Review: Extremely High Quality Product - This purchase was worth getting. This was more expensive than some of the other options in this category so I hesitated on purchasing this one at first. After getting it, a few things stand out: it's very high quality. The fabric feels nice, it looks nice. One great feature is the zipper is easy to locate and it's orange and well built, so it's really easy to put it on the mattress. The stitching, the material, all of it seemed to have a lot of attention to detail. So far, it seems great. It seems extremely well made. Although I didn't purchase any comparable products, I feel like I made the right decision and it feels like a lot of detail and care was put into this product and it's worth the small premium over possibly cheaper alternatives.
Review: Snug fit and material is strong - These mattress protectors fit my 9” twin mattresses snuggly, which is what I was looking for. The zipper is durable and material is more cloth like than others, so it doesn’t sound like plastic. Will buy again if that time comes!
