Frequent Adjustments for Daily Use
This page shows how to make some adjustments to the Mygo. They are the types of adjustments that may need to be done every day. Even though they do not involve clinical set up of the Mygo, Leckey still recommend that parents and carers should be shown how to make these frequent adjustments by a technically and clinically competent person who has been trained in the use of the product.
Transferring your child into and out of the seat
Before transferring the child into the seat carry out the daily product inspection.
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.
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.
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.

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.
Powered height adjustment
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.
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.
Tilt in space
Before using the tilt in space function, please check with your therapist that the use of tilt in space will not cause any obstructions to the child’s airways.
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.
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. To change the width of the trunk harness, adjust the straps A, B, C and D which attach the trunk harness to the seat.
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.
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.
If the child is wearing sandals or light footwear check the straps to make sure the webbing does not irritate the skin.
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.
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.
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).
Grab rail adjustment
To set the depth of the grab rail to suit thechild’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.
