Very Soft. Fits the Bed great if you have a deep mattress. Great Price.

This fits a standard queen size mattress very well. I haven't washed it yet though.  It is very quiet, doesn't 'rustle' like some vinyl protectors do.  Also, it seems to be much cooler than some other protectors I've used in the past.

I bought this for my futon mattress, which is about 34 x 74 and it fit perfectly. It would be a bit short for a regular twin bed mattress, however. There is a rather strong chemical smell but I didn't air it out beforehand and after a while I got used to the smell. My futon mattress is not the most comfortable so I am happy for anything that adds some depth and cushioning.

Didn't have any good depth choices for my 10" matress, so ended up with this 16" cover.  As expected, it's loose, and like all Vinyl covers, you'll want a good mattress pad to mask the sensation of sleeping on plastic.  However, it serves it's purpose and I'm confident the mattress will never have a mold or bed-bug infestation.

Just what I wanted - Put a Tuft & Needle King mattress on top of this and it fit perfectly. Winning.

Works great.  Fits very well.  Has a nice feel and easy to wash.  It is soft and doesn't have that "plasticy" feel that most mattress covers have.

I washed the cover as to directions and cover came out perfect.  I have a 8"H Cal-King mattress  with 4" added foam on top and the cover still has plenty of room for  coverage.  Cover fits snuggly. Really like this item.  If ever I needed another, I certainly would buy it again.

Fits over my 10" deep mattress beautifully, even with a 4" memory foam topper. The fabric, color and finish are lovely, and the sheet is both well-made and durable. A great buy.

// FIT
This fits a queen sized mattress that is about 10 inches deep really well. I feel it could work on a deeper mattress as well. Slept on it for a couple months now and noticed that it stays in place toono having to adjust it like other mattress covers.

// FEEL
Plush! We have an overly-firm mattress and I was deeply surprised that this made it feel really comfortable overnight. Our mattress was so firm my arm would go numb when on my side. With this on, that no longer happens.

// CONSTRUCTION
I feel this is well constructed, and the materials felt good. The top of it is so smooth and soft. I haven't noticed any piling up or soft spots forming from use (will update review if I do in the future.)

I HIGHLY recommend this for anyone that has an over-firm mattress. Could work well to help make even a futon mattress fell better.

It fit really well on our king mattress. It doesn't make that crunchy sound others make. I've only spilled a little water on it so I'm not sure how strong it would be if I spilled red wine.

Perfect fit for a 12 inch mattress. The quality seems good; feels soft and not shiny/paper-like as I thought itd be

I have had a problem finding a set that fits my high (large) king size mattress.  This one finally worked.  It looks great and so far I love it.  Haven't tried to wash it yet.

I purchased this item for a second home in NYC. It is a god quality and it fits our deep mattress perfectly. It also adds a nice layer over the mattress. I would order this product again.

I have a king size bed and it can be difficult trying to find a comforter that fits into my duvet. This fit perfectly though, and makes my duvet so fluffy and comfortable!
