About Replacement Mattress

Who We Are

ReplacementMattress.com is the website of Comfortable Concepts Corp., a small internet company closely tied to Walt’s Sleep Shop, which has a “brick and mortar” store along with a replacement mattress factory/warehouse in central New Jersey. Walt’s has been in business since 1955. The main players are:

Louis Leibowitz (the mattress guy) who along with his brother, David, took over the replacement mattress business 30 years ago from his father Walt, who founded it over 50 years ago.

David Leibowitz,(the other mattress guy), and Lou’s brother.

Andrew Weiss (the IT guy) is our internet business project manager. He doesn’t know nearly as much about sofa bed, RV, marine and truck mattresses as Lou and David, but is learning fast, and is always willing to lend a hand.

We stock a variety of sizes of mattresses at our warehouse in New Jersey. We also make up special sizes to order, and offer the largest selection of replacement mattresses anywhere. Our response time to an order is quite fast.

If you’re looking for high quality sofa bed, RV, marine and truck mattresses at reasonable prices, we’ve got you covered.

Any Size
We stock common sizes of sofa bed mattresses at our warehouse in New Jersey. Any other hide-a-bed mattress sizes or custom RV, marineor truck mattress sizes and shapes are made to order in our NJ factory, where we have been manufacturing replacement mattresses since 1955.

Best Quality Foam Cores
Our sofa bed, RV, boat and truck mattresses are made from high-density polyurethane foam, according to industry standards. High-density foam mattresses provide enhanced support. This is especially important with sleeper sofa mattresses—so you don’t feel the bar. If you’re looking for a firmer or softer mattress, take into consideration the IFD (Indentation Force Deflection). For more information on the density and IFD of our foam, click here.

Custom RV, Marine and Truck Mattress Shapes
Whether you need a cut corner, round cut or v-berth  for your RV, truck or marine mattress, we can make it for you in about one week. For mattress shapes that don’t fall into these categories, please contact us to discuss how we can customize it to fit your specifications.


Our sofa bed, RV, marine and truck mattresses are designed to be at their best for a minimum of 5 years. Quality materials and proven manufacturing techniques ensure that the replacement mattress will remain firm and resilient for years to come—and with our five-year warranty, you can rest easy. 

Fast, Free Delivery
Common size sofa bed mattresses are shipped the following business day (see common sizes here), while custom replacement mattresses, which are made to order, are shipped in 4-10 days.

Heavy Duty, Sewn Mattress Ticking
We pay attention to every little detail. Instead of inexpensive zip-on covers, we choose to sew on a heavy-duty mattress cover. This is one of the reasons why our replacement mattresses can be used for so many years. A sewn-on mattress ticking is especially important in sleeper sofa mattresses.  Without a well-designed and manufactured mattress cover, years of folding and unfolding the mattress will make the cover shift, resulting in a poor night’s sleep for you or your guests.

60+ Years Experience
We have been manufacturing and selling replacement mattresses since 1955.
