Our take on the NightyNight 12" Twin Size Firm Mattress

The NightyNight 12-inch Twin is a medium-firm foam mattress with a breathable knit cover, green tea infusion and CertiPUR-US and OEKO-TEX certifications. At 12 inches it is thicker than most twin foam beds, which suits adults and guest rooms better than thin starter mattresses. The medium-firm feel targets back, side and stomach sleepers, though hot sleepers should note that foam still traps some heat despite the airflow cover. Reviewers rate it 4.4 out of 5 across 28 ratings.

Questions and answers

Is this mattress good for side sleepers?
It is medium-firm, which supports side sleepers but may feel hard to lighter side sleepers. Heavier side sleepers usually get enough give.
Does the 12-inch thickness matter?
Yes. A 12-inch foam mattress has more support layers than thin 6- to 8-inch twins, so it feels more like a regular bed and suits adults and guests.
Will it sleep hot?
The knit cover and airflow layer help, but it is still foam. Very hot sleepers may prefer a hybrid or latex mattress.
What certifications does it carry?
The foam is CertiPUR-US certified and the fabric is OEKO-TEX certified, meaning low emissions and no harmful chemicals.
Is a twin the right size?
A twin fits one adult or a child and works for guest rooms, dorms and bunk beds. Couples need a full, queen or king.
