How to find the best california king mattress protector

The perfect California king bed mattress protector isn’t out of reach. But before you buy, there are three criteria you should consider if you want to protect your mattress for long term use. 

  1. Make sure your mattress protector is plastic-free, or at least partially. Because who likes to sleep on a crunchy, crackly mattress all night? You can easily find protectors that are free from vinyl, PVC, and phthalates. 
  2. You should look for a mattress protector that is six-sided. If you truly wish to protect your mattress from dust, bed bugs, and liquids, then investing in a protector that covers all six sides of your mattress is the best option. Usually, these protectors are easy to slip over your mattress and zip up for ultimate protection. Nothing goes in and nothing comes out. 
  3. Make sure your mattress protector is machine washable. This is important if you want to use your mattress protector for long term use. Being able to remove your mattress cover and throw it in the wash is ideal, especially for parents of young children. You will be able to potty train and keep your mattresses!

Summary

Mattress protectors are convenient and help prolong the life of your mattress. Whether you need extra protection, extra cushion, or need help ridding your home of pests, we hope you now feel educated to make the best decision for your home.
