Designed to fit box springs, flat platforms, adjustable and slated frames, Allswell’s hybrid mattresses, a combination of memory foam and individually wrapped coils, deliver high quality at affordable prices.

The entry-level 10-inch Allswell, at just $265 for a twin, features the brand’s signature quilted top panel, cooling charcoal and copper gel-infused memory foam and individually wrapped coils that help keep motion transfer from happening. The 12-inch Allswell Luxe Hybrid adds edge support and an advanced cooling gel swirl foam. For those who like a firmer mattress, the 12-inch Brick is a great option, with a firmer top foam layer for added support. And the 14-inch Allswell Supreme, the brand’s premium design, features a Euro top, reinforced edge support, a temperature-controlling foam layer and handles.

The company offers free shipping, a 100-night risk-free trial and a 10-year limited warranty — and, in addition to bed frames, toppers, linens and decor, it also sells crib mattresses.

A favorite among athletes, Bear mattresses are designed with the environment in mind and Celliant technology that the company says “harnesses your body’s natural energy to expedite recovery times and overall well-being.” Bear says its mattresses are clinically proven to promote your most restful sleep, help you wake up with more energy and keep you cool all night long. Not sure what Celliant technology is? According to Bear, Celliant “is the most established and clinically tested infrared textile in the industry,” which helps to regulate your body’s temperature and enhance tissue oxygen levels, which in turn can improve athletic performance.

It’s no wonder athletes turn to this bed-in-a-box company for a good night’s sleep.
