A double bed is typically designed to accommodate two people, but how many people can actually sleep in it comfortably? According to the National Sleep Foundation, a standard double bed is about 54 inches wide, which is roughly the same width as two single beds pushed together.
Most double beds can fit two average-sized adults with some space to spare. The American Academy of Sleep Medicine recommends a minimum of 30 inches of width per person for comfortable sleeping. A double bed typically provides about 27 inches of width per person, which is still within the recommended range.
However, if you have larger or taller individuals sleeping in the bed, you may find that it's more cramped than you'd like. The average height of an adult is around 5 feet 9 inches, so if you have someone much taller than that sleeping in the bed, you may need to consider a larger bed size.

What is a Double Bed

A double bed is a bed that is typically 4ft 6in wide and 6ft 4in long.
This size is suitable for most adults to sleep in and provides a reasonable amount of space for two people.
The size of a double bed can vary from country to country and region to region, so you need to be aware of the exact specifications of the size when choosing one.
Double beds are usually around 137cm wide and 193cm long, which is a standard size that many people are familiar with.

Return
I've found that a standard double bed is primarily designed to accommodate two adults, making it an ideal choice for couples.
A double bed can still cope with the occasional addition of a child, but it's not suitable for three people on a permanent or regular basis.
In my experience, sleeping with a third person in a double bed can be quite uncomfortable, especially if you're all trying to get a good night's sleep.
Theoretically, it's possible to squeeze in three adults, but this can have a serious impact on sleep quality and comfort.
