Layla Sleep - Memory Foam Mattress

One mattress, two firmness levels: flip it from the soft side to the firm side instead of guessing right the first time.

The Layla Memory Foam Mattress is a 10 inch all-foam bed built around a design most brands do not attempt: it is flippable, with a soft feel on one side and a firm feel on the other. Both sleeping surfaces carry a layer of copper-infused memory foam, so flipping changes the firmness without changing the material you sleep on. Six sizes run from Twin at $649 to King and Cal King at $1,149, with the Queen at $999 at the time of this review.

The flip is the practical hook. Firmness is the hardest thing to judge when buying a mattress online, and here a wrong guess costs you thirty seconds of effort instead of a return shipment. Layla backs the choice with a 120 night trial, free shipping and returns, and a lifetime warranty that covers sagging beyond 1 inch, loss of shape, and loss of mattress height.

The trade-offs are the ones inherent to all-foam construction. You get the slow, contouring response of memory foam rather than the springy pushback of coils, and the 10 inch profile is slimmer than many current beds, which larger sleepers should factor in. Using the second firmness also means physically flipping the mattress, so plan on a second set of hands for the bigger sizes. If you want coil response with the same flip concept, Layla's own Hybrid covers that at a higher price.

On the product page the mattress shows a 4.6 average across 8,648 reviews. At $649 to $1,149 across sizes it sits at the accessible end of the category while offering a feature, two firmness options in one bed, that usually requires buying twice.
