Permanent Coccyx Cut-out

Status is not alone in offering the option of a “coccyx cut-out” for chair seat pads, but in 2015 we reviewed the suitability of our version of this option and looked at how a new construction might offer greater benefit for sufferers of sacral or coccyx pain.

For many years we had, like many of our competitors, physically cut out a hole in the rear of the seat. The seat pad therefore had a distinctive physical appearance. Some users advised us that this helped with ensuring that their personal chair could easily be identified, but others felt that this also stigmatised their workplace. Facility Managers also felt that it might lead to a “spare” chair if the designated user switched location or employer.

In order to ensure that there was a good finish to the seat pad Status also had to create a stitching trim around the cut-out section. There were also comments from users with very sensitive backs that they could feel this stitching when they sat down. Often the users might also mention that they  found the seat pad to be hard.

The standard Status Humanfactor seat pad consists of 5 layers:

  • A shaped, ply seat pan with upward pelvic support and downward waterfall front
  • A high density foam chevron branded as Probax® and designed to encourage an upright posture and a slight forward tilt, bonded to…..
  • A central core of standard CMHR foam of a density that allows good weight displacement in accordance with the size of the seat, bonded to…..
  • A layer of Vasco® memory foam for comfort.
  • The selected fabric

We realised that cutting out a shape in the ply and foam was a necessary requirement for a coccyx cut-out, but we somehow had to find a way of avoiding the stitching and creating more comfort.

Our solution since July 2015 has been to construct the seat pad as follows:

  • A cut out of the ply and standard seat pad foam combination
  • An extra layer Vasco® memory foam covering the whole surface of the seat pad
  • A layer of fabric covering the whole seat pad.

This solution gives us many advantages:

  1. Optically, the seat pad looks like any other
  2. On sitting, the rear of the pad gives way and compresses into the gap in the same way that a historical coccyx seat pad would. Additionally, the spine is not squashed into a hole, but gently supported by the additional memory foam
  3. The extra layer of memory foam gives a softer feel across the whole human interface of the user’s lower body and rear thigh – important for users that are mentally and physically expectant of nerve pain.
  4. By combining the seat pad with the Therapod™ or Cpod® backrest systems a sensitive combination of seat and back support can be realised.
