Our Chair Sizing Guide

“The chair has transformed my daily comfort.
Exceptional quality and service”

How We Help You Find the Perfect Fit

Whether it's reading, watching television, or simply relaxing at home, we spend a significant portion of our lives sitting down. Yet how many of us are actually sitting in a chair that truly fits our body? The reality is that most standard chairs simply aren't designed for individual comfort and support and over time, this can lead to poor posture and discomfort.

At Channel Healthcare we believe that everyone deserves to experience the benefits of a correctly fitted chair. With many years experience working alongside Occupational Therapists, we've seen first hand how the right chair can dramatically improve quality of life, providing not just comfort but essential postural support while helping maintain independence.

The secret lies in understanding that one size definitely doesn't fit all. From seat height and width to back support and arm positioning, every measurement plays a crucial role in how your body is supported throughout the day. In this guide, we'll walk you through the key components of bespoke chair sizing and explain why getting these measurements right can make all the difference to your comfort, wellbeing, and long-term health.

Because you shouldn't have to compromise between comfort and style - you deserve both.

Why is sizing so important?

From the height and width of your seats to how high the arms are, there are a number of key seating components that work in unison to ensure a chair is the perfect fit. We’ve listed these below:

Seat Height

The correct seat height will aid standing and should be in proportion to the lower leg length. Typically we look for a 90 degree bend at the knee and feet flat on the floor.  We would also need to confirm if you would usually wear footwear whilst seated.

We offer seat heights from just 10″ and can go as high as you need!

Seat Width

A correct seat width should allow for hip support and stability which will aid in comfort and also fatigue management. A chair with a seat width too wide can encourage leaning to one side which has a negative effect on the spine. When undertaking a chair assessment for you, we also take into consideration any changes in weight and types of clothing being worn.

Our chairs can be made with seat widths from 14″ – 34″

Seat Depth

The correct seat depth will eliminate the need for any additional cushions or pillows, the vast majority of chairs within the UK have a longer seat length than required which causes our bodies to sit in a slumped posture which can create long term problems.

If you're reading this while seated, check if you can sit with your bottom touching the backrest of the chair without any pressure on the back of your legs?

Back Height

The correct backrest height and design will allow for your head and back to be supported whilst complimenting your unique body shape and posture. Particular attention should be given to head support when in a reclined position as we often under-estimate the weight of the human head which can put strain on the upper spine and neck.

Does your current chair provide you with the correct level of head support?

Arm height

The correct height will allow for your arms and elbows to naturally rest on top of the armrest without lifting your shoulders or encourage leaning to either side.

The correct arm height also plays a vital part in giving a base of support when standing from a chair.

Weight Limit

It's often a taboo subject to ask a person's weight but we want to ensure each chair we provide has a suitable weight limit for many years of use. Our best selling chairs come with a 25 stone weight limit but we also provide chairs with weight limits up to a maximum of 70 stone.

If you are unsure of your weight don’t worry we have many years of experience and can ensure we find a solution that meets your needs.
