We studied the various coccyx cushions out there and after pouring through thousands of reviews went to the drawing board to come up with what we feel is the best Coccyx Cushion.

Our Ergo21 Coccyx Cushion was designed so that it can be used as Coccyx Cushion with a cut out at the tailbone; or simply rotate it and use it as a regular cushion. In either case the four LiquiCell Membranes remain around the tailbone and thighs.

Our Ergo21 Coccyx Cushion surely has the WOW factor and will put a smile on your face!

    • Comes in two sizes. Regular and Large. There are hardly any cushions out there that can accommodate individuals who are on the heavy side. This is a big plus. A small cushion cuts off circulation under the thighs.
    • We have added Liquicell Blood Flow Technology – Four liquid filled membrances – Two under the tail-bone and two under the thights to prevent sores and skin breakdown from vertical pressure. A video on our website explains the technology. This technology is also used in hospital beds for burn and stoke patients who cannot move. Also, a famous recliner maker is using it in recliners for Dialysis Patiens who have to sit long hours for treatment. You can also find a $6,000 Office Chair on Amazon with this technology.
    • Our cushions are made here in Los Angeles, USA. We use the High Resilience foam that retains the shape after repeated sittings for years to come. In addition a top fashion designer was inolved with the fabric selections and construction to make all our Cushions looks sleek, modern, and high end!
