It can be quite difficult finding good mattresses for sofa beds. This is because they can be quite thin and uncomfortable. A sofa bed tends to be designed to fold away, which means that it needs to be quite thin.
However, it is possible to make a thin mattress that is also comfortable and so this is why it is so important to make sure that you try out a mattress before you buy one. Just in the same way that you would, when you are buying a new bed, you should lie down on a new mattress to see how it feels. A sofa bed mattress is different to one for a regular bed but it should still be comfortable to lie on. You may also need to think about how easy it might be to move if being folded away and the weight of it and how small it can be made.
Of course, price could be a big consideration as well. If it is a mattress that you will be sleeping on frequently then it is important to think about your back and the consequences of sleeping on a mattress that is not supportive. However, if it is for a guest bed or occasional use then perhaps this consideration is not so important. It is good though, to look for good value for money. Even if you are not spending that much money or using the mattress that often, it is a good idea to try to get something that will last.
It is no good spending little money if you have to replace it really quickly. It is a good idea to go to a bed expert such as Bedstar to choose the mattress as the experienced staff will be able to advise you on exactly what would be the best for your needs.
