What Sleep Number® Owners Say About Our Replacement Foam

Rated 4.9 across 180+ Google reviews

Was able to replace the foam in a 10+ year old Sleep Number bed and make it as good as new — at a fraction of the cost.

Ordered replacement foam for a bed no longer serviced by Sleep Number. Easy to order off the website and it came in no time. Fit perfectly. Saved big over replacing the whole mattress — couldn't be happier.

Upgraded my old Sleep Number bed with a new cover and memory foam. Half the price of what it was from Sleep Number, and a great product.

My husband ordered the firm foam and it was too hard for me. I called and the rep explained all the foam options and helped us land on medium. Their customer service is top notch — if you are not sure which foam to buy, give them a call and let them walk you through it.
