Transformed my old mattress and improved my sleep!
Color: Swirled Blue
Size: Queen
Set name: 2 Inch
I am very happy with this mattress topper and consider it one of the best purchases I've made for my sleep. I bought it to add comfort to an old, stiff mattress that was becoming increasingly uncomfortable, and the difference was noticeable right away. I typically struggle with back pain, which often makes it difficult to fall asleep and stay comfortable throughout the night. Since adding this mattress topper, I've been sleeping much better. It provides the perfect amount of cushioning and support, helping to relieve pressure on my back and making my bed feel much more comfortable. The topper was easy to set up, fits well on my mattress, and has held its shape nicely. Instead of replacing my entire mattress, this topper gave it new life at a fraction of the cost. If you have an older mattress or deal with back discomfort while sleeping, I highly recommend giving this mattress topper a try. It has made a tremendous difference in my sleep quality and overall comfort.

The BEST Mattress Topper Ever.
Color: Blue
Size: Full
Set name: 3 Inch
I’ve had this mattress topper for 1.5 yrs and it is so durable. This is the most comfortable my bed has ever been! I wanted to save money on a mattress, so mine is just plain old springs. To make sure I got the best sleep possible, I started looking into memory foam mattress toppers and I am SO GLAD I picked this one. It’s almost too good to be true. Every time I wake up in the morning I don’t want to leave my bed! My body quite literally melts into this mattress topper, but not excessively where I’m uncomfortable. It’s the perfect balance for me. I don’t sink too much, but just enough to feel relaxed and at peace in my bed. If you have back problems, I would suggest you buy this. While not the remedy for any extreme back pain, I’ve noticed that with my mild back issues it is perfect for a good-night’s rest. In the past, old mattresses without a topper such as this one gave me really bad back pain in the morning. It supports my body perfectly. I personally have a mattress cover over the foam cover so I haven’t tried washing it, but I would say the full size one is way too large to fit in any type of washer. Speaking of size, this topper is definitely true to size so it fit my full size mattress perfectly. However, I’d keep in mind you may have to size up a bit in terms of sheets with this mattress topper on (I have a full size but with the topper I use queen size sheets).

We have loved these 4-inch mattress toppers. We bought two of them for the bunk beds in our van, and they have been perfect. They’re comfortable, supportive, and fit great in the space. We’ve been really happy with them and would definitely buy them again!

OMGAAAAAWD!!! HEAVEN!
Color: Blue
Size: Full
Set name: 3 Inch
All I can say is OMGAWD!!! Thank You~!~!! We got a new mattress after the previous "The Cloud" Serta pillow top (I'll never have another one) lasted for less than 8 years and I totally despised not being able to flip it models failed.. The new model is also a hybrid mattress, but is flippable and was just a bit too firm. I was feeling progressively more and more uncomfortable as the nights wore on, and with my serious back problems.. this just wouldn't do.. So I began searching "Our Beloved Amazon - heh" for an alternative, and after quite some time and research finally landed on this wonderful topper. It's like sleeping on top of well stuffed Ida Down on top of piles of silk. So very comfortable and my back pain is virtually completely gone now -such a relief! Be sure you follow the instructions on care and initial setup. You Do have to let it fluff out because of the vacuum packing (it wasn't really heavy btw). Mine decompacted fine, but I still want to run it through the dryer when we next venture to the laundromat. Shake it a little here and there when you take it out and at least let it sit for a few hours. It was just as easy to put on the bed as a regular mattress protector, and I also put my regular protector on top of it for added security and waterproofing. The materials feel like they are of good quality.. Viscose is also called Rayon and can be made from a number of different materials, so take good care of it and follow the washing instructions carefully. Delicate only, and cool only, and use only a horizontal washer that does not have a central agitator or you will tear it up. Only dry on low temperatures (preferably in a very larger laundromat dryer so it has plenty of room to loosely toss about. Drying it in the sun is alright as well, but it won't fluff like you want it to. I recommend using a waterproof and bug proof protector on top of this just to be sure you take care of it properly. Now I want to buy one for both my Mother and my Aunt HAHAHHA! TG it is in my price range.. barely. (Addendum: I have run it through the big dryer at the laundromat.. The dryer was cold so I gave it a quick warm on medium for anout 2 minutes and then tumbled on low for quite some time. The topper was fully ready in about 25 minutes, but I decided to elt it go on low while I did the rest of my laundry. It did perfectly and is just like the manufacturer photos.. I was so tired when I arrived home that I just flaked out on top of everything.. It was so comfortable that I was out liek a light in very short order and slept beautifully. I can attest that if you use this below your sheets instead of covering it with an additional mattress protector, that it does have better cooling effect. I will of course keep my waterproof/bugproof protector on top just for safety. The cat is nutz about the new topper as well.)

So comfortable, affordable and better than expected
Color: Blue
Size: Queen
Set name: 3 Inch
We were able to spend a couple nights with this topper when staying with friends, but trust these reviews, it is so worth it! Instructions said to let it expand for at least 48 hours, but this topper puffed up to the full 3 inches in only a couple hours when we laid it out on the bed. Fortunately there was no smell at all to off gas, which we were a bit concerned about. I noticed some reviews showed the topper getting a rip in it, one person said the manufacturer recommended using a topper cover, which we did buy at the same time. I already assumed we'd need to protect the topper from dirt, body odor and rips, and I reviewed the cover separately (also 5 stars!). After putting the cover on, we were able to sleep on it the same night. Boy what a difference! The support is so luxurious. You might think a foam of this type would sleep hot, but it really wasn't. I prefer a cool room with a comforter, and this topper prevents overheating with it's gel and the vent holes throughout. It reduced my tossing and turning through the night, and also dampened any bounce transfer when getting up, so not waking my partner. Within an hour of both of us getting up, the topper had returned to its full shape with no dents remaining. You may need to buy deeper sheets, but we had them already for the existing mattress. I did pull a footstool up to the head of the bed because the frame was already high, now it's really 'elevated' lol. at $51 it was much more affordable than I expected, even when adding the price of the cover.

Perfect level of squish
Color: Swirled Blue
Size: Full
Set name: 3 Inch
1) very comfy.. but comfort is all a matter of opinion and preference. For me it’s a perfect amount of squishy softness. 2) yeah you’re going to want to air it out when you first get it. It’s just how memory foam is. It has that fresh memory foam smell that’s unavoidable. So pop it open, let it expand, and give it some time to emit that chemical smell. It goes away. 3) yes you need to give it some time to fully expand to its most comfortable squishy potential. Even when I thought it was done growing I thought “oh no it’s too small!” But it grew some more. Just be a patient little panda bear and let it do its thing. Trust the process. 4) for the price, it’s a great deal and my bed is much comfier now. No need to spend a ton of money on some fancy name brand bedding..unless that’s your thing, chicken wing. 5) most importantly: my cat loves it. Stay comfy my friends!

IULULU Full Size Mattress Topper
Color: Swirled Blue
Size: Full
Set name: 3 Inch
The foam comes compressed and when gently spread out does not seem to fit the bed correctly, but given even a few hours to expand and things improve greatly. the first five photos are within 10 minutes of opening and unrolling. The last three are between 6 and 8 hours later. The pad is not 'fluffy', yet it gives way to the heavier body parts, meaning your hips and shoulders. The holes and gel help dissipate your body heat making it more comfortable. We have found I can roll to my other side without waking up enough to do what my wife calls a jerky roll, as in shift, roll onto my back, shift again, then onto the other side. I am able, now, to just roll, without pause, to the opposite side. Nice. The pad can be spot cleaned if needed, but a mattress topper works well for protection. Neither of us has noticed and noise coming from the topper (odd question). The topper pad does not flatten fully under our weight. It seems quite comfortable and much more comfortable than the mattress itself was.
