Is this mattress good for side sleepers?

Mostly no. A firm memory foam surface can press on shoulders and hips for side sleepers. It suits back and stomach sleepers better.

Does it need a box spring?

No foundation is included, and it does not require a box spring. A platform base, slatted frame or box spring all work.

How firm is it really?

It is a firm mattress. The memory foam softens the top slightly, but the core stays stiff, so expect little sink.

Memory foam tends to trap heat, and this model has no cooling gel or breathable cover. Hot sleepers may notice warmth.

It measures about 79.5 inches wide by 76 inches long, which is wider and shorter than a standard king.

Does it work on an adjustable base?

An all-foam mattress generally bends on an adjustable base. Check the base's weight limits and warranty terms first.

Our take on the Jeny Firm Memory Foam Mattress

The Jeny Firm Memory Foam Mattress is an all-foam bed with a firm feel, sized at roughly 79.5 by 76 inches, so it is wider than a standard king and closer to a true square. The memory foam layer cushions pressure points while the firm core keeps the surface from sinking too far, which suits back and stomach sleepers and heavier adults. It is a plain, no-frills design: no cooling gel, no zoned support, no handles, and no foundation included. Rivals in this class usually add cooling covers or edge support, so the Jeny leans on a simple firm feel rather than extras.
