Dry Defender Heavy Duty Fitted Vinyl Mattress Protector - 9" & 16" Depths

Size (Bedding)
  • Vinyl mattress protector is made of 6-gauge vinyl
  • Fits mattresses of either 9 or 16 inch depth
  • Fitted style is easy to apply and take on & off
  • Prevents mildew, bedbugs, dust mites, and mold

This 6-gauge fitted vinyl mattress protector covers the top and four sides of the mattress or box spring, keeping it dry from spills, pet accidents, bedwetting and incontinence. The antimicrobial treatment helps prevent the growth of mold and mildew, extending the life of your mattress or box spring. The fitted design allows for easy installation and removal, just like a fitted bottom sheet. If an accident occurs, simply wipe down the cover with a damp cloth - no need for laundering! This vinyl cover is manufactured by Dry Defender.

Available in sizes from Twin to California King, this fitted mattress cover fits mattresses and box springs with depths of either 9 or 16 inches. To ensure the best fit, make sure to measure your mattress and box spring depth and order the right size cover. If between sizes, be sure to measure up as these covers do not stretch.

  • Full - 54 x 75"

Best I have found

I have bladder issues and embarrassingly I pee from time to time. My bed was such a wreck. I bought this and the first night I lost my bladder and woke up and removed the sheets and the protective cover and my mattress was dry. I put the cover back on and felt amazing. Besides sleeping a little warmer, I am totally happy will recommend over and over and over. 5 stars all the way. Thank you for making my life a little bit easier. God Bless.

very few liners actually keep 100% of water out, this one does

Quality isn’t as good as it used to be

Ordered this at the start of the pandemic. The quality at that time was very good, it was nice and thick. The one I just received is lacking in quality, the top is thinner and smells strong of plastic. I won’t be ordering again.

We are sorry to hear about the quality and smell of your cover. The manufacturer recommends taking the vinyl out of the bag and letting it air out for a few days to balance out any odor. Additionally, the manufacturer has confirmed that there have been no changes to this cover and the superior quality is the same year after year.

Best mattress cover

The Heavy duty mattress cover is perfect. Should last a long time with proper care. Unlike those cheap ones that get crinkly and tear. I got the 16” depth for my 10” full mattress and it fits perfectly. Will buy another for a twin bed.
