The Extreme is an excellent mid-range general use cushion suitable for multiple uses in the home, office and vehicle. Measuring approximately 17.5" x 15.5" x 2" it comes in a washable fabric cover with a built in carry handle. Made in the USA from 100% Wondergel, which is the most advanced cushioning material available today. Made from an ultra-modern co-polymer, Wondergel provides comfortable support while eliminating pressure points. This lets you sit hours longer in comfort.
Long-lasting and highly durable Wondergel will never take a compression set, which means it will never lose its softness, its support, go flat or indent. Tested over many years of continual use this cushion will last for years.
