    • Purple foam is king!!!
Color: 2 Inch Purple-queen
OMG! I love this mattress pad!! And let me tell you, I've tried them all! From "pads" that were really just covers, to those fluffy ones that are basically comforters, some were better than others though. To two very expensive down and feather beds! One of which was really nice, but the feathers and down do settle down and lose fluffiness, so I was constantly having to take it off my bed and fluff it up.😫 I have a nice mattress so the two inch was all I needed. I just wanted a little more sinking in goodness!! This pad is perfect, my hips and shoulders sink in nicely so I'm not sore in the morning, but not too much so my spine stays aligned. Ahhhhh!! The size is a perfect queen and covers my entire mattress. I read a ton of reviews and a lot of them for the inexpensive blue and white pads complained they were hard. So I decided to pay a little more for the purple.💜 Good call! Lol! Been sleeping on this for a while now and it's amazing! No slipping around and it hasn't flattened at all, excellent bounce back. Like sleeping in a soft supportive cloud!! Honestly, having a hard time getting out of bed in morning!! Sooooo comfy!! Would definitely recommend! ... show more

    • So Comfortable – Best Mattress Topper!
Color: White-3 Inch-queen
I absolutely love this mattress topper! It made my bed feel so much more comfortable, and I sleep much better now. It’s soft, supportive, and stays in place perfectly. I wake up without the aches I used to have, and it really adds a luxurious feel to my mattress. It was easy to set up and expanded quickly. I would definitely buy it again and highly recommend it to anyone looking for extra comfort. ... show more

    • Keeper
Color: 4 Inch Purple-california King
4in is the best. Medium firmness in my opinion. Still breaking it in. My old one was squishy soft, this one is definitely firmer but I slept fine. Can't really rate the temperature since my ac is on 68° every night - everything makes me hot. No sweating. No odor. Don't be alarmed if the edges look smashed, you kinda just have to massage the flat spots to get some air and lay it flat for 24hrs. After I did that the edges all filled out. ... show more

    • Nice and worked for what I needed.
Color: 2 Inch Light Purple-twin
I didnt buy this for a bed I bought this to put on my daughters couch while dog sitting. Her couch was so hard I was having a hard time sitting on it. Pun intended. I tried blankets nothing worked so I ordered this. It came overnight and I was able to cut it to the couch size and put a sheet over it to keep it in place. It wasnt overly thick but for what I needed it for it worked well. ... show more

    • Comfortable and soft
Color: 2 Inch Light Purple-twin
Comfortable and soft. I haven't noticed a cooling effect but that may be subjective. Slight chemical odor upon opening that needed a full day in the air and sun.
