CMHR (Combustion Modified High Resilient) foam is used when the strictest fire code standards are required, such as in hotel lobbies, hospitals, schools, mass transit (airplanes, buses). The foam has a high density which helps it last a long time. Fire retardant chemicals in the foam give the texture a grainy feel.
The H03 350 is the most luxurious model in the environmentally-friendly H03 series. It is medium-backed and fully upholstered for a seriously comfortable and supportive fit. It has inherited the backwards and forwards rocking mechanism that makes this series so popular. This means the back moves with the body to promote oxygen and blood-flow, which boosts concentration and energy levels. Because it promotes ‘active sitting’, the 350 is very popular in schools, colleges, Universities and other establishments where sitters have to concentrate for long periods of time.
This chair is fully ergonomic, with parts that can be easily adjusted to fit the unique contours of the sitter’s body. A well set-up office chair can help to reduce the risks of aches and pains in the shoulders and back.
Environmentally-conscious organisations will be pleased to hear that most of the chair is made from recycled bumpers and household goods.

Sometimes, over time, the gas stem can become a little stiff when trying to adjust the height. A quick and easy fix for this is using WD-40 or Vaseline. Apply a light layer of grease to the gas stem, then try adjusting the gas stem 3-4 times. The gas stem should now adjust easily.
The seat depth and back height are adjusted simultaneously in one grip. There is a tab on the left hand side of your H03 350. Pull this up and then adjust the two grips on each side of the chair to adjust both the back height and seat depth. Once you are comfortable, push the tab downwards to lock.
