Great mattress pad
My son and I both have RA, fibro and hEDS, so it's difficult to find a comfortable mattress. I bought one of these a few years ago for myself, and it's still in great condition--hasn't flattened or developed dips like the cheap egg crate mattress pads from big box stores. I just bought one for my son and have gotten rave reviews. If you have trouble sleeping due to chronic pain, this is what you need.
