Comfortable but corners haven’t decompressed like the rest of the mattress so it dips.. Allen. Washington, Dc. Tue Sep 21 2021

The bed that started it all, the Purple Mattress features two inches of breathable GelFlex Grid to cradle pressure points like hips and shoulders while keeping the rest of your body fully aligned. When paired with a dual-layer comfort foam base, the result is a perfectly supported sleep.

The mattress expanded properly. I have never ordered/bought my own mattress just for myself, so in all honesty, I had no idea what I was doing. It fits my daybed perfectly, and is very firm. I ended up getting a mattress topper, but if you're looking for firm, it's a great purchase.. Anonymous. Tue Dec 30 2025

Experience the perfect balance of comfort and support with this medium foam mattress. Crafted with memory foam, it contours to your body, relieving pressure points for a restful night's sleep. With low motion transfer and a breathable design, it's ideal for both residential and non-residential use. Sleep like an adult.

The mattress is beyond comfortable and fit perfectly in the new bed frame. I’m a stomach sleeper and this mattress is the best I’ve ever used. Highly recommended!. Maria. Salem, MA. Tue Apr 15 2025

The powers of springs and foam combined — for an update on our classic. We designed our own proprietary foam for our “just right” feel, and are now integrating those layers with resilient-yet-gentle springs. Responsive springs provide active support while Zoned Support foams treat your shoulders and hips differently for better spine alignment. Stay cool and asleep throughout the night thanks to airflow-friendly coils and breathable open-cell foams.

Just what I needed and very comfortable. Michael. Little Rock, AR. Thu Oct 05 2023
