King (76" x 80")
The best King mattresses are designed for couples who love extra space while they sleep. Great for sharing a bed with an active or very light sleeper, king size beds provide plenty of space for one person to move without disturbing the other. Be sure to measure how much floor space a king will take up before buying one.
- Designed for couples
- Good for extra shoulder room
- Works for individuals or couples
- Best for tall people over 6"2"
California King (72" x 84")
The California king size is 4 inches narrower than the standard king size, but it is also 4 inches longer over the king and queen size. Made for tall individuals and couples, this bed ensures that your feet won't hang over the edge of the bed.
Queen (60" x 80")
As the most popular size, queen size beds have the suitable width for sharing and the length for most individuals. The queen size provides adequate space for most couples without taking up too much space in the room. If you're looking for a cost-effective and space-efficient bed, the queen size is the one you're looking for.

Full (53" x 75")
Also known as a double, a full size bed is big enough for a single sleeper who wants something more spacious than a twin. Full mattresses work well for active sleepers and children/teens during their transition years.
Full XL (53" x 80")
Full XL mattresses are 5 inches longer as the full with the same width. This size works well for tall, active sleepers who want the largest size intended for single person use. Full XL models cost the same as the couple-oriented queen size model.

Twin size mattresses are the smallest and least expensive of the standard mattress sizes. The twin size works well for kids and adults who don't need a spacious sleeping surface and want extra room in the bedroom.
Twin XL (38" x 80")
Twin XL mattresses are 5 inches longer than the twin size with the same width.

This size is recommended for growing teens or tall adults looking to save space and money.
