Son tal como lo describen, no son muy calurosas, son impermeables, lo único es que le quedó un poco grande a mi colchón.

This cover is awesome - slips on easy, cleans up well - and it works. We stood the mattress up on end and slipped it over, laid it down and pulled it over and zipped it up. My little old lady cat had an accident on the bed and the cover did its job, thank goodness. We had JUST gotten a new mattress! 😮💨 Highly recommend.

So far it's mostly good - only just put it on the bed so not yet sure if it helps my allergies but if it even remotely does what it says as far as blocking dust mites I imagine it will. It fits my mattress well & was as easy to put on as a thing that fits all the way over your mattress could be, lol. The only thing is it seems like my bed is super loud now, sadly. Like, it just seems to make a ton of noise anytime I move my pillows around and they happen to brush against each other as I'm arranging them when making the bed, etc, and even when I get in the bed and move my feet around or anything it just makes kind of a loud noise compared to before I had this on. Sounds pretty similar to if you were to run your hand quickly over the side of a tent, weirdly, or synthetic fabric coat sleeves rubbing against the body of the coat. Hopefully I'll get used to it and think nothing of it soon. I think I'd rather a slightly noisy bed vs. Allergies, and at least it isn't like a crinkly plastic type of sound, not super loud when slowly adjusting but strange noise if you run anything over it quickly (even with 100% cotton sheets over top of it)
