What to Know Before Buying a Clearance Mattress
Clearance mattresses at National Mattress include open-bag items, showroom floor models, factory demo units, and discontinued collections from brands like Serta, Sealy, Beautyrest, and Tempur-Pedic. Every item is inspected and clearly labelled with its condition, whether that is original packaging opened for handling, light display wear, or a cosmetic scuff that does not affect comfort or support. Compare each clearance listing for its construction, condition, any stated certifications and current savings. Read the warranty information and confirm the terms for the individual item before ordering.
Focus on three things when shopping clearance: firmness match (our selection spans extra firm to plush), mattress type (euro-top/pillow-top, memory foam, hybrid, and tight-top styles are all available), and size availability, clearance stock is limited, so once your size sells out it typically does not restock. Not sure which type suits your sleep style? Our mattress selector quiz narrows the options in under two minutes.
