New! This extra-large seat cushion is constructed of a highly resilient, furniture-graded foam with a layer of high density memory foam on top. This unique design combines the two key elements you are looking for: comfort and durability. Its extra size enables it to provide bigger coverage to dissipate pressure more effectively while conforming to body contours. It is firm enough to give you good support but not to the point of being 'too hard' to undermine its use as a cushion. It can be used in the car, home, or office. It is designed to help relieve back pain, numb buttocks, and other discomfort associated with prolonged sitting. What you get is a high quality product for a lot less than what you have to pay at specialty stores.
Extra-Large TravelMate Seat Cushion (Size: 19" x 17" x 3". Color: Black)
BREATHABLE MEMORY FOAM: Our extra-large cushion is covered with a layer of 3D ventilated fabric to disperse heat over a thick layer of premium memory foam, so you won’t experience heat buildup even after hours of sitting.
WON’T FLATTEN OUT: Give the TravelMate Extra-Large about a week to conform to your shape, and you’ll experience custom-fitting comfort every time you sit on it without the eventual flattening effects of inferior memory foam cushions.
NON-SLIP COVER: There’s nothing worse than your chair cushion sliding around, so we’ve added a non-slip silicone layer at the bottom of our extra-large cushions to keep them in place. We’ve even tested its non-slip abilities on a smooth marble floor!
RELIEVES BACK PAIN: Firm enough to support you and soft enough to be comfortable, TravelMate will support your whole body while sitting. It comes with a convenient carrying handle attached so you can take the comfort and support anywhere.
