The Ergo Sit high-back ergonomic office chair is much more than just an office chair. With back pain affecting 80% of Brits at one point in their life, it’s of paramount importance to look after your spine – especially for those of us with desk jobs.

This seat has been approved by a UK chiropractic doctor and is suitable for users between five feet and six feet six inches tall. The deeply padded seat gives excellent comfort and has a waterfall front giving soft comfort to the underside of the knees.

The backrest has a ratchet mechanism that is fully adjustable in height and is fitted with an adjustable pump lumbar to ensure contoured lumbar cushioning into the small of the back to suit each individual. This is able to be adjusted independently from the seat.

Onto this, we fit an ergonomic headrest that is height adjustable and tilts forward and back ensuring the correct neck and spinal support.

The height of the seat can be changed to suit you perfectly and give excellent posture support.

The design of this seat means that it is suitable for a 24-hour working environment while the heavy-duty gas strut is functional for up to 27 stones.

A five-legged base ensures stability while castors mean that the chair moves easily across almost any surface.

This British-made chair is covered with a 5-year guarantee.

Quick delivery, good quality chair not too bulky but feels substantial enough to last. Comfortable for office hours. Good for ergonomics. With working from home continuing it meant I needed an upgrade to support my back. Pleased with this purchase.

Never used them before. The web page was easy to navigate so I ordered from them and received the next day. Watched their video in setting up chair, easy to follow. Chair is really supportive and adjusts exactly to my requirements.
