About Our King Mattress Collection
A king mattress is one of the largest and most widely available sleeping surfaces, measuring 76 inches wide by 80 inches long. Queen mattresses are the preferred choice for master bedrooms where space and sleeping comfort are both priorities.
A king-size mattress offers the ultimate comfort in a shared sleeping space, providing 16 inches of extra width compared to a queen. That extra room gives each partner about 38 inches of personal sleeping space, roughly the width of a twin XL mattress, allowing both sleepers to stretch out, change positions comfortably, and enjoy a more restful night's sleep with fewer disturbances.
At Cloudy, our mattress collection spans every major brand, construction type, and comfort level, from memory foam and hybrid designs to pillow-top and innerspring options. Whether you are searching for a king memory foam mattress for motion isolation, a king hybrid mattress for balanced support, a plush king-size mattress for luxury comfort, or a medium-firm king-size mattress for consistent spinal alignment, our collection has the right option for every budget.
What to Look for in a King Mattress
Here is what you need to look for in a king mattress:
King Mattress Dimensions
It is also known as an Eastern king and measures 76 inches wide by 80 inches long. This is the same length as a queen but 16 inches wider, providing significantly more shared sleeping space for couples.
Mattress in a Box
Most mattresses in our collection are available in a compressed bed-in-a-box format for standard home delivery. However, white-glove delivery and setup are also available on qualifying mattress orders.
Split King Compatible Models
For couples who want independently controlled adjustable bases, split king configurations use two twin XL mattresses side by side rather than a single king. Our collection includes mattresses available in twin XL sizing for this purpose.
Motion Isolation
Memory foam and hybrid mattresses come with individually wrapped coil systems that provide the best motion isolation in this size, preventing a restless partner's movements from disturbing the other side of the bed.
King Pillow Top
Plush king pillow-top designs deliver the deepest surface cushioning available in a king size, ideal for side sleepers or couples where both partners prefer a softer feel.

Who It's For
This mattress category is perfect for:
Couples Who Want Maximum Space
The king size provides each partner approximately 38 inches of personal sleeping width. For couples who value ample personal space at night, the king is the most practical standard size.
Couples With Pets
This mattress is the most practical size for couples who share their bed with a pet, providing enough total surface area to accommodate an animal without reducing either partner's personal sleep space.
Master Bedroom Upgrades
For homeowners with a bedroom of 12 by 12 feet or larger, upgrading from a queen to a king is the easiest space upgrade available without any structural changes to the room.
Back Pain Sufferers Who Share a Bed
The extra width makes it easier to change positions throughout the night and reduces disturbances caused by a partner's movements. If one sleeper experiences back pain, a king mattress works well with split king adjustable bases or mattress toppers, making it easier to customize comfort for one partner.
