King Mattresses

What Is a King Size Mattress?

A king size mattress measures 76 inches wide by 80 inches long, making it the widest standard mattress size available. It provides each partner with 38 inches of personal sleeping space — more than a twin bed — making it the ultimate choice for couples who want maximum room to spread out. At LA Mattress Stores, we carry a premium selection of king mattresses from Tempur-Pedic, Stearns & Foster, Sealy, and Diamond Mattress — all available to try in person at our five Los Angeles locations.

With over 110,000 monthly searches for "king size mattress," it's one of the most in-demand mattress sizes on the market. Whether you're shopping for a standard king or a California king mattress (72" × 84"), which is narrower but longer for taller sleepers, our showrooms have both options in every mattress type and firmness level.

Benefits of a King Size Mattress

Upgrading to a king mattress transforms your sleep experience. Here's why so many couples and individuals choose a king:

• Maximum Personal Space: Each partner gets 38 inches of width — 8 inches more than on a queen mattress. That extra space significantly reduces partner disturbance and allows for unrestricted movement during sleep.
• Family-Friendly: A king mattress provides enough room for couples who share the bed with children or pets on occasion. There's space for everyone without sacrificing comfort.
• Luxury Feel: A king bed creates a luxurious focal point in your master bedroom. The generous dimensions make the entire room feel more like a suite than a standard bedroom.
• Better Sleep Quality: Studies suggest that couples sleep better with more personal space. A king mattress reduces the frequency of partner-related sleep disturbances including movement, heat transfer, and blanket-stealing.
• Adjustable Base Compatible: King mattresses work with split king adjustable bases, allowing each partner to independently adjust their head and foot elevation. This is the ultimate setup for couples with different sleep preferences.

How to Choose the Best King Mattress

When shopping for a king size mattress, these factors will help you narrow down the best option:

• Standard King vs. California King: A standard king (76" × 80") is 4 inches wider but 4 inches shorter than a California king mattress (72" × 84"). If either partner is over 6'2", a Cal king's extra length is beneficial. Otherwise, the standard king's extra width is more useful for most couples.
• Room Size: You'll need a bedroom at least 12' × 12' to fit a king mattress comfortably with nightstands and walking space. Measure your room before committing — our team can help you determine if a king will fit your space.
• Mattress Type: Hybrid king mattresses are popular for their combination of support and cooling. Memory foam kings provide maximum pressure relief and motion isolation. Latex kings offer natural materials and responsive bounce. We carry all types in king size.
• Weight and Delivery: King mattresses are significantly heavier than smaller sizes (often 100–150 lbs). Our free white glove delivery service handles all the heavy lifting — we'll deliver, set up, and remove your old mattress at no extra charge.
• Split King Option: If you and your partner have very different firmness preferences, consider a split king — two twin XL mattresses placed side by side on a split king adjustable base. Each partner can choose their own firmness level and adjust their side independently.

King vs. Queen Mattress: Is the Upgrade Worth It?

A king mattress provides 16 additional inches of width compared to a queen (76" vs. 60"). That's the equivalent of adding another person's worth of shoulder space to the bed. Couples who report poor sleep on a queen due to feeling cramped, partner movement, or different sleep schedules almost always benefit from upgrading to a king. The tradeoff is cost (king mattresses and bedding are 15–25% more expensive) and space requirements (your bedroom needs to be at least 12' × 12'). If your room can handle it, the upgrade is absolutely worth it for most couples.

King vs. California King Mattress

The California king mattress (72" × 84") is the longest standard mattress available, designed for taller sleepers. It's 4 inches narrower than a standard king but 4 inches longer. For couples where one or both partners are over 6'2", the Cal king prevents feet from hanging off the edge. For everyone else, the standard king's extra width provides more usable sleeping space. Both sizes are available in our full range of brands and mattress types.

Single-piece king adjustable bases are also available. Visit our adjustable bed collection to find the right pairing.

Will a king mattress fit through my door?

Standard interior doorways are 32–36 inches wide, and a king mattress is 76 inches wide. Our delivery team is experienced at maneuvering king mattresses through tight hallways and doorways by compressing and angling the mattress. Bed-in-a-box kings arrive compressed in a box that fits through any standard doorway. If you're concerned about access, our team can assess your entryway before delivery.
