Tell me about 120 Night Comfort Guarantee?

If, after sleeping on any new mattress for the required 30 nights minimum (to allow time for your body to adjust to a new mattress), you are not satisfied with the mattress, it may be exchanged for up to 120 nights after delivery. This is a one-time exchange for the same size mattress only, and there are no refunds. You will receive full credit of what you spend on the mattress only towards another mattress in the store. There is a mandatory $100.00 re-delivery and pickup charge for the exchange. Stained, damaged, clearance, floor model, foundations, power bases, are not covered by our exchange policy, all sales are final.
