Our Finest Custom Latex Mattresses


100% Natural Talalay Latex Mattresses

When only the best will do, our much in demand Nu-Lex Natural Talalay Latex mattresses can always be sized for European bed frames, RV, yacht or other custom sized mattress needs.

Often custom mattresses have limitations on thickness, particularly for RVs and boats. Not only can we build the Nu-Lex to fit these size restrictions, we can also layer the latex in a custom Nu-Lex to create added support for adults in a thinner natural latex mattress.

Pricing for a custom Nu-Lex is very reasonable, please call us at 1-800-255-0181 for more information. When a Nu-Lex mattress will be covered with upholstery to match your RV or boat, we can simply supply the latex.
