Zoned Support™ is engineered to keep your spine in ergonomic alignment by providing support where your body needs it most, with firmer foam under the hips, waist, and lower back. Zoned Support Max™ combines our firmer center foam with a second layer of precisely cut channels to cradle the natural curve of your body while adding support to your hips, waist, and lower back for the ultimate ergonomic relief with our hybrid memory foam design.

A mattress in a box is a mattress that’s compressed in an air-sealed bag and rolled tight so that it can fit into a box that’s easier to maneuver than a traditional mattress. Allowing you the flexibility and convenience of picking your mattress online and having it easily delivered to your door.

When you receive the mattress, all you’ll need to do is pull it out of its packaging, lay it flat on your bed frame or floor, and let it expand.

Foam and hybrid mattresses can be slept on almost right away but may take up to 48 hours to expand fully. Our Snow mattresses are primarily made with memory foam and can take up to 72 hours to expand fully.

Not quite. Both bed foundations and box springs provide a base support layer for any mattress type. However, box springs add a little extra give and increase breathability, while foundations are for overall support.

A box spring is any wood or metal bed frame containing coiled springs covered by cloth. This once-popular design is now mostly found on older beds.

A foundation is any non-spring bed base, from metal or wooden slats to solid platforms. Slat models, often referred to as slatted foundations, provide more air circulation and flexibility, while solid bases give the firmest support.

Both slats and solid foundations are an ideal box spring alternative for better mattress protection.
