Warranty Information

Our products are sold without manufacturer warranties.

Traditional mattress retailers markup prices significantly—often by hundreds or thousands of dollars—to cover the cost of extended manufacturer warranties and replacement programs.

At Kumfy Sleep Furniture, we bypass these inflated margins.
By sourcing 100% authentic, brand-name overstock items and offering them directly to customers without manufacturer warranties, we are able to provide luxury sleep products at deeply discounted prices.
