With the sleek looks and precision manufacturing of its namesake, the Reve Emerald mattress truly is a gem. A product of innovations in the field, this hybrid mattress brings comfort and luxury to the bedroom without emptying the wallet. Expensive mattresses often have up to 3000 springs. Utilizing reflex foam instead of steel, this mattress has millions of "springs". The high-density reflex foam base is an astonishingly comfortable and orthopedic sleeping surface. Composed of polymers calibrated to perfectly mold to your body's pressure points without yielding where you need the most support, Reflex Foam assures you'll wake up from a fantastic night's sleep to a fantastic day. The reflex core of this mattress is topped with 4G Revo visco-elastic memory foam. Using the heat of your own body to shape itself, memory foam is soft, springy, and supportive. The hybrid nature of this mattress means orthopedic support doesn't come at the cost of comfort. As a special addition to the Emerald, we placed a layer of Cool Marble Foam - memory foam that's 20x more breathable than other memory foams! Providing the same premium degree of support but holding slightly less heat, the Emerald is perfect for those who prefer a slightly cooler night's sleep. Enclosed in a premium velvety zip cover - washable, so keeping clean is easy. Manufactured in the UK to the standards of the National Bed Federation, using CertiPUR-certified foam, you can (quite literally) rest assured on your Pureflex mattress; knowing it is free of heavy metals and harmful dyes. Naturally resistant to mildew and dust mites, our foam is hypoallergenic and a great choice for asthma sufferers. When we package our mattresses, we compress them with more than 10,000 pounds of force per square inch. That's more force than an elephant standing on your foot! We do this to keep the package small and the shipping cheap - and we pass that saving on to you.

The hybrid nature of this mattress means orthopedic support doesn't come at the cost of comfort! As a special addition to the Ruby, we sandwiched the 4G Revo visco-elastic memory foam between two layers of the most advanced bedding material on the market: Gel-flex! A revelation in material chemistry, Gel-flex is composed of the same polymers in memory foam - only bonded to a gel-like material, bringing a new dimension of comfort. The memory foam polymers use your body heat to morph; supporting every inch of your body with limited motion transfer. The Gel-flex technology then dissipates that heat - keeping you cooler than standard memory foam. The apex of breathable, cool comfort, we're especially proud to use Gel-flex in the Ruby.
