Yawnder mattress reviews · Updated October 2026
The Brentwood Home Crystal Cove offers two distinct sleeping surfaces: a softer memory-foam side and a firmer latex side, both supported by pocketed coils. That makes it appealing if you want a real choice of feel in one mattress, though flipping a heavy hybrid takes some effort.

Our hands-on experience
When we originally unboxed the Crystal Cove, the mattress was unusually heavy and tightly compressed. Once the packaging was opened, it regained its shape quickly. We found the two sides offered meaningfully different feels: the charcoal-infused foam side was plusher, while the natural-latex side felt firmer and more buoyant. These observations describe the sample we reviewed, not a new test of every current production version.

Construction and materials
Brentwood Home currently describes a dual-sided hybrid with an organic latex layer on one side and charcoal-infused memory foam plus Flow Foam on the other. An eight-inch zoned pocket-coil unit sits between the comfort surfaces; the brand also describes a reinforced perimeter. Its current listing identifies the mattress as vegan and GREENGUARD Gold certified. Check the manufacturer’s current specifications for the precise version and certifications.
Flipping changes which comfort layer faces you; it does not turn one mattress into two independently adjustable halves. If partners prefer different surfaces, both will have to agree on the side in use.
Firmness and sleeping positions
Side sleepers: The softer foam side is the logical starting point if your shoulder or hip needs more cushioning. People who prefer a firmer surface may find the latex side comfortable, but pressure relief depends on body weight and preference.
Back and stomach sleepers: Try the latex side first if you prefer less sink. Check whether your hips feel supported without creating pressure at the lower back; neither side can guarantee a particular alignment for everyone.
Combination sleepers: Latex has a springier, more responsive feel than memory foam and may make changing positions easier. The foam side offers more of a contouring sensation.

Motion, edge support and temperature
In our original review, the coil system provided edge stability and responsiveness. The foam side may absorb movement differently from the latex side, so couples should test both. Pocketed coils allow more airflow through the core than a solid foam base, but bedding, room temperature and the sleeper all affect heat; no material guarantees a cool night.
Price, shipping and trial
Prices, sizes and availability change. Brentwood Home currently lists a one-year mattress trial with a 30-day adjustment period and a 25-year limited warranty; confirm eligibility and the latest terms before ordering. Because the mattress is heavy, plan for a second person when moving or flipping it.
