It may not be an official Memorial Day mattress sale, but Allswell is having a killer sale that you don't usually see outside of major holidays. The sale applies to Allswell mattresses, the company's top-of-the-line mattresses.

For a limited time, Allswell is offering 15% off sitewide with our exclusive "FUTURE15" coupon. After the discount, you can get an Allswell mattress (queen) for $318.75. This is a $56 discount and one of the best mattress deals we have seen. This coupon can also be used on bedding and comforters.

If you haven't heard of Allswell, the Walmart-owned startup offers high-end home goods at affordable prices. For example, while most hybrid mattresses cost over $1,000, the Allswell Luxe is only $548 right now while it is on sale.

The Allswell Luxe hybrid mattress is a fantastic bed-in-a-box mattress made from memory foam and coils. The individually wrapped coils reduce motion transfer, while the layers of memory foam provide cushioning and support; Allswell classifies this mattress as medium firm and offers a 100-night trial and a 10-year warranty.
