A pullout sofa bed normally has a very thin mattress. Because the mattress is so thin, the metal construction of the bed’s support is felt through the mattress and this makes for a very uncomfortable night’s rest. The following methods list the most effective way to make modern or rustic sofa beds more comfortable.
1) Add layers to the mattress before anyone lies on it.
2) Use a liner between the mattress and the springs.
3) Combine both 1) and 2) to offer the most comfortable mattress.
By adding layers of padding to the mattress, it becomes softer and more supportive. Add a layer of textured foam and then an extra thick mattress pad on top of that. The layers of padding will make it impossible to feel any of the inner workings of the mattress mechanics. Add these layers just before putting on clean sheets and offering the bed to guests. The extra thickness may prevent the bed from closing back into the sofa. Remove the extra layers before folding the bed back into the sofa.
The layer of foam may be sufficient to provide the comfort needed if it is at least 5″ thick or more. If the foam is thinner, try adding a heavily quilted mattress pad as well. The extra polyfil in the pad may feel even softer than just adding a foam liner.
The other option is to separate the mattress from the offending metal support. Use a plywood sheet to cover the metal support and then add the mattress on top. It would be difficult to store a plywood sheet big enough for a full-size mattress, so you need to be crafty and construct a folding plywood liner. Make sure you cut the plywood in three equal horizontal pieces held together by two strips of two inch wide heavy weight muslin. Glue each strip on the two edges of plywood panels until you have a folding plywood panel that you can lay on the metal bed support to shield the mattress from the metal support’s digging impressions.
The last solution is to try adding foam, an extra thick mattress pad and a plywood liner. The night’s rest is sure to be comfortable with all these precautions used. No matter which method you utilize, the mattress will offer a much greater improved comfort level.
