Our take on the NightyNight 6" Twin Size Firm Memory Foam Mattress, Cooling & Green Tea Refreshing Design, Washable Cover, No-Slip Base

The NightyNight is a 6-inch twin memory foam mattress with a medium-firm feel, a breathable knit cover and a green tea infusion in the foam. The low profile suits bunk beds, trundles, guest rooms and kids' rooms where a thicker mattress would sit too high. It is CertiPUR-US certified foam with OEKO-TEX certified fabric, which is more third-party certification than most budget memory foam twins list. Reviewers rate it 4.3 out of 5 across 24 ratings, and the common complaints are about firmness and edge support rather than durability.

Questions and answers

Is a 6-inch mattress thick enough for an adult?
It works for lighter adults and back or stomach sleepers. Heavier adults and side sleepers usually want 8 inches or more for cushioning.
Does it work on a bunk bed?
Yes. The 6-inch profile keeps the top rail usable on most bunk beds and trundles, where a standard 10-inch mattress sits too high.
Is the cover removable and washable?
Yes, the knit cover is washable. The foam core itself should not be washed.
Does the green tea infusion make a difference?
It is meant to keep the foam fresher. It does not change the firmness or add meaningful cooling on its own.
What certifications does it carry?
The foam is CertiPUR-US certified and the fabric is OEKO-TEX certified, so both are screened for harmful substances.
How firm is it?
It is medium-firm. Most back and stomach sleepers find it supportive, but side sleepers often want something softer.
