Nature's Sleep
Cayman Gel Memory Foam Mattress

The Cayman Gel Memory Foam Mattress is one of four 12" high memory foam mattresses by bedding manufacturer Nature's Sleep. The other two are the Sapphire Gel Memory Foam Mattress, the Clacier Gel Memory Foam Mattress and the St. Cloud Memory Foam Mattress. It is also the closest model to the Nature's Sleep 12" Gel Memory-Foam Mattress listed on Groupon. Both are reviewed here with the differences in their descriptions noted.

Cutaway view of the Cayman

The Cayman has a 350-gram weight embroidered/embossed cover made of rayon (viscose) and polyester. This cover is zippered and can be removed and dry cleaned (Groupon mentions spot cleaning). It is "allergen resistant" which means that it resists dust mites, which carry allergens into mattresses, furniture, etc. The top panel of this cover is quilted to 1" of Nature's Sleep Next Generation visco memory foam. The bottom is anti-skid, keeping the mattress and the sheets in place.

The signature feature of this memory foam mattress is the gel-infused memory foam. Nature's Sleep calls this a Premium memory foam with Superior Gel Technology (SGT). The gel infused into the foam is described as "spheres" in contrast to other manufacturer's use of beads, which seems to imply that these are larger than the normal beads, or more regular in shape, or both. The Cayman has a 3" layer of SGT memory foam, while the model on Groupon has 2" Advanced Gel Technology memory foam topped by 1" of Advanced Visco Technology memory foam. In this respect, it appears that the model described by Nature's Sleep is an upgraded version of the model shown on Groupon. On the other hand, this could be an edition of the Cayman customized for Groupon (retailer customization is common among bedding manufactures).

The memory foams comform to the sleeper's body contours. Gel makes the memory foam more supportive and also "captures" heat and conducts it down and out for cooling.

The Cayman has an 8" highly dense polyurethane support core. This provides overall support for the entire mattress, including edge support for the sleeping surface. All foams in the Nature's Sleep Cayman Gel Memory Foam Mattress are certified by CertiPurUS as free from harmful substances A thin protective sheet, called a scrim, separates the support core from the comfort layers above.

The Nature's Sleep KD Foundation and three adjustable beds are sold by Nature's Sleep for use with their mattresses, including the Cayman Gel Memory Foam Mattress. The upholstered KD has a cloth-covered woven wood slat surface on a wood frame. Other foundations are compatible with the Cayman, including platform beds and European wood slats (if the slats are closly spaced). However, box springs (the traditional kind) are not recommended.

The Cayman is covered by a Nature's Sleep 20-year limted warranty. It and its equivalents are sold online by Nature's Sleep and through several authorized dealers.
