bottom out if a more resilient foam layer was not underneath. The Nimblepedic Seat Wedge has memory foam is very dense with a high deflection factor capable of supporting users up to 300 lbs. The extreme temperature reactivity allows complete conformation to the shape of a person's bottom. The resultant pressure point reduction is amazing. Additionally, pressure on the tailbone (coccyx) is completely eliminated by a cutout in the area that your tailbone would rest. This thoroughly removes even minimal contact with a hyper-sensitive tailbone or hemmorhoidal tissues. In seated posture, the weight bearing surfaces of our buttocks are intended to be our ischial tuberosities of the pelvis and healthy seating should not apply pressure to the tailbone. Thus the cutout is imperceivable to the user. Please note that although the large wedge offered does indeed have the cutout, it is covered by fabric in this model.
This foam is similar to what was originally developed for seating in the N.A.S.A. space program. However, our memory foam has taken the process a step further for the purposes of this product. It has the amazing ability to slowly mold to each individual without bottoming out and without compromising support.
The Seat Wedges are available in two sizes:
The Large ( 14" x 18" x 3" ) with cut-out in foam but not in the cover and convenient carry handle (shown below), and the Small
( 12" x 16" x 3" ) with cut-out tailbone area and convenient carry handle (shown at top of page).
