Customer Reviews & Questions
Review Summary
Summarized by generative AI from text of customer reviews
Customers overwhelmingly praise this mattress protector for its soft, breathable fabric that feels like premium bedsheet rather than plastic, with a snug fit that stays secure even on deep mattresses up to 16 inches. Reviewers highlight the high-quality cotton material, effective allergen and spill protection, and durability through multiple machine washes. Most find it comfortable and luxurious. A small number report installation challenges on larger mattresses or occasional stitching concerns, but these remain isolated cases. Overall, customers strongly recommend it for quality and performance.

The Company Store mattress protector arrived in compact packaging and protected the cover during shipping. I am very impressed at how easy it was to apply to my mattress. With two people, it took less than 5 minutes. My wife and I have been sleeping with the mattress protector enclosed outside of our mattress and it has kept our mattress clean and helped reduce exposure to dust mites. The zipper closure keeps the mattress free from any damage from sleep sweat and spills while in bed.

My 12 year old is spills everything! I decided to buy her a new bed, and I put this protector over the mattress and I just went to go take everything off to wash, the outside was pretty gross but not a drop was on the actual mattress! These protectors are very nice, they look like a sheet, they don’t have that plastic sound, they look and feel like a sheet! If you are in the market for a new mattress or box spring protector, I cannot recommend this enough!

The Company Cotton™ Mattress/Box Spring Protector. The average pore (open space between interlocking yarns) size is <15 microns. The average bed bug is visible to the naked eye at 1/4"" to 3/16"". A quarter inch= 6350 microns. In contrast, dust mites are microscopic at an average of 250 microns. Thank you for your inquiry.

My mattress is flippable. Can this cover flip with the mattress without removing it?

Hi Carlee. The Mattress/Box Spring Protector encases the entire mattress. You should be able to turn your mattress over without removing the protector if done carefully. Thank you for your inquiry.

Is this mattress cover suitable for adjustable beds? Our current mattress cover and sitter sheet comes off every night while we sleep. It's a huge mess. Since this zips, does it have enough give to account for the different positions?

Hi Jes ~ Unfortunately the Company Cotton Mattress/Box Spring Protector would not work on an adjustable bed as the fabric is tightly woven to protect against pet dander, and other allergens. We are sorry to disappoint you. Thank you for your inquiry.

Does this cover provide protection from dust mites? Can it be washed with hot water to kill any allergens that accumulate?
