This Amazon deal is no longer available, but you can now buy an EGOHOME Plush Mattress for under $300 in a queen at Amazon.

I've tested plenty of luxury mattresses but it's actually a budget-friendly bed that I think suits my sleep style the best — and it's even cheaper ahead of the 4th of July mattress sales. The EGOHOME Black 12" Memory Foam Mattress, now just $299.99 for a king at Amazon, is ideal for those anyone who wants a cheap mattress that provides more excellent support.

We rate memory foam mattresses among the best mattresses we've tested. Always under $400 for a queen, the EGOHOME Black 12" Mattress is one of those memory foam beds that prove this mattress type has stepped up its game. It supported me in all sleep positions, and I could even sleep right up to the edges without feeling as if I was going to roll out of bed.

This Amazon deal offers outstanding value for money not only because it's offers you the chance to buy a king mattress for under $300, but because the same size and model at EGOHOME's official website is $499.99. Here's why I think this $200 discount is the best 4th of July mattress deal so far, plus what I loved about reviewing the EGOHOME Black 12" Memory Foam Mattress.

Support for all sleepers at a budget price

I slept on the EGOHOME Black 12" Mattress from May 2025 to April 2026, and I was impressed by how comfortable and supported it kept me through the year. Its testing followed my Leesa Legend mattress review, and I must say that I much preferred the EGOHOME over the luxury Leesa.

What I like about the EGOHOME is that it provided a slight hug when side sleeping but it firmly supported me when back and stomach sleeping. In fact, I named it one of the best cheap mattresses on the market.

It also has sturdy sides for sleeping, sitting, and getting in and out of bed. Motion isolation scored well, too, so I can recommend the bed to couples as well. However, just keep in mind that, despite the copper gel infusion, the temperature regulation isn't the best, and the bed can get a little stuffy. For a more breathable feel, check out our EGOHOME Black 12" Hybrid Mattress review.
