The Ergocube Good Posture 400 Ergonomic task chair with headrest, has a full spectrum of ergonomic features to ensure that it can fulfil each individuals requirements.

The GP400 petite ergonomic office chair, with high back is uniquely designed with a smaller seat pan, and a high contoured ergonomic back shape, with built in inflatable lumbar, and ratchet back height adjustment allows the user to create the best support, whilst being in a seated position.

The small seat pan, has memory foam, to allow the user more comfort, and takes more pressure for the lower area of the back.

The seat slide feature, allows the chair to have an increased sitting depth, to allow longer leg users a better support.

The adjustable seat angle, allows the user to change the seat angle, allowing them to open the pelvis, increasing the angle of the hips to knees, making them higher than the knees, and moving more pressure away from the lower back, and hips

Height, width and sliding arms, allows the user to sit up correctly in the Ergocube GP400 ergonomic office chair, giving the user, the option of support for use with the mouse, and keyboard. Whist sitting properly, and using the arms, the chair will give support to the back, hips, and upper back, and neck.

The tension control can be adjusted, to control the back angle variation, depending on users weight, and strength, to sit in the open, moving position, making the core work, and increasing blood flow, making the user feel, much more comfortable, and supported.
