The 120-Night Sleep Guarantee is only available if you purchase the mattress only. Sven & Son® has your back for 120 nights of sleep. If you don't like it for any reason during those 120 nights (assuming you purchased only the mattress), we'll issue you a refund!
We can't offer the 120-Night Sleep Guarantee on bundle purchases because of the shipping costs and special bundle pricing, but if you're buying a bundle from us, rest easy. We stand behind our products with a free industry-leading warranty and always put our customers first. Our customer reviews here on our website as well as on Amazon speak for themselves - we take care of our customers.
