The memory foam is wonderfully soft and cozy, while the individual springs provide excellent support without that overly bouncy feel. The motion isolation is impressive, so you won’t be disturbed if someone moves beside you. It strikes a great balance between comfort and firmness, making it ideal for deep, restful sleep. The quality feels premium, yet the price is very reasonable, which makes it a fantastic value. Setup was simple, and the mattress quickly expanded to its full shape. I’ve been waking up feeling refreshed and pain-free, and I’d highly recommend it to anyone looking for both comfort and durability at a fair price!

This mattress was the best gift I could have given! My mom has had a ratty old mattress for as long as I could remember and I wanted to get her something new without spending too much money (in case it wasn't the right fit for her). It was super easy for me to lift with another person - not too heavy to carry upstairs. Additionally, it was really easy to set up - just cut the plastic with the included tool and it unrolls on its own. It took about 24 hours fully inflate and settle before laying on it and it was amazing. Super comfortable and noticeably firm without feeling like concrete. The mattress was a great purchase for the price and my mom said that it was the best sleep she has gotten in ages. It ended up being about 12 inches tall and fit a deep-pocket mattress really well. I would 100% order again.

Very easy to put together and light weight. Thankfully that my storage bins fit underneath the bed. Very soft.

I bought this mattress intending to send it overseas, but when shipping fell through, I decided to keep it — and it has completely transformed my nights. From the very first sleep, I could feel the difference: the memory foam gently cradles every curve, while the independent springs provide firm, perfect support. Motion isolation is flawless — even if someone moves on the other side, I stay in deep, uninterrupted sleep. Every morning I wake up feeling fully recharged, refreshed, and pain-free, like I’ve been treated to a luxury hotel experience in my own bedroom. What started as a shipping mishap turned into the best gift I’ve given myself, and I can honestly say this mattress has changed the way I rest, recover, and live.

The mattress is comfortable and supportive. It has enough softness on top without sinking in too much, and the springs give it a solid base. I was able to set it up quickly after unboxing, and it expanded to full size within a few hours. Sleeping on it has been easy, and I’ve noticed less tossing around at night. For a queen size, it feels roomy and works well.
