About the Gravellaire Sleep Mattress in a Box

The Gravellaire Sleep Mattress in a Box is a 10-inch hybrid queen that pairs gel memory foam with individually wrapped pocket coils and a Eurotop cover. It is sold compressed and rolled, so it expands after unboxing. At $157.99 at Walmart as of November 7, 2026, it sits at the only price recorded since tracking began on November 3, 2026, so there is no lower recent price to wait for. That is very cheap for a hybrid queen, and the spec sheet lists a sofa bed specialty style, which is worth confirming before you buy.

Questions and answers

Is $157.99 a good price for this mattress?
It is the only price recorded since November 3, 2026, and it is low for a hybrid queen. There is no cheaper recent price to wait for.
How firm is it?
Buyers describe it as medium-firm, with firm support under soft cushioning. Back sleepers report good support.
Does it work on an adjustable base or sofa bed frame?
The listing tags it as a sofa bed specialty style, so check the frame's size and weight limits before using it that way. A compressed hybrid usually needs a flat, supportive base.
How long does it take to expand?
Buyers say it expands quickly after unboxing and holds its shape. Give it up to a day to reach full height before judging the feel.
What is in the box?
One queen mattress, compressed and rolled in a box. A frame and foundation are not included.
Is it good for couples?
Pocket coils reduce motion transfer, which helps if one sleeper moves at night. The soft edges are the main trade-off.
