Our take on the Gravellaire 12" Queen Mattress in a Box, Gel Memory Foam and Pocket Spring Hybrid Mattress, Medium Comfort, Pressure Relief, Adult

The Gravellaire is a 12-inch queen hybrid that pairs gel memory foam with individually wrapped pocket coils for a medium feel. The foam is CertiPUR-US and OEKO-TEX Standard 100 certified, and the knit cover and breathable layers are built for airflow. Reinforced edges and a non-slip base round it out. It suits side and back sleepers and couples who want motion isolation without a full-foam feel. Against all-foam rivals it adds coil bounce and edge support; against premium hybrids it is a simpler build with fewer comfort layers.

About the Gravellaire 12" Queen Mattress in a Box, Gel Memory Foam and Pocket Spring Hybrid Mattress, Medium Comfort, Pressure Relief, Adult

This is a 12-inch queen hybrid mattress that combines gel memory foam with individually wrapped pocket springs. It has a medium comfort feel and is built to relieve pressure on the shoulders, back and hips while supporting the spine.

The high-density gel memory foam contours to the body and resists sagging. The pocket coils give targeted support and reduce motion transfer. Breathable comfort layers and a knit cover improve airflow and help dissipate heat.

Reinforced edges add stability and usable sleep space, and a non-slip base helps keep the mattress in place. The foam components are certified by OEKO-TEX STANDARD 100 and CertiPUR-US and tested against over 1,000 harmful substances.

Questions and answers

Is this mattress good for side sleepers?
Yes. The gel memory foam contours to shoulders and hips, which is where side sleepers need pressure relief. The medium feel and coil support suit most side and back sleepers.
Does it sleep hot?
The breathable knit cover and airflow layers are designed to dissipate heat, and gel foam helps. Most owners report it sleeps reasonably cool for a hybrid.
How does it compare with an all-foam mattress?
It adds pocket-coil bounce and reinforced edges over an all-foam build, with less sink-in. Motion isolation is good but not as complete as a dense all-foam bed.
What is the firmness?
It is a medium feel. Stomach sleepers and those who want a firm bed may find it too soft.
What certifications does it carry?
The foams are CertiPUR-US certified and the mattress is OEKO-TEX Standard 100 certified, meaning the foam is tested against harmful substances.
Does it need a box spring?
It works on a platform bed, slatted frame or adjustable base. A solid or slatted foundation is enough; a box spring is not required.
