footplate is secure to prevent the user sliding forward and down in the seat which could pose a choking hazard if a chest or trunk harness is attached.

10.11 Footplate angle adjustment

To set the angle to accommodate plantarflexion or dorsiflexion, simply loosen or tighten the hand knob (A) to select the angle you require.

The footplates can simply flip up to aid transfer.

10.12 Flexible sacral support

10.13 Lateral supports

The flexible sacral support is used in conjunction with the pelvic positioning harness or Pelvic Cradle. To adjust the height, depth and angle, loosen the bolts on either side with the multi-tool provided.

Adjust the support to the correct angle then retighten the bolts. The support will flex back and forward to assist the child into the preferred posture.

Loosen the socket cap (A) to adjust the width, height and angle of the lateral supports and retighten when you have achieved the desired position.

To move flip away laterals, use knob B.

Always use caution to ensure fingers do not become trapped when adjusting the sacral support.

10.14 Chest harness 10.15 Trunk harness

To change the width of the chest harness. Lift the front cover, adjust the Velcro straps to the desired width and replace the cover.

When the child is out of the seating system the trunk harness will be open but remain attached by two side clips (A) on one side and one pelvic harness clip (B).

When placing the child in the seating system bring the trunk harness across the front and attach by connecting the clips into the buckles on the other side (C).

Connect the remaining straps into the pelvic harness or Pelvic Cradle by feeding them through the loop (D) and snapping into place.

Then connect the shoulder straps (E) into the clips at the top.

If your child is wearing outdoor clothing, the side straps can be opened by releasing the snap fasteners. The pelvic harness connecting strap can be released by moving the strap to the lower snap fastener position.

All the connecting straps are adjustable by lifting the cover, adjusting to the desired length and replacing the cover.

Check the laterals and harnesses regularly to ensure they have not become loose as without appropriate trunk support the child may be at risk of slipping into a position they cannot recover from. This could present a choking hazard.

10.16 Adjusting the knee pads

10.17 Sandals

The kneepads can be used as a limiter to help prevent the child from sliding forward in the seat. It can also be used above the knee to prevent the child from raising their foot. To adjust the knee pads lift the front cover adjust the Velcro straps to the desired length and reposition in place. To remove unclip the snap fastener on one side.

To position the user’s feet in the sandals secure the Velcro straps provided so the foot is held in place. The straps should be placed over the bridge of the foot and over the toes.

The front strap can be fed through one of two slots on either side of the sandals, depending on the size of the user’s feet (2).

Frequent adjustment for daily use

(therapists/ carers/parents)

Parents and carers should be shown how to make frequent adjustments and be made aware of the safety checks in Section

6 by a technically and clinically competent person who has been trained in the use of the product.

Leckey recommend that a written record is maintained of all parent and carers who have been trained in the use of this product.

11.1 Transferring your child into and out of the seat

Before transferring the child into the seat carry out the daily product inspection as outlined in section 13 of this user manual.

Adjust the seat to a comfortable height to facilitate transfer. Lock all the castors, ensuring that they are facing outwards to maximise product stability. Make sure the safety buckle on the chest harness is released and is out of the way to facilitate transfer.

If the seat has flip-away thoracic laterals, first move these out of the way using knob A.

Unclip the pelvic harness or Pelvic Cradle in the middle, undo the side velcro of the

Pelvic Cradle and allow the harness to open out to facilitate transfer. Lastly if sandals are fitted open the straps. You are now ready to transfer or hoist the child into the seat.

The pelvic harness and Pelvic Cradle are fastened using the middle buckle, and side velcro (in the case of the Pelvic Cradle).

Always secure the pelvic harness or

Pelvic Cradle first before fastening other buckles or harnesses. Adjust the harness so the child cannot slide or creep forward in the seat.

11.2 Adjusting the pelvic harness or Pelvic Cradle

The correct positioning and tensioning of the pelvic harness or Pelvic Cradle is key to a child’s postural management, affecting their comfort and ability to carry out activities.

Please consult with your therapist to ensure the harness is positioned correctly and that the straps are tensioned appropriately.

To tension the pelvic harness straps and pads around the child pull the centre strap

(A). Pull the two side straps up to fine tune the pelvic position and adjust (B) the height of the pads on the hips.

To tension the Pelvic Cradle use the 4 side straps (C) and the velcro tabs (D).

If using the seat outdoors and your child is wearing a coat, position the pelvic harness or

Pelvic Cradle under the coat.

Pelvic harness (Size 1 or Size 2) Pelvic Cradle (Size 2 only)

If the child is active or has extensor spasms check the Pelvic harness or

Pelvic Cradle is secure after each spasm to ensure the child is safe and cannot slide forward in the seat.

Always fasten the centre buckle on the pelvic harness or Pelvic Cradle before making any other adjustments.

11.3 Chassis 11.4 Powered height adjustment

The Mygo Seat is designed to fit onto a range of chassis. This user manual shows the correct and safe use of the seating system with the Leckey Hi-low chassis. For all other chassis or bases please refer to the manufacturer’s handbook.

To prepare the Hi-low chassis for the seating system we recommend that you raise the chassis to a comfortable working height by pressing the foot lever at the rear of the chassis or by pressing the up button on the handset of the powered option.

The powered chassis can be easily adjusted with the push button control handset. The seat can be height adjusted with the client in the chair. Before the product is used for the first time it is recommended that the battery should be fully charged for 12 hours. To do this plug the adaptor into the mains socket and attach the lead (A) to the battery and switch on the mains supply power. When charged switch off mains power, remove the adaptor plug and disconnect the lead from the battery. The battery charge should be topped up each day for approximately one hour. The chair can be adjusted in height while connected to the mains.

11.5 Height Adjustment

– Hi-low chassis

You can carry out this adjustment with the child in the chair. To adjust the height of the

Hi-low chassis press the foot lever at the rear of the chassis or press the up button on the handset of the powered option whilst holding the push handle. Once you remove your foot from the pedal or your thumb from the handset the seat will be fixed at the chosen height.

For safety the height adjustment pedal on the chassis can be locked by engaging the pull pin (C) on the right hand side of the pedal. To unlock pull the pin out and rotate

90 degrees, the pedal can then be operated.

The locking pin (C) should be kept in the locked position when you are not adjusting the chassis.

Always keep the locking pin engaged when you are not adjusting the chassis.

This will prevent the foot pedal being operated accidentally.

For children over the weight of 27kg

(60lbs), raising the manual chassis is a 2 person lift (UK lifting and handling regulations).

Always use caution as hands could become trapped when height adjusting the base.

11.6 Tilt in space

The tilt in space can be angled while the user is in the seat. Before you adjust the tilt in space angle of the seat always ensure the pelvic harness is secured preventing the user from sliding forward in the seat.

To adjust the tilt angle press the lever under the seat base. Once you have selected the angle you require, by simply removing your hand from the lever, the chair will be locked in position. The tilt in space should be locked off while the user is in the seat. To lock the lever twist the pull pin to the right hand side of the lever and the pin will pop into position. You may have to lift the lever slightly to allow it to lock. To unlock pull the pin out and rotate 90 degrees, the lever can then be operated.

Always keep the tilt in space lever in the locked position to prevent accidental actuation of the lever which could cause the seat unit to jolt and possibly cause injury to the child.

Please use handle bars when operating tilt in space.

Always check with your therapist that the use of tilt in space will not cause any obstructions to the child’s airways.

Locking pin

11.7 Adjusting the

Dynamic Backrest

To return the backrest to a static position, loosen the handle (a), slide the backrest strut to the bottom, retighten the handle.

11.8 Chest and Trunk

Harness adjustment

If the child requires chest support as part of their postural support programme the seat will be fitted with rigid laterals or a combination of laterals, chest harness and trunk harness. These may need to be adjusted on a daily basis to accommodate differences in clothing.

Always check with your therapist as to the optimum positioning and tensioning of the straps and support items for the child.

To change the width of the chest harness, lift the front cover, adjust the Velcro straps and set to the desired width. When the correct width has been achieved replace the cover.

Please refer to section 10 for specific guidance on adjusting the trunk harness.

Always make sure the plastic buckles are fully engaged when using the chest harness.

Check the harness and laterals are secure to ensure the child is safe and cannot slide forward in the seat as this may restrict their breathing.

11.9 Sandals 11.10 Tray adjustment

To position the user’s feet in the sandals secure the Velcro straps provided so the foot is held in place. The straps should be placed over the bridge of the foot and over the toes. The front strap can be fed through one of two slots on either side of the sandals, depending on the size of the user’s feet (2).

If the child is wearing sandals or light footwear check the straps to make sure the webbing does not irritate the skin.

The activity tray can be used for a range of functions and its position can be fine tuned to suit the user and the activity whether it is for fun, education or feeding. The tray is attached to the seat by inserting the tray tubes through the centre of the armrest.

Once the tray is located in the position the knob (A) should be tightened securely.

Adjust the armrests to set the height and angle of the tray.

11.11 Armrest adjustment

Always use caution as fingers could become trapped in the slot when adjusting the height.

Always use caution to ensure the child’s hands or arms do not become trapped when inserting the tray.

Never use the tray to steer or push the chair.

Do not place hot objects, greater than

40 degrees Celsius on the tray.

Please note that the tray is for the use of the user only. Do not lean or place heavy objects on the tray, not greater than 8kgs (17.6lbs).

To adjust the height of the armrest loosen the hand knob (B) set to the desired height and retighten. To adjust the angle rotate hand knob (A) until the desired position has been achieved.

To remove the armrest completely for side transfer or assist in getting the child into or out of the seat loosen hand knob (C), press popper (D) and lift the armrest.

11.12 Grab rail adjustment

To set the depth of the grab rail to suit the child’s reach loosen knob (A), adjust to the required depth and then re-tighten.

Do not adjust the horizontal bars beyond the mouldings, except when you are removing the tray.

To remove quickly, loosen knob (B) at either side and slide rail up vertically.

11.13 Frequent

Adjustments

To achieve the required amount of dynamic movement loosen the handle

(a), slide to the required position and retighten securely.

To return the backrest to a static position, loosen the handle (a), slide the backrest strut to the bottom, retighten the handle.

To angle adjust the backrest where a dynamic backrest has been fitted, you use the handle at the base of the backrest. Pull the locking pin (c) and twist and unlock. Lift up the handle

(b) and adjust the backrest. Pull the locking pin (c). Ensure that the locking pin is secure.

The range of the backrest angle and the range if dynamic movement are a maximum of 30 o

, i.e. if the backrest is upright, a full 30 o

is available on the dynamic system. If the backrest angle is at 10 o

then only 20 of movement is available with the dynamic backrest and so on.

The baqckrest must be in the upright position with the dynamic function locked off (i.e. the handle to the lowest position on the backrest supine) and ensure the locking pin (c) is engaged when the seating system is used in transport.

12 Cleaning & Care

Information

How to Maintain

When cleaning we recommend that you use only warm water and a non-abrasive detergent. Never use organic solvents or dry cleaning fluids.

Upholstery and fabrics

1. The cushion covers can be removed, machine washed at 40ºC and tumble dried at a low temperature.

Please remove the foam from the following covers before washing:

Headrest

Shoulder support

Backrest cushion

Seat base cushion

All other soft upholstery can be placed into the washing machine intact, after removing bolts and fastenings.

3. Staining should be removed as quickly as possible with absorbent cloth, towels or a sponge. Routine soap and warm water sponging is effective for ordinary soiling and minor spills. Be careful not to over wet the fabric as this will cause the staining to spread.

4 Antiseptic cleaning agents can be used on more stubborn stains. These may require a safe solvent such as Isopropyl Alcohol or

Mineral Spirit. A half cup of household bleach to 5 litres of water can also be used as a useful disinfectant.

5. The pelvic and trunk harnesses can be machine washed at 40 Deg C. Make sure all bolts and fasteners are removed first as they may cause damage to your washing machine. Store these in a safe place and out of reach from children.

6 Always ensure the product is dry before use.

Metal and plastic components

1. Soap and water or antibacterial spray can be used for daily cleaning.

2. For deep cleaning a low pressure steam cleaner can be used.

3. Do not use solvents to clean plastic or metal components.

4. Make sure the product is dry before use.

2. The upholstery and fabrics can also be cleaned by hand whilst in place. When cleaning we recommend that you use only warm water and a non-abrasive detergent.

13 Daily Product

Inspection

(Therapists, parents & carers)

We recommend that daily visual checks of the equipment are carried out by therapists, carers or parents to ensure the product is safe for use. The recommended daily checks are detailed below.

1. Check that there is no lateral movement or wobble in any of the moving parts. Ensure all adjustment knobs and bolts are in place and secure.

14 Annual Product

Inspection

(Therapist, Technician, Leckey Product

Advisor, Dealer)

Leckey recommend that each product should be subject to a detailed inspection at least once a year and every time the product is reissued for use. This inspection should be carried out by a technically competent person who has been trained in the use of the product and should include the following checks as a minimum requirement.

1. Check that there is no lateral movement or wobble in any of the moving parts. Ensure all adjustment knobs and bolts are in place and secure.

2. Check all ratchet handles, knobs, nuts, bolts and plastic buckles are in place, replacing any missing items. Paying particular attention to the following items;

> Headsupport locking bolts.

> Backrest height and angle

adjustments bolts.

> Seat depth adjustment bolts.

> Pelvic harness / hip guide

attachment bolts.
