Frequently Asked Questions
How hard is the base to assemble?The base should only take about 10-15 minutes to assemble. No tools required!
Should I replace my old box?We recommend it although many times an old base is still fine. Our bases however offer more support than many older foundations. Many people just want to refresh their entire sleep system.
Will it fit up and down my stairs?Absolutely. Our bases all come completely boxed up, so narrow stairwells are no problem.
