While memory foam beds are known for their sink-in softness and comfort, I've found there are plenty of firm memory foam mattresses to buy in the Memorial Day sales. The best firm mattress deal is by Brooklyn Bedding, where you can save 30% on the Plank Firm at Plank Mattress and get a queen size for $932.40 (saving you $399).
The Plank Mattress is one of this year's best mattresses for those looking for a hard bed that supports the spine and alleviates back pain. However, there are plenty more firm all-foam beds on the market, including budget beds from Lucid and Siena.
