Customer Reviews & Questions
Review Summary
Summarized by generative AI from text of customer reviews
The mattress protector is generally considered a high-quality and effective product. Most reviewers found it well-made, durable, and successful at protecting the mattress from spills and wear. Many praised its soft, quiet, and comfortable feel. However, some had issues with the zipper being difficult to use or breaking, and a few found the material too noisy or plastic-like. There were also concerns about the sizing and fit not being optimal for all mattresses. Overall, the consensus is that this is a good quality protector that effectively shields the mattress while maintaining a comfortable sleeping surface.

I bought this a couple weeks ago. It seems difficult to keep it in place on the mattress. Not sure I’m going to keep it

Hi. Thank you for taking the time to share your honest feedback with us. We’re sorry to hear that you’re having difficulty keeping the Company Cotton Waterproof Mattress/Box Spring Protector in place. The protector is designed to fit snugly around the mattress, so if it is not fitting securely, it may be a size issue. We recommend reviewing the product measurements—including the depth of your mattress—to ensure a proper fit. Additionally, we suggest laundering the protector prior to use according to our care instructions: machine wash cold on a gentle cycle with like colors, use non-chlorine bleach as needed, tumble dry low, and do not iron. Please note that our products are cut slightly larger to allow for shrinkage during the first few washes, which can also affect the initial fit. We will provide the link to our return instructions, should you wish to return your purchase. If you need any assistance, please do not hesitate to contact us at 1-800-323-8000, or you may email us at custserv@thecompanystore.com. Your satisfaction is important to us. https://www.thecompanystore.com/returns

I am disappointed with this item. The pros are that the fabric is very smooth, solid, and bright white and the seams are sewn well. However it is also quite loud and synthetic feeling, despite being made of 100% cotton. The packaging indicated that it is coated with polyurethane. The zipper is cheap and I had to be very careful while zipping in order not to break it or rip it from the fabric. I do not consider this item to be worth the price premium over cheaper alternatives.

Love the security it gives my new mattress
Love that it protects against dust mites and bedbugs and it fit very well around my 10 inch mattress so the sizing is very good and it's easy to put on. Only thing is the zipper is near invisible so I could barely find it lol

What is the pore size in microns, please? Does the zipper have a cover at the end of it? Thank you.
Noel
03/29/2024
Hi Noel. The Waterproof Mattress/Box Spring Protector. The average pore (open space between interlocking yarns) size is <15 microns. The average bed bug is visable 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. The cover has a zipper at the end that wraps around the corner. Thank you for your inquiry.

On your mattress/box spring encasement, they are separate encasements is that correct? One encasement for the mattress and one encasement for the box springs?

Hi Cindy. The Company Cotton Waterproof Mattress/Box Spring Protector is designed to cover a mattress or a box spring. This product is offered in a 9"", 12"" and 16"" size to accommodate the depth of your mattress and/or box spring. Typically a mattress and box spring used on together on the same bed are the same depth as each other, however if they are not, you should choose your size accordingly. Thank you for your inquiry.

What size for a 10"" mattress?
Anonymous

Hi Nelson ~ We recommend going with the 12 inch size. We also recommend to wash the Company Cotton Waterproof Mattress/Box Spring Protector prior to use. This will tighten the weave for a tighter fit. Thank you for your inquiry.
