Is the Tranquillium good for side sleepers?

Yes, the foam contours shoulders and hips. It runs firm at first, so heavier side sleepers may want a softer topper.

The gel-infused foam is designed to pull heat away and owners generally find it cooler than plain memory foam, though it is still an all-foam bed.

How does it compare with a hybrid mattress?

It has no coils, so it is quieter and motion-isolating but less bouncy and with softer edges than a hybrid.

The compressed mattress and a soft knit cover. A foundation or platform bed is needed; it is not adjustable-base compatible in every size.

Most of the expansion happens within a day, with full loft reached over a few days.

It fits one adult sleeper. Couples or anyone who moves a lot at night should look at Full or Queen.
