Sometimes the best way to accommodate guests in a home is to purchase a trundle bed set, which is essentially a bed frame that features a second, pull-out frame on which another mattress can be placed. This means the bed set will feature two mattresses, one of which stows underneath the other. Choosing the best trundle bed set starts with determining your needs. Twin beds are most often made into trundle beds, though other sizes do exist. Be sure to choose the size that is right for your needs.
If you already have a bed in your spare room, you may be able to buy a trundle bed set that is independent and can be stowed underneath the existing bed frame. You will need to measure your existing bed frame to ensure you can find a trundle bed that will fit properly; if your bed is low to the ground, you will not be able to find a trundle bed that will work with your current bed frame. If this is the case, you will need to buy a trundle bed set that includes both mattresses and the integrated pull-out frame.
Choose between wood frames and metal frames. Wood frames will generally be more expensive, especially if you choose hardwoods, but the unit will be exceptionally beautiful and quite durable. If you are working with a tighter budget, you can consider metal frame trundle bed set offerings. While these are generally less expensive, they are not necessarily any less attractive, and they may be just as durable, if not more so. In either case, be sure the trundle bed itself is easy to move in and out, and make sure it can be secured safely under the bed when not in use.
Two other options you may want to consider when purchasing a trundle bed set include a pop-up trundle and a day bed trundle. A pop-up trundle is a bed that will stow underneath the top mattress, but when it pulls out for use, it will pop up so the mattress is not low to the ground. This is a great option for adults who cannot or don't want to reach down to reach the mattress. A day bed trundle features a day bed as the top mattress; this is a more versatile type of bed that can act as a sofa as well. This is a great option for a home office or other living space that is used regularly when guests are not using the room.
