Why we’ve fought for a 180-Night Home Trial and 10-Year Warranty.
9M mattresses and box springs are thrown out every yearIn the U.S. alone, 9 million mattresses and boxsprings end up in landfills every year. That’s enough to fill transport trucks from New York City to Detroit – lined up end-to-end.
The technology and materials exist to get it right the first time.Lots of companies build mattresses so you have to buy a new one every 5 years. We’re just not into that. We build our mattresses to last, and back them up with industry-leading trials and guarantees.
We want to be part of the solution, not the problem. A sneaky bonus? Happy customers recommend us to their loved ones.
Got questions? We've got answers.
