Our take on the Sweetnight Medium Cooling Gel Memory Foam Mattress in a Box

The Sweetnight Cooling Gel Memory Foam Mattress is a bed-in-a-box that pairs a gel-infused memory foam top with a support core, sold in Twin through California King and in 12 or 14 inch thicknesses. The gel layer is meant to pull heat away and the foam cradles pressure points, so it suits side and back sleepers who want a soft-to-medium feel. It competes with other boxed foam beds on price and convenience rather than on premium materials, and owners rate it well overall while noting it sleeps warm and softens over time. The 14 inch version adds more foam, which most buyers find more supportive than the 12 inch.

Questions and answers

Is the Sweetnight mattress good for side sleepers?
Yes. The soft memory foam top cushions shoulders and hips, which side sleepers tend to like. Stomach sleepers usually want something firmer.
Does the cooling gel keep it from sleeping hot?
It feels cool at first, but many owners still say it sleeps warm. Hot sleepers should weigh that against a latex or hybrid bed.
Should I get the 12 inch or the 14 inch?
The 14 inch adds more foam and feels more supportive, which heavier sleepers tend to prefer. The 12 inch is a lower-profile, softer option.
How long does it take to expand after unboxing?
Most owners say it reaches full shape within 24 to 48 hours. A slight smell may linger for the first few nights.
Does it work on an adjustable base?
Yes. The all-foam build bends on adjustable frames, and it also works on a slatted frame or box spring.
Is it firm enough for couples?
It is soft to medium, so it suits couples who like a hugging feel. Motion transfer is low, but edge support is weak.
