I contemplated this purchase for about six months, but one day two months ago I decided to purchase this mattress in the medium firmness. I based my decision to order this particular mattress on all the positive feedback. I didn't think I could go wrong. Wrong! I've woke up aching every morning since I started sleeping on it, and so has my husband! Don't buy a mattress that you can't lie on and try out in a store, and return if you don't like it. I don't understand how all these people love this mattress!
