Cover
Soft and Comfy Cover: Soft to touch and breathable to keep you cool and comfortable.
Quilted Cool Cover A breathable poly-blend cover featuring heat-wicking, cooling technology. The cover will provide a cool-to-the-touch or cooling sensation upon direct contact this is because the polyethylene fibers help to quickly disperse or wick away any superficial heat transferred to it through touch. A Shift-Resistant Lower Cover keeps your mattress in place and the layers inside in place.

Ergonomic Handles
Comfort
Siena means comfort. Comfort that helps you forget about the worries of the day. Comfort that tells your body, “relax, it’s time to recharge”. Comfort that helps you enjoy a long, deep, and soul nourishing sleep.
A sleep-tech-infused, cool-to-the-touch quilted breathable cover combines with gel-infused memory foam to help keep your sleeping temp regulated.
Support
Some people love super soft mattresses. Some people love a rock hard one. Most people are somewhere in the middle. That’s why the Siena is a medium firm mattress, comfortable to sleep on, but also firm enough to correctly support your body.
Move around freely without waking your partner or spilling your drink. Gel-infused memory foam gently cradles you to sleep and keeps you there, with a snug-as-a-bug body hug. Nectar's adaptive memory foam layer helps relieve pressure points beneath your shoulders, hips and legs, encouraging better spinal alignment. Because truly relaxed muscles are the key to deeper dreaming. The 3 inches of cushy high-density, pressure-relieving gel memory foam used in the comfort layer cuddles every joint and curve. Get tailored bounce-back with 2 inches of dynamically adjusting foam from the transition layer. Get the support your body needs to relax into a deep sleep. A sturdy 7-inch layer of standard foam ensures the comfort and support layers above it perform at their best.
