need to find for my disabled son

[susanmomof2]

My son Carl has epilepsy plus other medical issues. Carl has a fasination with liquids. He has ruined two twin mattress and a futon mattress. To make a long story short it came to me to buy a hospital mattress for him. These mattress are waterproof, durable, and have interspring support. A regular bed is too high for carl (fall hazard if he were to have a seizure in the night) and a mattress on the floor won't last very long as he will use it as a springboard thus the need for a durable washable plastc race car bed ---he loves trains planes cars anything transportation.

Does anyone have a twin size race car bed for sale inexpensively?

Or perhaps a hospital mattress?

Or even two valences with race cars, trains, or something (not babyish) transportation themed?

Thanks

Susan
