Futons are great to use as a sofa during the day and, with a great futon mattress, can serve as a bed at night. However, the bed function doesn't work out too well if the futon mattress is not suitable for sleeping. Sometimes they can be too hard, not level, or they don't offer any support at all. That is why it is important to consider during the buying process that someone just might be sleeping on this piece of furniture and it needs to allow that individual the sleep that they need in order to be productive throughout their day. Some have a misconception that it is the frame that makes the futon comfortable, but it is actually the mattress that gets the job done. It is important to know that futons come in bi-fold where the mattress is folded in half and tri-fold where the mattress is folded into thirds. Be careful when making this decision because a tri-fold is going to be thinner and not offer as much support as a bi-fold. Therefore, if the futon is going to be frequently used for sleeping, a bi-fold may be the right decision. Things to look at are: flexibility, weight, rigidity, and firmness. Lighter is good as long as it provides comfort, but heavier is good in cases of frequent use. The rigidity is going to determine how well the mattress will keep shape and of course flexibility is how the mattress will fold. Simply keep these things in mind for the next futon purchase and you'll be comfortable in no time. Mattress Next Day is probably the largest mattress superstore on the internet.
