Quick Summary

Nighslee offers the Cool Gel Memory Foam Mattress. As the name implies, this bed features a comfort layer of ventilated, gel-infused memory foam. It also has a transitional layer of bamboo-infused polyfoam and a high-density polyfoam support core; the cover is made of rayon derived from bamboo. The Cool Gel Memory Foam Mattress is 10″ thick and considered ‘Medium’ in terms of firmness, or a 5.5 on the 1-10 firmness scale.

Temperature neutrality is a major strength of the Cool Gel Memory Foam Mattress. The ventilated, gel-infused top layer, bamboo-infused transitional layer, and breathable cover help regulate the temperature of the entire bed. As a result, it sleeps cooler than many all-foam competitors. The mattress also conforms very closely without excessive sagging, making it optimal for sleepers – side and back sleepers in particular – who weigh between 130 and 230 pounds, as well as lighter or heavier individuals who prefer moderate firmness. Other advantages of the Cool Gel Memory Foam Mattress include great motion isolation, no noise when bearing weight, and an exceptionally light frame that is easy to lift and move for most.

Current price-points for the Cool Gel Memory Foam Mattress are significantly lower than those of the average memory foam model. Nighslee also offers free shipping within the contiguous U.S., and backs the product with a 100-night sleep trial and 10-year warranty.

Read on to learn more about how the Cool Gel Memory Foam Mattress is constructed, priced, and shipped. We’ll also provide an overview of Nighslee’s return and warranty policies, as well as other products available from the company.
