Memorial Day may have ended but the best of the sales haven't and I've rounded up three queen mattresses under $300 to prove it. My favorite deal is the Siena Signature Mattress, now $294 in a queen at Siena, a supportive foam mattress with cooling capabilities that exceeded our expectations.The Siena is in our best mattress of 2026 guide as our top cheap pick, but its low price is no reflection of its high-quality build. In fact, many of the budget beds we've tested, from the all-foam Zinus to the hybrid Linenspa mattress below, have outperformed their cheap price tag.The Memorial Day mattress sales are still going for now but based on our previous sales experience they're likely to end soon. Which means this may be your best opportunity to buy the Siena, Zinus Green Tea Memory Foam, and the Linenspa Memory Foam Hybrid mattresses for under $300 in a queen.
