A sleeper sofa is a couch with a fold-out mattress that tucks away behind the cushions during the day. This style is perfect for households that often have overnight guests but might lack a spare bedroom. Even if your home does have a formal guest bedroom, there may be occasions when you have more guests than beds. Great for slumber parties and family gatherings, sofa beds are both kid- and family-friendly. Remember to get extra bedding to make your guest’s stay more inviting.
