Is the GREOO 12" mattress good for side sleepers?

It is built for all sleep styles with body-mapping foam over pocket springs. Some lighter side sleepers find it firmer than expected, so pair it with a soft topper if you need more cushioning.

The gel-infused foam and spring core are designed to move heat and air better than all-foam beds. Most owners report it sleeps at a normal temperature.

How does it compare with all-foam mattresses?

The spring core adds bounce, edge support and motion isolation that all-foam beds often lack. It is also thicker and heavier than most foam-in-a-box models.

What is included with the mattress?

It ships compressed and rolled in a box as the mattress only. A foundation or frame is sold separately.

How long does it take to expand?

It typically takes a day or two to reach full height after unboxing. Some odor may linger during that time.

Does it work on an adjustable base?

A hybrid with pocket springs can flex on an adjustable base, but check the base's weight limits. The mattress is rated for up to 1,000 lbs.

Our take on the GREOO Queen Size Mattress in a Box 12"

The GREOO 12" is a hybrid queen mattress in a box that pairs gel-infused foam with a pocket-spring core, sold as an eight-layer build aimed at all sleep positions. It claims more coils than typical hybrids for motion isolation, reinforced edges for a full usable surface, and a 1,000 lb weight rating. Against rivals like Casper, Nectar and DreamCloud, it leans on a thicker profile and a long 365-night trial with a 10-year warranty. Owners rate it 4.3 out of 5 across 1,710 ratings, with most praise for comfort and value and some complaints about firmness and off-gassing.

About the GREOO Queen Size Mattress in a Box 12"

The GREOO 12" Queen Mattress is an 8-layer hybrid mattress that ships in a box. It combines CertiPUR-US certified foam with pocket springs.

A cooling gel foam layer dissipates heat faster than standard foam. The pocket springs isolate motion, and the layers are designed to relieve pressure at the hips and shoulders while supporting spinal alignment for back, side and stomach sleepers.
