I know from two years of tracking major mattress sales that big deals remain live after the federal holiday ends... but not for long. Final-call sales, such as an amazing deal where you can buy a queen Memory Foam Mattress for just $262.49 at Lucid, can disappear at any moment — so you'll need to act fast.

In fact, I've seen plenty of queen-size mattresses under $400 thanks to the extended Labor Day mattress sales, but they show no indication of when exactly they'll end. That means Amazon may pull the plug on a discount that gets you over 10% off a queen Zinus Green Tea Memory Foam Mattress, our favorite budget choice in our 2025 best mattress guide.

We're still tracking the newest last-chance-saloon deals in our Labor Day mattress sales live hub, but I've saved you the trouble of hunting for queens under $400 with this quick round-up...

2. EGOHOME Black 12" Memory Foam Mattress: queen was $699 now $314.50 with code LABORDAY15 at EGOHOME
I tested the memory foam version of EGOHOME'S bestseller for the EGOHOME Black 12" Memory Foam Mattress review, and I was immediately impressed with how high quality and supportive the cheap mattress was (and still is, I'm currently still sleeping on it). A queen now has an extra 15% off with code LABORDAY15 (automatically added to cart) so you'll find it for $314.50 instead of $369.99. Extras include free shipping, a 100-night sleep trial and a 10-year warranty.

3. Linenspa 10" Memory Foam Hybrid Mattress: queen was $299 now $254.99 with TAKE15 code at Linenspa
The best hybrid mattresses are supportive, comfortable, but also outside a lot of budgets. However, the Linenspa Memory Foam Hybrid is an affordable 10" hybrid mattress that's only $254.99 for a queen with code TAKE15. We tested the 8" version for the Linenspa Memory Foam Hybrid Mattress review, so this 10" model is bound to pack more of a comfortable and supportive punch. There's no trial, but you do get 30-day returns, free shipping, and a 10-year warranty.

4. Lucid 10" Memory Foam Mattress: queen was $349.99 now $262.49 at Lucid
Lucid has always been a budget-friendly brand on our radar due to their popular selection of mattresses and bed toppers. Thanks to a 25% off sale, its best-selling memory foam mattress is now $262.49, and you'll get a 100-night sleep trial, free shipping and a 10-year warranty. It's available in three firmness levels, but the queen is fast-selling so only available in Firm (designed for stomach sleepers) or Plush (designed for side sleepers).
