Tuft and Needle offers a firm or firmer mattress. The Mint Mattress supports side and back sleepers, while the Original mattress supports stomach and back sleepers. The Hybrid mattress supports all sleep types.
According to a 2015 review, researchers found that most people reported better sleep quality, comfort, and spinal alignment on a self-inflated, medium-firm mattress. However, the results of several studies are subjective reviews from users, with limited standardization between studies.
Some people may enjoy the firmer feel of the mattresses, while others may find them too firm.
