Wyoming King Bed Frame
By month three with a toddler sleeping sideways across a king mattress, one of you is sleeping at the edge most nights, telling yourself it's temporary. Months go by, and the kid only gets bigger.
A Wyoming King is 84 inches by 84 inches. Seven inches wider than a standard king in both directions, with the same length as a California king. The width is what changes the math for families. At 84 inches wide, two adults plus a small kid (and maybe a dog) can each find a pocket of mattress and stay in it through the night.

Buying Tips

Frame Types That Work at Wyoming King Scale
A Wyoming King (84" × 84") is more manageable than an Alaskan King but still requires a purpose-built frame:
Platform frames
The standard choice. At 84" × 84", a platform frame is easier to source and less expensive than Alaskan King equivalents. Most sellers offer both wood and metal options.
Slatted platforms
Same 3-inch maximum slat spacing rule as larger beds. At 84" wide, center support is still important – a single center beam with legs is sufficient.
Upholstered frames
Available from Wyoming King Beds and AdultBunkBeds.com. The 7-foot width is still too wide for most doorways as a single piece, so these typically ship with the headboard separate from the base.
Adjustable bases
Some sellers offer adjustable (split) bases in Wyoming King size - Engineered Sleep and Big Mattress Co. have options. These are split down the middle so each side can adjust independently.
Standard King frames won't work
A King frame is 76" × 80" – 8 inches narrower and 4 inches shorter than a Wyoming King. The mattress will overhang on all sides.
Weight Support Requirements
A Wyoming King mattress weighs 90–160 lbs. With two adults, total load is 390–560 lbs.
Frame requirements:
- ✓Weight capacity: 800 lbs minimum, 1,000+ lbs recommended
- ✓Center support: Required – one center beam with at least 2 legs
- ✓Slat count: 12–18 slats across the 84" width
- ✓Leg count: 6 minimum (4 corners + 2 center)
The Wyoming King's square shape distributes weight evenly, which is an advantage over rectangular beds – there's no long unsupported span in one direction.
Frequently Asked Questions
Are Wyoming King frames easier to find than Alaskan King?
Slightly. The smaller 84" x 84" size means more manufacturers offer Wyoming King frames, and delivery is easier. However, they're still specialty items not found in regular stores.
