I purchased a Tuft & Needle mattress for my guest bedroom. It arrived quickly, the price was great and it is good quality. In fact, it is so comfortable I'm thinking of buying another one for my bedroom.
Have only had the mattress for a couple of weeks but so far we are satisfied.
Would recommend based on ease of ordering, price and return policy. Although I have to tell you I have not found a charity on Long Island that will take mattresses so that might be an issue.
