Building an insulated mattress from salvage life jackets' foams
With the winter arriving on Lesvos island, it was decisive to propose a solution to the cold infiltration inside the tents. In addition to the wooden pallets, this insulated mattress enables to improve insulation from the ground.
Made from life jackets' foam which can be easily fund here, these mattresses permit to disminish the material pollution on the island. The survival blankets and plastic tarpaulin wraping the mattress, even if not coming from salvage, enable to improve the insulate and waterproof aspects of the mattress against humidity. Facing the emergency of the situation and the time imperative, we could not sew an insulating tarpaulin, which for example could have been made with the inflatable dinghy's fabrick stored on the island .
Life jackets foam
2 survival blankets
Plastic tarpaulin (could be replaced by a sewed tarpaulin made from inflatable dinghy's fabric )
It consists of removing the foam inside the life jackets using scissors or an utility knife.
To assemble the pieces, use the heating gun to melt a little bit the foam before sticking it on another piece of foam. The goal is to achieve some kind of foam patchwork with the size wanted
For example it is possible to realize a big mattress covering entirely the floor of a tent.
To insulate the foam at best, you need to roll it using survival blankets. So as to do that, use adhesive tape to attach the blankets on both sides of the foam.
"NB: It is better to use the aluminium side on top so as to reflect the body's heat."
Cover the whole mattress with a plastic tarpaulin to avoid water and humidity to penetrate inside. Attach it again using adhesive tape.
The mattress is above the wooden pallet and the tent canvas. Foldable and pretty light, it can be transported easily.
It is also possible to 'stick' the foam pieces together with straps made from cutting plastic bottles (in slices) and using them as some kinds of laces mainting all the pieces together with small holes that you need to do in advance.
