Wow
I am very happy with this addition to my bed. I already have a 10” memory foam mattress, but the thought about adding more foam, was very appealing. So this topper adds another 2” to my bed. That's a high fall to the ground. Lol! Unfortunately I did not wait the suggested 24 hours for the topper to take its form, however great news folks! It went into its perfect form in about an hour. Putting it under the mattress cover was a breeze. Laying down was such a joy. The softness I felt under my body was divine. It's extremely comfortable. Since I'm writing this review on a winter day, I can't comment on the cooling, however I can say that I was neither hot or cold. In all, I'm happy with the addition and definitely recommend the product to anyone looking to make their bed soft and comfortable.
I'm very impressed!
I am loving this Serta mattress topper! First things first, the packaging was well done. I don't have a covered porch and it was exposed to a rain/snow storm, without issue. It was compressed, so I opened it in a large space that way it could expand, which didn't take long at all. I let it set overnight, though, it was at its proposed size after just 30 minutes. My 2 inch topper was just over 2 inches and fit on top of my queen mattress perfectly. I have a 12 inch pillow top that is about 10 years old. (I need a new mattress, but that is not in the cards for me at this time, so I was eager to try this.) My typical queen sized flat sheet doesn't lift at the corners with this on top, but it does show some of the white mattress. I tested with a deep pocket fitted sheet and there isn't any mattress showing. My first night sleeping on this was heavenly! It was firmer than I thought I'd like, but to my surprise I love it! It's firm, yet plush at the same time. I have been sleeping on this for a week now. I fall asleep just moments after laying down, I'm not waking up sweating like I typically do, and my pinched nerve and hip pain have not been triggered. Plus, my kids have fun pushing their hands down on it, to watch it mold to their hand shape and bounce back. It really does confrom to your body as you rest. I didn't think a mattress topper would make such a difference. Especially at just a 2 inch thickness, but it really has.
Comfy!!
I needed a little extra cushioning for my back. I got this and put it on the bed. It seemed really thick and plush. That night I slept like a baby and didn't toss and turn like I usually do. I woke up with way less back pain and side soreness. I know this will hold up for a long time because I trust the Serta brand and know that Serta is high quality. This cost way less then going out and buying a new mattress. I also was nice and cool all night. Sometimes my husband tends to sweat and this really helped him and he was way more comfortable at night. No throwing off the blanket all night from being hot and cold. I will definitely be buying another one off these the the guest bedroom. I will definitely recommend this Serta cooling memory foam mattress topper to others. I love it and I love Serta!
