Frequently Asked Questions
What size box spring is right for me?
The size of your box spring should match your existing bed frame or mattress. If you're shopping for a totally new set-up, the size of your bed depends on preference and if you're planning to share your bed. Queen and King sizes are the most popular for those with two people in a bed.
Is this box spring easy to assemble?
Minimal assembly is required for this folding box spring. Just unfold, attach the center support bolts, and put the cover on.
