Any simple shed plans using mattresses as insulation? Answered

there are so many free mattresses out there, which would be great for wall insulation, but im trying to figure out a simple method for building walls that will fit them and still be able to attach the drywall/plywood. plus i dont want the walls to be much thicker than the mattresses are already.


I agree with mikeasaurus that you should take the springs out as they offer little value as insulation other than air space. Sheds smaller than 10x10 can be built 24" on center. Take the material on hand and put it between the studs. I have used my own old funiture for many things. Pillows, window insulation, cusions for stools, I even made a vest out of an old leather recliner. Watch out for "found" mattresses. The number one problem with them is urine, number two, cockroaches. Wash the cloth parts and disinfect the others with Lysol or something. A couple of days outside in the sun in a black trash bag may drive bugs out. Loosely pack the stuff in between the studs then drywall. if the material tends to sag try stapling it to the studs, if that doesnt work it may not be a good choice for vertical insulation so use it on the ceiling.

Also don't forget that mice nest in old mattresses stored outdoors or in sheds.

There's a few issues here: Mattresses may have the elements to make good insulation, but as they are they will not do much for you, however if you were able to shred them they would produce a batting insulation with a much higher R value (which means better insulation). Building then into a wall will mean the your wall thickness will be somewhere in the area of about 9"-12", which is incredibly thick for a wall assembly, especially since the R value of a mattress as is will be relatively low. The best method to attack this idea is to rip open the mattresses and remove all metal springs and ribs, then shred the fabric and mix it with fiberglass insulation or whatever materials you desire (really you need another ingredient which has a high R value). Then you can simply use it to fill any voids you have in your wall. Really this is a time consuming method which may produce results that you are not happy with, however this is your best bet if you are looking to make a contribution to recycling with mattresses. An interesting idea though, I'd love to see any data you have and if you go through with it you should definitely post it up here! Good luck!
