Alwyn Home 12" Medium Memory Foam Mattress

About This Product

This 12-inch mattress pairs gel-infused, egg-crate memory foam with a breathable knit cover to keep you cool all night, while layered comfort and high-density base foams cradle pressure points and align the spine. Motion-absorbing foam stops partner disturbance, CertiPUR-US-certified materials keep chemicals and allergens out, and a removable, machine-washable rayon cover stays fresh. Arrives compressed, expands in minutes, and fits any full frame—platform, slats, adjustable, box spring, or floor—for effortless setup and cleaner, deeper, uninterrupted sleep.

Features

Sleep cool until sunrise thanks to a gel-swirled memory-foam top that breathes. An open-cell, egg-crate core channels air while the moisture-wicking knit cover flushes heat away, so you never wake up sweaty.
Below that, a 12-inch stack of responsive comfort foam and body-hugging memory foam spreads weight evenly, lifting pressure off shoulders, hips and back. A dense base layer locks your spine in neutral, cutting morning aches.
The foam core swallows motion—roll, kick or climb out; your partner feels nothing and you keep dreaming.
Every layer is CertiPUR-US-clean: no harsh chemicals, no fiberglass, no formaldehyde. The hypoallergenic rayon-blend cover is gentle enough for kids and sensitive skin.
Shipped shrink-wrapped and boxed, it unfurls in minutes onto any full frame—platform, slats, adjustable base, box spring or the bare floor. Need a refresh? Zip off the cover and toss it in the wash.
