I have low back pain and I’ve tried a number of mattresses Including Leesa and Loom and Leaf. This is by far the best mattress I’ve ever slept on. It’s exactly the right blend of fitness and give. I’m a back sleeper and I wake up without back pain. It’s gotten to the point where my husband and I are loathe to go out of town because other mattresses just don’t compare. Highly recommend.
