After trying two top online brands (Saatva and Puffy), recommended for side sleepers, and returning them because of shoulder, hip or lower back pain, I was so relieved to find the Helix brand gave me the best sleep. No aches or pains at night or waking up. I even had tried sleeping on a store mattress I bought for my guest room but after an hour it was giving me hip pains. Just when I didn’t think the right mattress for me existed, I sent for the Helix and I’m so glad I didn’t give up.
