I am so happy with this mattress! The 14-inch height makes it feel very luxurious, and the combination of memory foam and pocket springs gives the perfect balance between comfort and support. It’s medium firm, exactly as described, and provides excellent pressure relief—I wake up without any back or shoulder pain. The motion isolation is impressive too—no more getting disturbed when my partner moves at night. It arrived well-packaged in a box, was easy to set up, and expanded quickly with no strong odor. The quality feels way above its price, and it looks sleek in my bedroom. Overall, I highly recommend this mattress to anyone looking for a comfortable, supportive, and affordable upgrade. Worth every penny!

This mattress is soooooo comfortable!! Once it was opened and unrolled it expanded quickly! It takes 24-72 hours to expand to its full size but you CAN sleep on it immediately; it doesn’t hurt anything and it’s extremely comfortable! Mine isn’t completely expanded yet. This will be my 3rd night and it’s nice and firm but not too much. Makes ZERO noise if you move around in your sleep. Movement doesn’t disturb anything that may be in your bed with you. (Pillow, pet, significant other). Definitely recommend and I absolutely love the quality and comfort of this mattress! Definitely recommend!!

Wonderful value. Extremely comfortable and enough support with the perfect amount of cushion for my arthritic joints. More like a soft meduim rather than meduim firm. So grateful for a good night sleep.

Overall, this is a good mattress very comfortable and easy to set up. I ordered the queen size 12-inch version, which was advertised as medium firm, but I’d say it’s definitely on the softer side. It’s more like a soft-to-medium feel rather than true medium firm. That said, it still provides decent support and I've been sleeping well on it. Just be aware that if you're specifically looking for something with a firmer feel, this might not be the one. It’s not a dealbreaker for me, but I do think the firmness level should be described more accurately in the listing. Good quality for the price, and it expanded fully within 24 hours. Just wish the firmness matched the description a little better.

I bought this for a guest room and was hoping for just good enough. It far surpassed my expectations so far. It is very comfortable and just as sturdy as my much more expensive one in my room. Upon opening, it expanded almost completely right away and had absolutely no funky smell.

Super fast delivery, height was accurate, easy setup, and super comfy! Softer than I’ve was expecting but that was fine! Expanded within a couple hours - didn’t find the 24hr suggested period necessary.

😊Been wanting an extra firm mattress and this mattress met my expectations. The bedframe doesn't squeak and it's very sturdy. Very easy to assemble. However I wish it was a bit higher than 11 inches. Overall I'm satisfied😍
