For extra waterproofing we can double wrap any size vinyl mattress

Adding a second layer of vinyl to your mattress will cost approximately 25% extra but for some end users it is worth the added cost.

It can add a second layer of protection for the inside of your mattress if the first layer gets punctured or the threads loosen over time.

It can also add a second layer of water resistance because every cover lets a certain amount of liquid through if it's left on the mattress for an extended period of time.
