Part of the luxurious Thomas Cole Sleep collection, the Eden Mattress is crafted by hand from start to finish in a WI partner mattress Factory. Providing cloud-like comfort and softness on the surface, this plush mattress features dual layers of high-density plush foam for personalized comfort that conforms to your body. And the quilted system gives sleepers a functional temperature-neutral sleep environment from the fabric cover on the top; a second layer below that of three-fourths ounce fiber; then sewn to high-density foam layers and a conformance layer of HD nano pocketed individual LUX-COMFORT coils. Deep down then a more supportive 2024 Zoned Center Support Pocket Coil upgraded innerspring. The middle third is now 7% heavier and therefore adds more ZONED CENTER SUPPORT. Plus, the support unit is an 8” pocket coil with 4 sided foam rail seat edge encasement. On a side note, every mattress in the Thomas Cole Sleep line is constructed to be adjustable base compatible and comes with an industry-leading 15-year non-prorated warranty.
