Someone asked a question recently. She was looking for a firm mattress less than a foot thick. And she wanted it to be all foam, not a hybrid. Most brands sold online that come in firm are 12 inches thick or more. In addition, she’s on a budget so the price needs to be under $300.
So we went looking for a lower profile mattress that fit her request and boy did we them! Note that there are affiliate links in this post which means we may earn a commission when you shop through our links.
Here are some options for her and anyone looking for a good deal on a firm mattress under 12″ thick. Click on the image to go to the mattress.
LUCID 5 Inch Gel Memory Foam Dual-Layered-CertiPUR-US Certified-Firm Feel Mattress, Queen
At the time of writing a queen was a steal at $115!! We prefer Lucid over Linenspa – if this is the price this is the cheapest bed on our list.
Linenspa 5″ Gel Memory Mattress
This is one of the shortest mattresses we have found and it’s cheap too. A queen is under $150.
Signature Design by Ashley – 8 Inch Chime Express Memory Foam Mattress – Firm
This is another low profile mattress and it’s under $150 for a queen.
Synwell Sleep Cool and Firm Gel Infused Ergonomic Memory Foam Mattress, 8 Inch, Queen
Another highly rated mattress, this one is designed to be firm and sleep cooler. The queen size came in at $255.
7 Inches Deep Firm Mattress
This isn’t a brand we’re very familiar with but it’s called Dreamfoam Bedding, which is owned by Brooklyn Bedding (which we’ve heard of). The model is called Doze. It comes in a 7 inch, 9 inch or 11 inch. However, only the 7 inch is firm. The 9 inch is medium and the 11 inch is medium soft. So they get more plush as you add inches to the height of the bed.
You can use these shorter mattresses on bunk beds, trundle beds and more.
Full XL Size Mattress and Frame
Doze comes with a 120 day trial and a 10 year warranty. Best of all you can’t beat the price! And it’s not from China either – it’s made in the USA. It’s not a luxury bed but ideal for kids, RVs, guest rooms and more. A queen 7 inch mattress is just $174! And financing starts at a low $15/month. Amazingly enough shipping is free. This is the first time we’ve seen a full xl. What’s the difference between a full and a full xl? The full xl is an additional 5 inches longer than a regular full! So a full XL is the width of a full and the length of a queen. The dimension are 54″ x 80″.
We found a full XL bed frame in case you’re looking for this unusual size.
