    • Very good pad
Size: California King Style: Microfiber
I was worried that since this this mattress pad was waterproof/resistant it would be crinkly or too hot, but it has not been a problem. It fits well and doesn't slide. It is durable, washes easily, and has kept the mattress clean. We've had no problems.

    • Fit My California King Perfectly!
Size: California King Style: Bamboo Charcoal Fiber
A good fit is a must in order for a mattress pad like this to provide the protection you need and the comfort you want! This gets five stars in both areas! I have one of those memory foam mattress toppers on top of my mattress and box springs. The mattress was way too firm for my liking so the memory foam provided the "sink" that I needed. The problem was that the "sink" was too much. This mattress pad didn't kill the memory foam, but it did firm it up enough that it provided the perfect comfort I was looking for. Not only did I sleep better, but I didn't feel near as hot. Very glad I made this purchase! ... show more

    • Very good bed protector
Size: Queen Style: Microfiber
Bought this product a year ago when my son was transitioning fully out of pull ups. Easy to put on the bed. Dried quickly on the clothesline. It was soft and protected the mattress! However a year later & any accidents means the mattress is wet depending on how much liquid.

    • Game changer, money saver, 100% worth it
Size: Full Style: Microfiber
This has saved our mattress and money. After our son's 3rd accident in bed (it didn't happen often but 3rd times a charm), we heard about waterproof bedsheets and I purchased this game changer. It fits perfectly, the sides are of good quality material that doesn't rip and the sheet soaks up the accident without it leaking onto the mattress. We just strip the bed, throw it in the wash and put it back on. We weren't stressed or putting stress on our son about having accidents anymore and everything improved. Best part is, we don't have to replace our mattress. Saved us tons of money. We bought for the other beds as well ... show more

    • Great gift
Size: Queen Style: Microfiber
My daughter is five months pregnant with my first grand baby (granddaughter) and was sleeping on a mattress she said had springs poking out! We cannot have that…can we? So, despite the fact that I just purchased a hybrid bed in a box at Walmart for my other daughter who went away to college, I researched what the best affordable mattress is right now and I read ALL the reviews I could find on Amazon. After much research, I went with this mattress and later realized that the wal mart bed in a box was almost exactly the same. Both my daughters love it! My pregnant daughter said she only woke up one time in the night and that had nothing to do with discomfort like it had. She just needed to use the bathroom which is very normal for halfway through one’s pregnancy. Since we are separated by distance, this was the one way I could be there for her. GREAT PURCHASE! for under $500, I got the mattress and 2 year warranty, the waterproof mattress cover, sheets and comforter, and the Bed frame. Deal of a lifetime and it’s not even the big sale yet! She’s pleased so I’m pleased. Only minor issue was that they could not use the base due to the holes not matching up and couldn’t be screwed together. Minor screw up lol. But true to Amazon the return policy is made easy and I will be purchasing a little better one when the refund comes. Hopefully during the BIG SALE that’s in a day or two. I Hope My review helps someone in the decision process. Good luck mattress shopping! She did not share a photo yet but if she does I will try to add that to my review. ... show more
