This topper comes packaged nicely in a small box. It takes a few hours for it to expand once you take it out of the vacuum sealed bag and there's a light odor as is the case with memory foam items. The odor goes away relatively quickly. The topper is very plush and comfortable. the elastic straps keep it in place on my mattress. I got the queen size and it it the same dimensions as my mattress. It's a good thickness too but my sheets still fit perfectly. i like the quilted design and it feels like they used quality memory foam. It's made my 8 year old mattress feel new again.

Nice, soft and a little puffy! This mattress topper is incredibly soft and feels like sleeping on a cloud. The 100% cotton material is breathable and keeps me cool throughout the night, which is perfect if you tend to sleep hot. It also provides great support and has helped reduce my back discomfort. Definitely a great upgrade for a more comfortable sleep!

The overall filling is solid and uniform, and it won't deform or collapse even after being pressed for a long time. It has a long-lasting and durable rebound force. Even when used daily for a long time, it remains fluffy and comfortable. The support is moderate and does not collapse. It can disperse body pressure and is comfortable when lying flat or on your side. It allows you to sleep soundly all night without feeling tired. Placing it in your bedroom instantly enhances the comfort of your sleep, and it is highly practical.

Our mattress was old and needed a replacemente because it was causing pain on me and my husband. While waiting the new mattress my husband decided to sleep in the guest room and realized the mattress was on the tough side. I decided to give this topper a try and it was the best decision. It arrives very compacted, right out of the package it is pretty flat, but within a few hours I could tell it would be comfortable. I had to fight my husband to keep him off for at least another day to make sure he would get the real experience. The next day I layed down to try and next thing I know I took a nap in the middle of the day! It is very comfy, and the temperature was just right, even for woman going through menopause. His pain went away and he slept great again. So much so that I was was concerned our new mattress would be a disappointment! It added some thickness to the mattress, and the fitted sheet was a bit snug but worked. Totally worth it.

Took about 6hrs to fluff out fully. Tonight my first night sleeping on it and thought I haven't slept yet I can say it is nice material, soft, and comfortable. As far as thickness I thought from the pics and listing that it would be a tad bit thicker, but I believe the way it was vacuumed packaged has a big part to why it didn't fluff out to its max capacity.

After a couple days of letting cover fluff, I feel like I’m having a spa experience, no cap!! I love laying on the amazing fluffy pillow top. This is the real deal!! Comfy and feels like great after a long day. It’s so funny how it was so flat and the amount of fluff and comfort it had in a couple days!! Great quality and perfect price! 💜💜💜💜💜
