Our take on the Sleep Medium Memory Foam Mattress

This is a medium-firm memory foam mattress sold in six sizes and five thicknesses from 6 to 14 inches. The 8-inch version is the most common pick and the one Wayfair lists as its verified model. At $145.99 for the 8-inch queen at Wayfair as of November 4, 2026, it sits at the low end of what this line has sold for, so the current price is a good one for a basic foam bed.

Questions and answers

Is the 8-inch or 10-inch version better?
The 8-inch is the cheapest and fine for kids, guest rooms and lighter adults. Go to 10 or 12 inches if you weigh more or want more cushioning between you and the base.
Does it work on an adjustable bed?
Yes. It is all memory foam with no coils, so it bends with an adjustable base. Use a solid or slatted foundation rather than a box spring.
How long does it take to expand?
It ships rolled and compressed. Give it 24 to 72 hours to reach full thickness, and expect a mild foam smell that fades in a few days.
Is $145.99 a good price?
Yes. That is the best new price across stores as of November 4, 2026, and it is at the low end of this mattress's recent range. Only one store currently lists it new, so compare sizes before buying.
What sizes and thicknesses are available?
Twin, Twin XL, Full, Queen, King and California King, in 6, 8, 10, 12 and 14 inches. Not every size and thickness combination is stocked at every store.
