Worked for what we needed it for, which was moving. Very thick material, slid on like a pillow case and had extra at the end for folding over and taping down. Definitely can get more than one use out of this. We folded this up to use again in the future. Would buy again!I bought mattress covers at our storage company’s store. They did not fit any mattress. This mattress cover I ordered from Amazon was great with a little extra material to spare and was thick enough that I am not worried about it being in a storage unit. Great product.I originally purchased these for a move we made to a new house. They worked great but I had extras and used them again when it was time to bag our old mattress for a new one. I have done this now three times in the last few years, the bags work great. Plenty of room to get it in inside and very, very tough. You can grab the bag to lift the mattress if you have to. Yes, they are pricy, but you get what you pay for, and these worked perfectly.These bags are great for mattresses, box springs or even bigger furniture. We have used them for both and have yet to be disappointed! You can fit so much into these and once they are sealed good, keep unwanted dust or bugs out of it. Keeps furniture nice and clean and also avoids dampnessGreat for storing a mattress. Thick, heavy duty plastic. It would be nice if there was a zipper or velcro to close the bag.The covers were worked perfectly for their intended use!It worked perfect for what I needed it for.big fits great only down fall you need to tape it shutGood quality, heavy duty plastic use them for mattresses we use a few times a year and are stored in a basement. the tape is coming off without ripping the plastic after two uses.Did a perfect job for our king Endy mattress!Le bout ou entre le matelas ne ferme pas pas de vélocros ou autre dispositif pour qu’il soit fermée étanche.
