Our take on the Sweetnight Coolnest 14 in. California King Medium Memory Foam Mattress

The Sweetnight Coolnest is a 14-inch medium-feel memory foam mattress in California King size, built with a gel-infused foam layer meant to sleep cooler than plain memory foam. The thick profile gives it a deep, cushioned feel that suits side and combination sleepers more than stomach sleepers who want a firm surface. It is a mattress only, so a box spring or slatted base is needed underneath. Against other bed-in-a-box foam mattresses, it stands out on thickness and weight capacity rather than on edge support or motion isolation at the top of the class.

Questions and answers

Does the Sweetnight Coolnest need a box spring?
Yes. It is a mattress only and is designed to sit on a box spring or a slatted base. A solid platform also works and gives firmer support.
Is the medium feel right for stomach sleepers?
Usually not. Stomach sleepers tend to want a firmer surface to keep the hips from sinking. Side and combination sleepers are the better fit.
Will it sleep cool?
The gel-infused foam is meant to pull heat away, but it is still a thick all-foam mattress. Hot sleepers may find it warmer than a hybrid with coils.
How long does it take to expand?
It ships compressed and rolled. Most of the loft returns within a day, and full expansion with the foam smell fading takes a few days.
What size is the California King?
It measures 84 inches long by 72 inches wide, which is longer and narrower than a standard King. Check your frame and sheets fit that footprint.
