I like that the base is made of springs but it also has memory foam on the top, having the best of both, a bit of firmness and the softness of a pillow. The cover can be removed for perfect washing
My favorite part is that it minimizes movement when my husband is tossing and turning.
I've been sleeping on this mattress for a month now and I absolutely have better nights and less back pain.
Highly recommend Tuft & Needle Mint Hybrid Mattress
