Our take on the NightyNight 8" Twin Size Firm Mattress, Cooling Gel Memory Foam Mattress in a Box, Removable, Washable Cover & Non-Slip Bottom

The NightyNight is an 8-inch twin memory foam mattress sold compressed in a box, with a cooling gel and green tea infused foam core and a removable, washable knit cover. It targets side, back and stomach sleepers who want a medium-firm feel without spending much. Against thicker 10- to 12-inch foam mattresses it offers less cushioning and a shorter expected lifespan, and its cooling claims are modest for a foam bed. Owners rate it well overall, with comfort and easy setup standing out and durability over years the main doubt.

Questions and answers

Is this mattress good for side sleepers?
It is medium-firm, which suits many back and stomach sleepers. Side sleepers with broad shoulders or hips may want a softer or thicker mattress for pressure relief.
Does the cooling gel really keep you cool?
The gel infusion and breathable knit cover help airflow, but foam still traps some heat. Hot sleepers should expect modest relief, not the cooling of a spring or hybrid bed.
How long does it take to expand after unboxing?
Memory foam in a box typically reaches most of its shape within a few hours and full height within 24 to 48 hours. Sleeping on it the first night is fine.
Can I wash the cover?
Yes. The knit cover is removable and washable, and the non-slip bottom keeps it in place on the base.
Does it work on a platform bed or the floor?
It works on a platform bed, slatted frame or the floor. A solid, flat base gives the best support for an 8-inch foam mattress.
Is it safe for children?
The foam is CertiPUR-US certified and the fabric OEKO-TEX certified, both meaning low emissions and no harmful chemicals. Let it air out fully after unboxing.
