Is a 6-inch mattress thick enough for an adult?

It works for light adults and occasional use, but most adults sleeping nightly want 8 inches or more. At 6 inches, heavier sleepers are more likely to feel the firm base through the foam.

Does the gel foam actually sleep cool?

Gel infusion helps compared with plain memory foam, but an all-foam 6-inch mattress still traps some heat. A breathable protector and a cool room do more for temperature than the gel alone.

How long until it fully expands?

The mattress is compressed and rolled in the box and expands to full shape within 72 hours. It is usable sooner, but give it the full three days before judging firmness.

Can I wash the cover?

Yes. The knit cover is removable and washable, and it has a non-slip bottom to keep it in place on the mattress.

What sizes and firmness does it come in?

This listing is the Twin, 6-inch gel memory foam version. Firmness is on the firmer side because of the high-density base foam.

Is it safe for a kid's room?

The foam is CertiPUR-US certified and fiberglass-free, and the cover fabric is OEKO-TEX certified. That makes it a reasonable pick for a child's or guest bed.

The mattress arrives compressed and rolled in a single box. Unpack it, let it expand, and it fits standard bed frames.

About the Dealnight Memory Foam Mattress

The Dealnight is a 6-inch gel memory foam mattress in Twin size, sold compressed and rolled in a box. It pairs a cooling gel-infused foam top with a high-density base foam and a removable, washable knit cover. The foam is CertiPUR-US certified and fiberglass-free, and the cover fabric is OEKO-TEX certified. At 6 inches it is a low-profile mattress, so it suits bunk beds, trundles, sofa beds and guest setups more than a primary adult bed.
