All sizes approximate, each bed may vary ±.5".
Deciding between a queen or king size mattress really boils down to personal choice. A queen bed is 60 inches wide by approximately 80 inches long, perfect for couples who prefer close quarters. King beds are 76 inches wide by 80 inches long, the best choice for couples that want maximum personal sleeping space. Both twin and full sizes are approximately 75 inches long, which may be too short for some adults, especially men.
Full bed recommendations: A full size bed is only enough space for a single sleeper and only if the person is shorter than 5 feet 5 inches tall. Parents are increasingly choosing full size over twin for t eenage bedrooms. Parents are even making this choice for younger children to give themselves a more comfortable place to rest when reading together at tuck-in time.
Queen bed recommendations: Queen size is a good choice for guest rooms, smaller master bedrooms and for couples who prefer close quarters. It's also a great choice for single sleepers who are also "sprawlers."
King bed recommendations: King size is the best choice for couples that want maximum personal sleeping space. It's also the best bet to accommodate that time on Sunday morning when children may pop into bed – or if the pets in your house have mattress privileges! However, size can present a problem. Even with a "split boxspring" – two twin-size foundations to support it – to make a king set more manageable, it may be too big for some bedrooms or too bulky to navigate through some corridors, doors and stairwells. It's a good idea to break out the tape measure to check your room dimensions if there is any doubt.
