A futon is a piece of furniture which is both a bed and a couch.
They are a great way to save space because when you no longer need a bed it is a simple matter to fold the futon up into a lounge.
The space saving designs make futons ideal for small apartments or offices, or when you need another bedding option when large amounts of guests stay over.
When you are looking to buy a new futon you need to first consider what you will be using it for primarily.
For example, do you want a couch that you can occasionally use as a bed when guests stay over? Or do you want a bed that will be used often but one that you can fold away during the day to save space? If you will be using the futon as a bed on a regular basis then it is important that the mattress is of good quality and that it is comfortable.
The cost of the mattress will typically increase with its quality and comfort.
The most comfortable mattress have an innerspring construction that provides great support and lasts a long time.
The cheaper futon mattresses which are made from foam or cotton only tend to sag quickly and not offer the correct amount of support.
If you will be using the futon as a couch then how comfortable the mattress is to sit on is the most important consideration.
Cotton or foam can be okay provided they are firm enough.
The frame is also another consideration.
A frame will either be constructed from wood or metal, and can come in wide variety of colors and finishes.
You should select a robust and durable frame that can easily take the weight of a heavy person.
You will also need to consider the decor of your home to ensure that the futon fits in with the overall look.
