The Tencel cover is fully quilted and embroidered with an aloe-vera derived gel-foam. This makes for a soft, fluffy top layer that also has cooling properties. The Tencel material ensures maximum breathability, while the foam quilting sucks heat and moisture away from the surface. This cover also assists in keeping the mattress free of bedbugs – so much so in fact, that the company will replace either the bed or the cover if it gets infested with bedbugs.

The quilting itself is a 1-inch layer of gel foam – a feature which many companies refuse to include due to the expensive, difficult nature of quilting and embroidering this layer.

The next layer is 1-inch of semi-open Lush Foam which is usually reserved for medical uses. This layer is also gel-infused, and absorbs heat and distributes it evenly throughout its surface. Additionally, this Lush Foam recovers rapidly from compression, and quickly returns to its natural state.

The middle core of the bed, and the layer which provides support, is the 3-inches of adaptive Hi Core memory foam. This layer gives contouring and support, and is so dense and heavy that it actually requires higher shipping costs for the manufacturer than most memory-foam mattresses. The Hi Core foam gives the bed some rebound and bounce, and allows the bed to take your shape while still keeping you stable and secure.

The final layer is 6-inches of breathable support foam that is specifically channelled to allow for maximum air circulation from all sides. This is a dense, thick layer that provides a base for the bed, meaning you can sleep on this mattress without a bed-frame.

The Nectar comes with a good selection of high-tech materials, arranged in a smart way. With the manufacturing taking place in China, these materials can be sold by Nectar Sleep at a fraction of the expected price. Overall, the Nectar comes up with the premium goods, and scores well here.
