Is the Peak 2.0 12 Hybrid good for side sleepers?

It leans firm, so strict side sleepers may find the shoulder and hip pressure too much. Side sleepers who prefer a firmer bed, or who weigh more, tend to do better on it.

The pocketed coil core lets air move through the bed better than a solid foam block. Most hybrid owners report it sleeps cooler than all-foam mattresses, though the foam top layer still holds some heat.

What foundation does it need?

It works on a platform bed, a box spring or an adjustable base. A slatted base should have slats close together, and a sagging or weak frame will shorten the mattress's life.

How does it compare with an all-foam mattress?

It is bouncier, firmer at the edge and breathes better, but it transfers more motion and weighs more. All-foam beds isolate movement better and are easier to move.

Is a 12-inch hybrid thick enough?

Twelve inches is a standard thick profile with room for a coil core plus comfort foam. It fits standard sheets and sits at a typical height on most bed frames.
