Firm mattresses sometimes get a bad rap for being perceived as uncomfortable and too stiff, but if you find the right one, it can give you the best support and comfort. In the event that your bed is too firm, mattress toppers are a great solution to add a bit of cushion.

If you prefer feeling like you’re sleeping “on” your bed rather than “in” it, or if your mattress has you waking up sore, then a firm mattress might be exactly what you need. The testing gurus at Mattress Advisor poured hours of research and data from their testing lab to find the best of the best firm mattresses.

Who Should Sleep on a Firm Mattress?

Back and Stomach Sleepers

Extra firmness promotes spine alignment and provides pressure relief for back and stomach sleepers, which helps prevent morning stiffness and back pain.

Firm Mattress Lovers

Firm mattresses are also a great fit for people who enjoy extra support and feeling elevated, or like the feeling of sleeping “on top” of the bed rather than sinking into it.

Couples

Firm mattresses tend to isolate motion well, meaning if one partner tosses and turns, the movement won’t spread across the mattress. Firm mattresses also offer strong edge support, which allows two people to utilize the full area of the bed without feeling like they’re going to fall off the side.

Firmness Levels of Different Mattress Types

Firmness is measured with a 10-point scale, with one being the softest and 10 being the firmest. Measuring firmness is subjective, however, and the materials of the mattress can make a big difference. Mattresses come in four basic types: memory foam, innerspring, latex, and hybrid. Memory foam mattresses have a contouring effect that may make a firm mattress feel a little less stiff. Innerspring mattresses are made with a system of interconnected coils. Latex mattresses are made from natural or synthetic latex, and a firm latex mattress typically falls somewhere in between the memory foam and innerspring options. Hybrids can combine some or all of these materials to create one unique, firm bed.
