Custom Sized Mattresses for Extra-Long, Family Size & Oversized Beds

Now, you may wonder how such large mattresses can be shipped – in fact, we build our oversized mattresses in component sections so they can be easily boxed and reassembled by you, with no tools required. Just layer them according to our instructions, zip them tightly together, and your mattress is ready to use. We currently ship across Canada and United States.

Other major benefits of our modular oversized mattresses:

  • Your mattress can be constructed to have different levels of firmness on each side of the bed, as well as lengthwise under shoulder or hip areas. These variable components are layered under full-sized toppers and quilted fabrics to ensure a seamless, but varied structure for all sleepers.
  • If you ever move, your mattress is very easy to disassemble and move to your new home. It can fit through any small doorway.
  • Your mattress can last indefinitely because it can be flipped and refurbished. Rather than replace the whole mattress, we can simply replace the worn component at a much lower cost.

Whether your whole family sleeps together, you have pets in your bed, or you just need more room, we have the right mattress for you.

Not only can it support the firmness desired by different sleepers on the left and right sides of the mattress, but it can be zoned to vary the support along upper and lower regions along the body. These variations are created by the density of coils, material densities, and the incorporation of luxurious layers of Talalay Latex, Dunlop Latex or High-Density Memory Foam. Von Epica Empress Mattresses components can be refurbished and rotated for a lifetime of use.

The Denali has more options and flexibility than any mattress we can find in its price range.

If all-natural is important to you than this is your ultimate mattress. It has five levels of Natural Dunlop and Natural Talalay Latex that are combined in the firmness configuration for you. Latex is long lasting as is, but having a modular configuration allows you to flip, rotate and replace every component in this mattress. Each component has a cotton slip cover, and the cover is finished with GOTS cotton quilted to wool with Natural Canvas border.
