I bought this for my 6 in. thick box spring. Easy to put on and fit like a glove.
Very pleased with it.
As someone trying to control a raging dust mite allergy, I embarked on a wholesale purge of my old mattress, pillows, and linens. I wanted organic cotton mattress and pillow protector, and was so pleased to find Bargoose. The covers are very soft and unobtrusive under my sheets and pillow cases. I have an 11" mattress, so bought the 12" cover, and it fits well with just a little extra; hoping this is enough shrinkage allowance when I wash the cover eventually. Kudos also for the affordability! My daughter was also on a hunt for mattress protectors, and ordered a set based on my recommendation. You should, too!
Fabric is highest protection for allergies yet extremely breathable. Easy to wash and drys quickly. Extreme comfort to sleep on.
Easy to put on and nice fit. I feel confident they will protect our camper mattreses through the off season.
