Advanced lumbar support: the ErgoAlign Contour Layer helps alleviate tightness and discomfort.
Innovative GlacioTex Cooling Cover feels instantly cool when you get into bed, for that crisp-sheets feeling.
Peaceful nights for you and your partner thanks to a microcoil comfort layer that erases any shifts or stirrings.

Why is the Twilight Elite the best mattress for side sleepers?
The Helix Twilight Elite is our highest-end mattress for side sleepers who love a firm mattress and want the best of the best for their sleep. Not only is it designed by sleep scientists with extra contouring to the hips and shoulders, it also includes our exclusive SupremeSupport 7.0 Ultra-Dense Memory Foam, made in-house at our Arizona facility with an extremely rare 7 lb. density for unmatched comfort that calms and relaxes the body. A layer of cradling microcoils provides stability, support, and enhanced motion isolation so couples don’t wake each other in the night.

Learn more.
Does this mattress require a box spring, foundation, or a particular base?
Yes, you need a support system under your mattress. We offer a few options that properly support your mattress: the Foundation, Adjustable Base, and Bed Frame. If you prefer to use something different, we recommend using a bunkie board with a box spring, or any support system with a firm, flat surface and thick slats no wider than 5.5 inches apart, which can cause sagging and void your warranty.
How do I choose a support base?
Because this is a hybrid mattress, it's important to provide your mattress with the right support beneath its foam layers. Using your new mattress without the proper support can impact the way it feels while you sleep and in some cases can even void your mattress warranty. As you decide between different support bases, it can be helpful to consider:
How tall do you want your bed to be?
How much under bed space are you hoping for?
How will your support base look next to the rest of your bedroom furniture?
