Features
- Luxurious Comfort for Sleep: The Onlylucky 12 inch full mattress is constructed with innovative materials, featuring three layers of functional foam and individually pocketed coils system. The synergistic combination of gel memory foam and pressure relief foam effectively distributes body pressure while conforming to body contours, seamlessly adapting to diverse sleepers. As you sink deeper into the twin size mattress, the high density foam dynamically increases its support density, delivering an exclusive comfort experience.
- Advanced Cooling Technology: The Onlylucky full size memory foam mattress is made with finely woven, breathable fabric that allows air to flow freely, effectively dissipating steam and sweat from the surface to keep your body comfortable and dry all night long. Additionally, the increased foam content with egg-crate foam structure significantly improves internal airflow, preventing heat accumulation and ensuring you stay cool throughout the night.
- 7 Zoned Ergonomic Design: Crafted with ergonomic precision, our OnlyLucky full bed mattress features 7 distinct sleep zones that intuitively cradle your body's natural contours. This intelligent design distributes weight with perfect equilibrium, melting away pressure points while gently aligning your spine into its optimal position. Sleep that feels effortlessly supportive, leaving you waking refreshed, free from aches, and truly recharged.
- Zero Motion Transfer & Undisturbed Sleep: The Onlylucky mattress full size integrates an advanced pocketed coil system with hundreds of individually wrapped springs to prevent tangling. This design achieves zero motion transfer, ensuring undisturbed sleep whether sleeping alone or with a partner. The reinforced edge support maintains stability even when you sit or sleep near the edge, so you dont have to worry about rolling off.
- Enhanced Comfort and Safety: Onlylucky full size mattress is crafted with skin-friendly and fiberglass-free materials. All memory foam is CertiPUR-US certified, ensuring a healthy, luxurious sleep space. Enjoy a 365-night trial to test its balanced blend of support and cushioning, with no odor.

The media could not be loaded. I needed a new mattress and saw the reviews that this one stated that it was firm. I need it a firm bed and this did not disappoint exclamation first of all I am glad that I added the hallway service. My old mattress was removed and the new one was unwrapped and placed in my bedroom. They were able to place it exactly where it needed to go. Even though it came in a box it was quite heavy. It expanded immediately but by the third day it was extra full. I have had no back pains and have slept through the night since day one. This is a great purchase and it was reasonably priced. The mattress had no type of smell and it is very comfortable even though it is firm. I was unsure if it would expand to the full length but it has to wear my sheets don't even fit. I am very satisfied with this purchase

If you are a memory foam die hard, this mattress is not for you. I have been sleeping on memory foam since 2006 and this does not feel like a memory foam. I can hear the springs every time o move in bed. I don't feel them, but I do hear them. My first night on the bed, after only letting it cure for around 6 hours, it was extremely bouncy. After 24hrs, it is barely bouncy. A week later, it still has a minimal bounce, it is quite firm. I am missing the memory foam feel too much, so I am sending this back.
