Excellent buy for dorm mattress! I looked for several alternatives and this was the best in price and quality. I read several reviews to be able to choose correctly and this was overall the best ranked in terms of comfort and price.

A true plush soft mattress topper! This is my second one of these. Just replaced my previous one that I had for four years. I attempted to try different types of toppers including goose down and goose down with the chunks of memory foam. Neither gave me the soft and cloud like texture I wanted. This topper is it!! And good value for your money. The previous one maintained its shape and softness for a long time. And I made sure to rotate it so one side didn’t become too deflated. For the price, you should definitely give this topper a try

I was worried since there’s so many mixed reviews, but I went ahead & got it & was pleasantly surprised at the quality of it. I have back pain (all over pain) from sports growing up & now working full time in healthcare. I added this ontop of my 3inch memory foam topper for a little extra Plushness & it has done well so far. I didn’t let it sit out the recommended amount of time but even for not doing so it still feels pretty nice. This is a California King size & they do come bigger than the actual mattress size but that’s alright :) hope this helps.

The media could not be loaded. So I waited approximately 68 hours and 40 minutes before I decided to put this in the dry on very low heat and for 20 minutes to fluff it. In my video I stated I was going to wait the full 72 hours. I realized from the start of the 3rd day I didn’t see a difference from 48+ hours. It’s been one night that I slept on it and wow! My boyfriend send it feels just like a cloud. I cannot feel my 10 inches mattress on this thing. I believe for the most part this mattress topper fluffed up to the full 3 inches but some parts still are flat. If I ran into any issues I might just request a replacement. I didn’t buy this to help my already old mattress, but I’m trying to make my bed a place for me that I never want to leave from. ALSO DISCLAIMER TO EVERYONE WANTING TO BUY THIS. THIS IS NOT WATERPROOF NOR CAN YOU WASH IT. I already bought a waterproof mattress pad that will go on top of here. If you have any waterproof concerns and just want this topper, I would skip out on this. Overall, I’m going to give this 5 starts and even if I ask for a replacement because I payed I good amount of money for this for all of it to blow up to 3 inches not just some parts. Also, the mountain range part of the mattress topper I stated when first opening it did level out. I do agree with another reviewer that some parts have more filling than others. I suggest waiting 48+ hours to let it fluff up and put it in the dryer on low for 15-20 minutes for that fluff. I personally live in a very warm place and this mattress topper did not make me hot. It makes thing a little warmer but not hot. Probably due to the cotton materials on top. Again I will continue to update. This was just night one with it. I’ll update if there are by lumps.

This is the second one of these I have bought in the last year. This topper is extremely comfortable and has a very soft pillowy/cloud like feel. The price point is perfect for someone on a bit of a budget. I normally get very hot when I sleep and I have no issues with this topper. It has just corner straps to secure it to the mattress which I prefer over the fitted sheet style sides as it doesn’t pull the edges of the topper down. Packing: it came vacuum packed in plastic, then wrapped, sealed and taped in another layer of packing inside the box. Keeping it safe from cuts & dust. There is no smell. I did allow it to expand a full night before putting it on my bed and shook it prior to putting it on the bed to fluff it a little. My first topper (exact brand) I put in the dryer on a low heat to tumble and it fluffed nicely then too. My only complaint is based around cleaning it. The first topper I bought ended up getting puked on by my sick child. It was not a spot/surface clean type situation. I had to take it to a laundromat to clean and their washing machine did not treat it well. The filling got very clumpy and there were several holes torn in the outer layer causing there to be filler fluff all over the place. The clumping of the filling was not evening out and felt uncomfortable to sleep on. I ended up getting rid of the topper after that and searching for a different brand that had waterproof/resistant and machine washable as noted features. The topper I went with was so uncomfortable, was just as lumpy as my ruined/washed clumpy topper that I went through the hassle of repacking it and sent it back. Ultimately I came back to this brand because of the comfort & price and decided it was worth the risk of it not being the most durable when it comes to cleaning.

Update!! I took away two stars and probably should take away more. I haven’t had the mattress topper for a month yet and I’ve spent most of the time since I had it in the hospital. I come home and sleep on it and notice it’s already coming apart at the seams like it wasnt sown together properly. I would return it if I could leave the damn house smh! I absolutely love this topper. It has a lot of cushion and is soft as a cloud. My finance said it makes our bed feel like we are at a luxury hotel. Ive recommended it to two other people already. Just get it!

This topper fits my sleeper chair perfectly and definitely makes it more comfortable to sleep on. It doesn’t roll up super compact, so keep that in mind if you’re short on storage space.
