The only way to truly get total waterproof protection from a mattress cover or padding pad is with a waterproof lining or waterproof membrane on a pad or cover. But it is even more important that you pick the correct waterproof covering, as most waterproof mattress covers available are typically made out of different types of plastics.
Many waterproof plastic protectors are made from vinyl, but this plastic is not the most suitable type of plastic for a waterproofing bedding pad. Most waterproof mattress covers are made out of a combination of vinyl and polyester. While both of these are fine waterproofing materials, they are not quite as durable as either vinyl or polyester.
A better choice would be to look into a waterproof plastic that is made out of a high-quality polyester, which is a much better choice than vinyl or polyester that is made out of cheaper plastics. In addition, waterproof plastic covers are often made with higher quality fabrics to prevent tearing and cracking, something that can happen when you wash it. You should also avoid some cheap waterproof plastic covers that are not as durable as the more expensive plastic. Some of these cheaper waterproof plastic covers will tear very easily and won’t last long.
You should also try to get waterproof plastic that is machine washable if you can. If possible, you want something that is stain resistant. This will save you from having to constantly scrub and clean your waterproof plastic cover. You can also check your local mattress store or online retailer if there are any waterproof mattress covers that will fit your mattress. You may even find that there are a number of different waterproof plastic covers available.
You can even make your own waterproof plastic cover, but this is not recommended. As with any DIY project, you are much better off getting a waterproof mattress protector that is already made and tested so you don’t have to worry about having to fix anything. You can even go the extra mile and get a waterproof liner for your waterproof plastic cover, but this might be a little more work and can sometimes be more expensive.
The best way to ensure that your waterproof plastic covers stay on the cover is to make sure that they are properly stitched, and to make sure that they are properly washed. After washing, lay them back in the laundry and let them air dry completely before placing them back on your bed.
