Sofa Sleeper Size & Dimensions: what is the size of a sofa bed?

What are sofa sleepers, and why are they crucial for comfort? A sleeper sofa is a sofa that can be converted into a bed by pulling out the mattress. The standard sofa sleeper size is for a queen sofa bed mattress 60 by 72 inches, a full sofa bed mattress 52 by 72 inches, and a twin sofa bed mattress 35 by 72 inches. The mattress can either pop out or fold out and is typically hidden (skip straight to the Sofa sleeper full size chart).

A sleeper sofa’s comfort and design can vary, and the mattress can be anything — from an inflatable to a Tempur-Pedic.

This is one of the most useful furniture you can have, regardless of whether you refer to it as a sleeper sofa or a sofa bed. If you have limited space, one solution would be to use a sleeper rather than a sofa in your living area.

Living in a small apartment enables you to convert any space into a guest room or even a room for yourself.

Choosing which size to start shopping in may be the first step to discovering your ideal sleeper. Dimensional ranges between one size and the next-closest alternative frequently overlap. The size of the mattress inside a sleeper sofa determines its size. 

Any given sleeper sofa’s dimensions will mostly depend on two elements. Of course, the size of the beds inside will come first. The type of your sofa will determine its size after the size of the mattress, as it will have a slightly smaller footprint than a sofa with a larger arm.

Don’t just measure the length or width of a couch sleeper because that won’t give you the entire picture, and the measurements may be off. The proper way to measure is as follows:

  • Since the arm-to-arm of the sofa is often where it is the widest, measure that distance.
  • The height measurement comes next; measure the back at its highest point.
  • One of the most crucial dimensions to make is the sofa’s depth.
  • The sofa sleeper’s diagonal depth must be measured next. You can measure with straight tape from the top rear to the bottom front of the frame.

How much space you have depends greatly on the size of the sofa sleeper you need. Have a compact area? Your best bet is a twin bed. A twin sofa bed is small but useful. It features a modern, elegant bench-style couch that is quickly convertible to a bed.

We advise selecting the largest sleeper mattress if you have extra space. For guests, the most comfortable option is a queen sleeper sofa. Standard queen-size sleepers or reversible chaise sleeper sofas are your finest options if you want the greatest queen sleeper.

You may adjust these functional, fashionable components to suit your needs by pulling out the bed and moving the chaise ottoman to one side or the other.

A two-piece sleeper sectional is also an upgrade option, albeit some couch beds only come with a full-size mattress.
