Well, the provided search results are about as helpful as a screen door on a submarine, offering up a smorgasbord of navigation links but zero actual dimensions. Fear not, because the answer to your question is delightfully variable.
Asking how wide a sofa sleeper is is a bit like asking "how long is a piece of string?" The width of the sofa itself depends entirely on the size of the mattress it's hiding within its cushions. Think of the sofa frame as the fancy gift wrap and the mattress as the actual present.
Your most common option is the queen-size sleeper. These are typically found in standard three-seat sofas and usually range from about 75 to 95 inches wide, arm to arm. This is the go-to choice for hosting a couple you actually want to be comfortable.
Stepping down a notch, you'll find the full-size sleeper, which often lives inside a larger loveseat or a small sofa. These generally measure between 65 and 80 inches wide. They're perfect for one person to sprawl out or for two very close friends.
For smaller spaces, a twin sleeper is a fantastic solution. These are often disguised as oversized chairs or small loveseats and can range from 50 to 65 inches in width. It's the ideal spot for a single guest or your nephew who's obsessed with video games.
Just remember, the overall width is heavily influenced by the style. A sofa with huge, puffy, rolled arms will be significantly wider than a sleek, modern one with thin track arms, even if they both contain the same size mattress. Always check the specific product dimensions before you fall in love.
