Soft vs. Firm: What Matters?
A mattress that is too soft can let your hips sink, while one that is too firm can feel hard on the shoulders. In a study of people with chronic low back pain, a medium-firm mattress did better than a firm one.[1] So extra firm isn’t automatically better for back pain. Stomach sleepers, back sleepers and heavier people are the ones most likely to enjoy an extra-firm feel. If you have back or neck pain that doesn’t go away, see a doctor.[2]Who Likes an Extra Firm Mattress?
Extra-firm mattresses sink less under your weight, so you sleep more on top of the bed. Many people who sleep on their stomach or back like this feel, as do heavier sleepers who find softer beds sag. Side sleepers often find extra firm too hard on the shoulders and hips. If you’re unsure, look for a long sleep trial so you can try the feel at home.Features of a High-Quality Extra Firm Mattress
Good extra-firm mattresses usually have one or more of the following features:- Orthotic Design – some extra firm mattresses have notches, grooves, or ridges in odd places. Makers zone the support so the hips and shoulders get different firmness. Make sure you are the right size if a mattress has a built-in body-contour design.
- Memory Foam – a thin memory foam top layer adds some contouring to a firm mattress.
- Multi-Layered – foam technology hasn’t stopped at memory foam, though. Some mattresses have multiple foam layers, each with a different job, such as comfort or support.
