Your Essential Specialist Seating Checklist

There are 10 key chair checks to conduct for patients in order to get the maximum postural support and clinical benefits from a specialist chair.  The individual should be assessed by a Seating Specialist and this may or may not be conducted in conjunction with a clinician such as an OT or PT.  The recommended chair should be adjusted to meet the patient’s individual postural and pressure care needs; do not accept a ‘one size fits all’ solution as each patient will require features and functions to suit their individual needs and requirements.


Ensure each of the following 10 essential functions are accommodated by your chosen seating to achieve best clinical results as proven in our 2-year clinical research study.  We carried out a randomised control trial across multiple healthcare facilities in Northern Ireland from which we devised evidence based, best practice tips for providing Seating Assessments in order to achieve transformation results similar to those we experienced as a result of the research study. 

Some of the most significant results from the research study included:

  • A reduction in pressure ulcers.
  • A 56% reduction in the use of restraint.
  • An 80% reduction in the use of high cost pressure cushions.

  1. Load the BodyCS3_Ben_Phoenix_A cropped.jpg

Ensure the body is fully loaded and that every part of the body is in contact with the chair to redistribute pressure away from areas that are at risk of redness and pressure injuries.  Think about loading of the head, trunk, legs, arms and feet of the patient in the chair. 

  1. Support the Pelvis

When assessing seating and positioning you should always start with the pelvis, as the pelvis provides the base of support for the client sitting in the chair.  

Top Tip:  The width of your hand should fit easily between the patient and the side of the chair. If the chair is too wide it will encourage a pelvic obliquity.


The Importance of Pelvic Positioning.

If the pelvis is tilted then this will encourage the person to fall either laterally resulting in a pelvic obliquity:

or backwards resulting in a posterior pelvic tilt:

By supporting the pelvis the client is less likely to slide or fall.

The Seating Matters Phoenix™ and Sorrento™ have adjustable seat widths to accommodate changing user dimensions or various users in a multi-user environment.  Various seat widths are available on all chairs and padded arm covers can also be used to vary seat width.

  1. Support the FemursAtlanta Seat Angle Gif.gif

When seating a patient you must ensure the seat depth is adjusted to adequately load the thigh.

Top Tip:  Leave the width of two fingers between the edge of the seat and the back of the leg.

If the seat depth is too long it encourages sliding, resulting in a posterior pelvic tilt.  If the seat depth is too short the legs will not be fully loaded, which will result in increased pressure going through other parts of the body.

All Seating Matters chairs have seat depth adjustability.  In addition the Atlanta™ and Monaco™ chairs have a ramped seat to reduce the risk of sliding.

  1. Load the Feetfootplate image.png

The feet take 19% of the body weight so it is imperative that they are fully supported.

Loading the feet reduces sliding, provides proprioceptive feedback and encourages even weight distribution.

A footplate is essential and is therefore standard on all Seating Matters chairs.

The footplate on the Seating Matters Phoenix™ and Sorrento™ is height and angle adjustable.

  1. Support the TrunkPostural Support in Seating by Seating Matters.jpg

As far as possible try to ensure the patient in the chair maintains a midline postural position. If the client has flexible or partially flexible posture it may be possible to correct or partially correct their posture.  If the client has fixed posture then their posture must be accommodated in the chair.

This can be achieved by the use of lateral supports or by using the armrests to maintain or attain a midline position.  There are a variety of accessories available on the Seating Matters chairs to support and meet the needs of varying postures.  E.g. waterfall back, fibrelux back, lateral supports, triangular wedge, padded arm covers etc.


  1. Support the HeadDominic-Davis-Facebook-1.jpg

Correct positioning of the head is vital for aiding effective respiration, swallowing and communication.

Where possible the patient’s head should be balanced and aligned above the hips. If head control is absent or poor this can be achieved by the use of head supports and pillows.

The Seating Matters Phoenix supports the most complex upper body and head positions with its height adjustable back and integral head and shoulder supports.

There are a variety of accessories available on the Seating Matters chairs to meet the needs of varying head positions, such as a horseshoe pillow, a concave pillow and a standard head pillow.

  1. Support the ArmsCS1_Valerie_Sorrento_B-1024x1024.jpg

Although the arms only take 3% of the body weight, supporting the arms is essential to encouraging a midline position and to increase functional independence.

Ensure the arms of the chair are at the correct height and are fitted closed to the trunk to support a midline posture.  The arms of a chair help to provide lateral support and stability and without this support patients may use their arms to ‘fix’ themselves in their chair to provide the stability they need.  This reduces the ability for them to use their arms for functional tasks and therefore limits their independence.

The arms on the Seating Matters Phoenix and Sorrento are width adjustable and height adjustable.

  1. Use of Tilt in Spacetilt_in_space.gif

Tilt in space should be used to facilitate a change of position and pressure redistribution in patients with limited or no mobility. 

Tilt may also be used to alleviate kyphotic/flexed postures and is helpful in providing a comfortable position for resting when fatigue sets in.  

Tilt in space is important as regular weight redistribution limits pressure on the weight bearing areas such as the sacrum and IT’s.  It can facilitate improved posture, visual field, respiration, swallowing and comfort.

30 degree tilt in space facilitates a good functional position, which improves the clients’ ability to breathe, swallow and communicate.

If the client has a history of pressure injuries or at high risk of developing them, then the use of 45 degree tilt is advised to effectively manage this high pressure risk.

The NICE Guidelines state that clients require 2 hourly weight shifts when sitting continuously.  This can be achieved by the use of tilt in space.

The Seating Matters Phoenix and Sorrento are the only chairs available with 45 degree angle tilt in space as an option.


  1. Accommodate Tight HamstringsNegative Angle Footplate and Leg Rest Seating Matters.jpg

Tight hamstrings are commonly overlooked in seating and are a major cause of why patients might be sliding from a chair, which contributes to the risk of pressure ulcer development.

Always check hamstring range and set the leg rest to accommodate tight hamstrings.

Do not elevate the leg rest if hamstrings are tight.

All the Seating Matters chairs are designed to accommodate tight hamstrings.  A negative angle calf pad is available on The Seating Matters Phoenix™ and Sorrento™ to accommodate contractures.

  1. Appropriate CushionCushion-1.jpg

All Seating Matters chairs use Dartex, a multi-stretch breathable material, on all patient contact surfaces as standard.  All patient contact surfaces should allow for immersion and envelopment as this will facilitate maximum pressure management in seating, Dartex achieves this.  The cushion is removable to allow a patient to use an alternative cushion which they may have had previous success with if they so wish.  Please ensure the chair is adjusted to accommodate the new dimensions ensuring the body is full loaded in the chair.  Where possible ensure that there is nothing between the patient and the cushion.  The use of slings or incontinence pads will prevent immersion into the cushion and increase the risk of shear and friction.
