Foundation questions, answered.

How do I choose the right foundations?
Check your mattress manufacturer’s support requirements and your bed frame’s dimensions before ordering. Add the frame, foundation, and mattress heights to estimate how high the finished bed will sit. Our team can help you check the fit at our contact page.
Does the 120-night mattress exchange apply?
The comfort exchange covers eligible mattresses, not pillows, bedding, toppers, protectors, foundations, or other accessories. Confirm the applicable return terms before purchase at 120-night guarantee.
What warranty comes with a foundation?
Warranty terms vary by brand and model; each product page lists the term when the maker states one. Keep your receipt and product labels. Find help with a claim at warranty coverage.
How can I check delivery or local availability?
Delivery options depend on your address, order, and selected item. Contact the showroom before visiting to confirm that the model and option you want are available. See our stores at showroom locations and delivery information at delivery details.
Do I need a box spring?
You need the support system specified for your exact mattress. That may be a suitable platform, rigid foundation or approved adjustable base. A decorative frame with open rails does not automatically provide a sleeping surface. Ask our team about an old box spring or foundation when you schedule. Compare box springs, rigid foundations, platform beds and bunkie boards.
What does delivery and setup include?
Options depend on your address and order. Our team sets up the products we deliver. Tell us about stairs and access when arranging delivery. See the delivery & setup details.
