If you have antique or custom furniture we want to make sure that your new bed will fit.
For beds and adjustable bases we recommend rubber caster cups to place underneath each bed leg.
If the slats on your bed frame are further than 2 inches apart we recommend laying a bunkie board inside your bed frame to create a solid surface for your sleep number mattress.
Hi george i urge you to replace the box spring regardless especially if what you have is 7 10 years old or older.
You don t have to follow any rules in the bedroom except your own so it s as ok to leave your box spring and mattress on the floor as it is to mount your bedding into a conventional bed frame.
