Mellanni Extra Deep Pocket Full Size Fitted Sheet - Cooling Bed Sheets for 21" Deep Mattress - Luxury 1800 Thread Count - Wrinkle, Fade & Stain Resistant - Breathable & Soft - 1 Full Size Fitted Sheet Only (Full, Blue Hydrangea) - Perfect for Guest Rooms, Dorms & Hot Sleepers

Item fit the bed perfectly. It is not a zipper version so it will not protect the bottom part of the bed. Apart from the top of the fabric (feel like over heated microfiber towel) underneath it is pure plastic.This is the first time I’ve bought king size sheets that are actually deep enough not to come up off the bed after sleeping on them for several nights. Other “deep pocket” sheets haven’t cut it - but these actually fit!We love this sheet! it is soft and comfy and it stays on our bed. the corners stay where they belongI’ve order this before, needed another fitted sheet, and I knew what a great fit and soft feel this sheet had, my mattress is 10 inches thick, so I need the deep corner pockets. This fitted sheet fits perfect, hugs the mattress.this is the second fitted sheet that I've ordered from this company and I'm extremely happy with both purchases! Softnness and fit are exactly what I wantedThis sheet is very soft. It fits the deep mattris. The price is a lot better than in a department store.Super softI bought this fitted sheet to use on an 18" high air mattress for when I'm tent camping. It fits perfectly with plenty of sheet going on the underside of the air mattress. Now I'm using it in my spare room with a 3" memory foam gel topper and it still fits. The fabric doesn't go under the bottom of the mattress as much as it did without the topper, but enough to keep it from pulling up. I especially like that the elastic goes all the way around the sheet for a nice snug fit. I'm ordering another to have an extra sheet on hand.I have resisted buying microfibre sheets since they were first introduced, but natural fibres are so expensive these days that I had to compromise. I searched online for "best microfibre sheets," and the Mellanni brand came up as recommended. We received the sheets promptly; they washed up nicely; and they fit our bed well -- a little loosely actually, but not uncomfortably so, and a whole heck of a lot easier to get on and off than the high thread-count cotton sheets that had reached the end of their life. They are also super soft and silky. Spouse called them "very sexy."The 4-star review reflects the fact that I don't yet know how well the sheets will wear in the longer term. Also, if you purchase a deep colour, as we did, make sure to was them separately the first few times. Our formerly white pillow protectors are now a shade of blush pink after being washed with the sheets (2nd wash for the sheets). No serious harm to us, but do be careful what you throw into the same load when these sheets are new.i just ordered two more fitted sheets because i am so happy with the ones i got. i sleep very hot and usually the bed and my night gown are soaked by morning. i didn't really expect these to help but they did. they are very soft to the touch and comfortable, easy to get on my cranky murphy bed and somehow they work....the bed is not soaked in the morning and this IS our hottest time of year.This is a micro-fiber sheet, which is not what I wanted. The description mentions it is micro-fiber several bullets in, so not an attempt to mislead. The star rating in no way reflects the quality of the product, but Amazon requires a selection. It might be a perfectly fine sheet, just not for me.I don't like to review until I have used the item for a while. I used these for my campervan over my memory foam mattress and it's nice and silky to sleep on. PLUS I just did my first standard wash (I didn't even use the "delicate" wash setting on my washing machine) and its still very silky. Very pleased so far.The pearl grey colour is exactly what I was hoping for It's also pretty resistant to my cat's claws which is good. Fits well. I'm happy.
