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.
All these beds mix a firm feel with the body-contouring pressure relief of memory foam, supporting the hips and spine to keep back pain at bay. Some of these deals are only sticking around for today's Memorial Day mattress sales, so we reccomend snapping them up while you can.
What is a firm mattress?
A firm mattress is any bed with a harder feel and a high firmness rating (usually 8 or over). While the majority of the best firm mattresses don't go over 8/10, you can get some with a firmness rating of 9 or even 10/10. Most firm mattresses have an innerspring, hybrid, or latex design thanks to the sturdy, supportive materials used, but there are plenty of memory foam beds with a firm feel, too.
