What Is a Colorado King Mattress? Size, Fit, and FAQs Explained
If you’re wondering “What Is a Colorado King Mattress” and how it compares to standard sizes, you’re not alone. This oversized mattress dimension has become more popular among people who want extra space to spread out beyond a traditional king.
Below, you’ll find clear answers about what a Colorado King is, how big it is, and whether it might suit your room, sleep style, and bedding needs.
What Is a Colorado King Mattress?
A Colorado King mattress is an oversized king bed that is both wider and often longer than a standard king. While dimensions can vary slightly by manufacturer, a commonly used size for a Colorado King is:
- Width: about 84 inches
- Length: about 84 inches
That makes it roughly 7 feet by 7 feet, creating a large square-shaped sleep surface.
In simple terms, when people ask “What Is a Colorado King Mattress”, they’re usually trying to understand how it compares to a standard king (76" x 80") or California king (72" x 84"). A Colorado King offers more width and more length than either of those, making it a popular choice for extra spacious bedrooms.
How Does a Colorado King Compare to Other Mattress Sizes?
Here’s a simple look at how a Colorado King stacks up against a few familiar sizes:
| Mattress Size | Approx. Dimensions (W x L) | Notes |
|---|---|---|
| Queen | 60" x 80" | Common for couples |
| King | 76" x 80" | Wider than queen |
| California King | 72" x 84" | Narrower but longer than king |
| Colorado King | 84" x 84" | Wider and longer; very spacious |
Because of this extra surface area, a Colorado King can feel noticeably more generous, especially for:
- Taller sleepers who need more legroom
- Couples who like extra distance or spread-out space
- Families who occasionally share the bed with kids or pets
Why Do People Choose a Colorado King Mattress?
A Colorado King is mainly about space and comfort options, not about special materials or technology. People are generally drawn to this size because:
- More elbow and legroom: There’s room to stretch without feeling crowded.
- Flexible sleeping positions: Side, starfish, or diagonal sleeping often feels more comfortable on a large square bed.
- Shared sleeping: It can better accommodate multiple sleepers, such as partners plus a child or pets.
However, it also takes up a significant amount of floor space. For many, the key question is whether the benefit of extra room is worth the space trade-off in the bedroom.
What Should You Consider Before Getting a Colorado King?
1. Room Size and Layout
A Colorado King can dominate a small or even medium-sized bedroom. To avoid a cramped feel, many people find it works best in larger rooms where there is still space left for:
- Walking paths around the bed
- Nightstands and dressers
- Doors, closets, and windows to open comfortably
It can help to measure your room and sketch where the bed and furniture would sit before committing.
2. Bedding and Accessories
Because the Colorado King is an oversized, less common dimension, bedding can be more limited:
- Sheets and protectors: You’ll typically need size-specific or custom bedding.
- Bed frames and bases: Standard king frames usually won’t work; you’ll likely need a frame made for this size.
- Headboards and foundations: Check measurements carefully to ensure proper fit.
This is one of the most practical concerns for anyone asking “What Is a Colorado King Mattress”—it’s not just the mattress, but also the supporting pieces and linens.
3. Mobility and Installation
An 84" x 84" mattress can be heavy and bulky. Consider:
- Stairways, tight corners, and elevators
- Whether the mattress can flex or be delivered in a box
- How easy it will be to rotate or move the bed later
Some people prefer split foundations or modular bases to make handling easier.
Is a Colorado King Mattress Good for All Sleepers?
A Colorado King is about size, not a specific comfort level. Just like other mattresses, it can come in a range of:
- Firmness levels
- Materials (foam, hybrid, etc.)
- Thicknesses
Who it tends to suit best:
- Tall sleepers who often find their feet hanging off smaller mattresses
- Couples who want more individual space without separate beds
- Families who casually co-sleep or lounge together
Those who may not find it practical:
- People with small bedrooms
- Anyone who prefers simple-to-find, standard bedding
- Those who move often and want easier transport
How Does a Colorado King Differ From Other “Big King” Sizes?
You may see other oversized terms like Wyoming King, Alaskan King, or Texas King. Each has its own approximate dimensions, and they are not standardized across all makers.
The main takeaway:
- A Colorado King sits among these oversized square or near-square options, usually smaller than the very largest options, but larger than a standard or California king.
If exact dimensions matter to you, it’s important to verify measurements rather than relying just on the name.
