Recliner couches are one of my favorite things to sit on. They provide multiple angles to lounge, you could lay down if you wanted. The center has cup holders, storage, and charging ports for your phone or laptop. Also usually has 2 recliners so you and someone else can relax together.
L couches are best used for larger lounge rooms. These provide the opportunity to sit up or lay down. They also provide more seating for more people. These couches are great for families or people who like to watch tv.
Double Decker couch is what my roommates and I tried in our house. If you have a people problem and always have people wanting to watch tv or sit in the lounge. The two couches on top of eachtoher really help save room and hold more people.
This is a smaller version of the L couch just softer. This couch is super soft. This couch is great if you have a dog. The dog gets one part of the L and you get the other. Hair is also easy to clean off the couch.
