About Us

The main goal of Replacement-Mattress is to provide you with high quality replacement boat, RV and sofa bed mattresses at reasonable prices.

Any Size

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

Best Quality Foam Cores

No matter which sofa bed mattress, RV or boat mattress you choose, you can rest assured that it’s made from high density polyurethane foam, according to industry standards. High density foam mattresses generally offer a great deal of support, which is especially important in the case of sleeper sofa mattresses, in order for you not to 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 and Marine Mattress Shapes

Whether you need a rectangular, a one cut corner or two cut corner boat or camper mattress, we can make it for you especially in about one week. Such custom shapes can be easily ordered online as well. For other custom mattress shapes please contact us.


Our sofa bed mattress, RV and marine mattress types 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 will have nothing to worry about.
