Quality

Can be sturdy, but also prone to defects.

Can be roomy, but may not fit snugly on all mattresses.

Best pad and absorbs any liquid.  I had bought this before years ago. Lucky I remember the name of the product. I highly recommend this product. +++++

Never knows when 1 needs a cover for loss urine

Looks good

My last one was,on my bed for 18 months zero problem.

Has one before

The quilted pad part looked and felt nice but I returned it because it was lined with plastic. I thought the plastic could make the cover slide around, be noisy and make one feel sweaty.

Be aware this mattress cover has a plastic lining

Top quilted part is of good quality.  Only drawback is the heavy vinyl under layer.  Takes ages to dry it.

Good product

The mattress cover is waterproof which is good for preventing stains. However, it is made of plastic on the inside which makes noisy ruffling sounds when you move. It is hard to sleep because of how noisy it is

Inside made of Noisy Material

A little bit too loose and is not tight fit for a 6" mattress.

Loose fit

Horrible- we used it for about one month. It made our bed feel hot and plastic, and was very loud when lying on it or moving around in bed. Made loud crinkling noises with every movement. Then when I washed it, the whole thing tore completely during the first wash.

Noisy, hot, and rips instantly

Terrible product — total waste of money!
I've used a Mainstays mattress pad for over 6 years without a single issue, but this one is downright awful. The so-called “waterproof” plastic lining makes it noisy and slippery — it slides around with every small movement, bunching up the bedsheet and never staying in place. It doesn't even fit the mattress properly. Absolutely horrible quality — do not buy this product under any circumstances!

Plastic,  Noisy- total waste of money!

Unfortunately I do not want plastic on my mattress pad and will be returning this. I tried to see if it had plastic before I bought it, but couldn't (until I opened it).
