Our take on the Dealnight Memory Foam Mattress

The Dealnight is a 6-inch gel memory foam mattress in Twin size, sold as a low-cost option for sofa beds, guest rooms and kids' rooms. The gel infusion is meant to pull heat away from the foam, which matters more on a thin 6-inch slab than on a thick one. At $88.99 at Walmart as of November 4, 2026, it is the only new price listed, so there is no recent range to compare it against.

Pros
  • Low price for a Twin memory foam mattress
  • Gel-infused foam aims to sleep cooler than plain foam
  • 6-inch profile fits sofa beds and low frames
  • Twin size suits bunk beds and small rooms
  • Memory foam cushions pressure points
Cons
  • 6 inches is thin, so support is limited for heavier adults
  • Gel foam still sleeps warmer than spring or hybrid mattresses
  • Only one store prices it new, so there is little price competition
  • No listed firmness choice or trial period
  • Thin foam tends to soften sooner than thicker mattresses

Questions and answers

Is the Dealnight mattress worth it?
At $88.99 at Walmart as of November 4, 2026, it is a reasonable buy for a sofa bed, guest room or kid's room. For nightly use by an adult, a thicker mattress gives better support.
Is a 6-inch mattress thick enough?
Six inches of foam is on the thin side. It works for children, lighter adults and occasional sleeping, but heavier sleepers will feel the base underneath.
Does the gel foam sleep cool?
Gel infusion helps compared with plain memory foam, but a 6-inch foam mattress still traps more heat than a hybrid or innerspring. A breathable protector helps.
Will it fit a sofa bed?
It is a Twin, so check your sofa bed's mattress dimensions before ordering. Twin is 38 by 75 inches, and a 6-inch thickness fits most convertible frames.
What comes in the box?
It ships compressed and rolled. Let it expand for up to 24 to 48 hours before sleeping on it, and expect a mild foam smell that fades.
When is it cheapest?
Walmart is the only store listing it new at $88.99 as of November 4, 2026. Watch for mattress sales around holidays and back-to-school season.
Where is the Dealnight Memory Foam Mattress cheapest?
At Walmart, for $88.99, as of our latest check.
