Wyoming King Mattresses

Wyoming King is not a type of mattress, it is a size: 84” x 84”, or 7’x 7’.  We make these oversized mattresses here at Von Viva, in several varieties actually (see our four models above), along with many other large sizes. We sometimes joke with people that the further north you go, the bigger the mattress:  California King is big, Wyoming is bigger, Alberta is bigger still, and Alaskan the biggest   In addition, there are numerous customizable options available, so you can truly make your Wyoming King suited to you.  We can also supply custom-built beds and bed linens.

Wyoming King vs. California King

The state of California is a lot bigger than the state of Wyoming, but when it comes to mattresses, the Wyoming King (84”x 84”) wins at 12” wider than a California King (72” x 84”). Perhaps it is the colder winters of Wyoming that made families need a bigger bed to huddle together in. For reference, see this mattress sizing chart:

At Von Viva Mattresses, founded in 1976, we meticulously design and build made-to-order premium Wyoming King, California King and other oversized mattresses, shipping them straight from our workshop to your door.  We do not use warehouses or retail middlemen.

How do we produce such large mattresses?  Using our own industry-leading luxury modular mattress design, making the mattress very easy to assemble and disassemble without any tools required.  This means they pack conveniently, and fit through doorways and around corners; it also means the segments of the mattress can be completely tailored for materials, firmness and comfort:


Advantages of our Wyoming King’s modular design

  • The mattress can accommodate two (or more) sleepers instead of one; for example, firm on the left side, medium on the right – with a completely seamless experience at the surface.
  • Certain Wyoming King mattress models (such as our Kona, Denali and Rundle) also allow different comfort preferences vertically, e.g. medium in the shoulder region, and soft in the hips.  And yes, vertical preferences are also customizable for each sleeper.
  • The Wyoming King’s components can be flipped and rotated for superior longevity.
  • We use a variety of fine, natural materials: Organic Talalay Latex, Dunlop Latex, Joma Wool, Organic GOTS Cotton, as well as the finest quality plush-synthetics. 
  • We include a personal phone consultation with each mattress, to ensure it is a perfect fit for your needs before its construction begins.
  • Because components can be easily replaced over time as they wear (see our components page), your luxurious Wyoming King mattress is ultimately a lifetime product.

Shipping:  We offer free shipping across North America (including Wyoming!), based on typical shipping allowances. We firmly wrap and pack our mattresses into layers of cardboard and fabric, to ensure their safe delivery.  Our modular mattresses quickly disassemble and reassemble, making them easy to move through doorways and ship safely.  For more shipping information click here.

Warranty: Have you ever tried to return a mattress purchased from out of town?  It is nearly impossible to pack and ship. That’s why at Von Viva, we offer replacement components instead, at far less than the cost of an entire mattress. While our premium quality mattresses will typically last 8 – 15 years without refurbishment, we offer components here that also include shipping fees.  Click here for more details on our warranty.
