    Toxic Polyurethane smells so bad that it has been on my porch since I received it. It is absolutely unusable. Worst purchase ever!

    The mattress topper thickness was

    The mattress topper thickness was as advertised, but I don't think I realized this would just be foam with a cloth cover. The price for the product value does not match. The topper is not very supportive, there is a lot of sinking, and it retains a lot of heat.

    Soft but Moves Around Alot :(

    [This review was collected as part of a promotion.] For Reference: I’m around 50kg and I sleep alot on my sides but sometimes I sleep on my back. I also have Scoliosis on my back that would ache if I sleep on a mattress that’s too soft or too firm. The product came with the foam and the casing/cover separately. My first impression is that the material is soft and comfortable but I have to say that it’s quite challenging to put it together even when you have help from another person. I can only imagine how it must’ve been harder if you decide to set it up alone. It’s not something impossible to do by yourself but it definitely needs some patience to put the unroll the foam and put it inside the cover/casing. But, the fact that the cover is separate from the foam means that it would be easier to clean since you can just throw it inside the washing machine and not worry about how to clean it if it gets dirty. The next thing I notice when setting it up is that the topper doesn’t have any straps to help secure it to the mattress so it doesn’t move around. Which is a BIG CON about this product for me. Because the amount of time I had to adjust the topper is just too much, as I had to adjust it every day. When I lay down on the topper after setting it up, my first impression is that it’s very soft and have a cloud like feeling as it seems like you’re floating on top of the mattress. I sleep alot on my sides but sometimes I also sleep on my back. I have no problem when I sleep on my sides but when I do sleep on my back, I would wakeup from my back aching because I have no support. And it’s also not a good combination if you like to sit on your mattress during the day. IN COMPARISON : I use the soft topper from Helix and I love that better compared to this. The Helix has more structure to it, it’s a combination of both soft but yet not too soft. And It has STRAPS to secure it in place, never thought that this would be a HUGE plus when choosing a topper but now I learned something. I never needed to adjust it constantly. CONCLUSION: If you’re looking for a soft topper and sleep on your sides then this might work for you. But, if you like to sleep on your back, I wouldn’t recommend this product since it doesn’t really give any back support. keep in mind that it’ll move around alot since it doesn’t have any straps that goes under the mattress to secure it in place. It has a washable cover that you can take off if it needs cleaning, so that’s a plus. But, Overall it’s not something for me.

    Soft , cozy comfort that makes a difference

    [This review was collected as part of a promotion.] This mattress topper completely changed the feel of my bed in the best way . It adds the perfect balance of softness and support without feeling too heavy. Installation was super easy, and it extended nicely after unpacking . I also love how clean and luxurious it looks on the bed . Sleeping feels much more comfortable now , especially for my back and shoulders . It’s lightweight , comfortable , and makes the whole bed feel more premium and cozy . Definitely not just an ordinary topper.

    While it has provided the extra softness I was hoping for, the fit inside the cover is off. It also moves on the bed making it off center.

    Mattress too firm? Try Casper topper

    [This review was collected as part of a promotion.] The casper mattress topper is a bit too soft for me. Got the feeling like floating almost like water bed. I think it will be perfect for those looking for soft bed as I prefer a bit firmer. I love that it come with a cover.

    I bought the Casper Dream

    I bought the Casper Dream and it was too firm for me. I’m a side sleeper and I woke up every night uncomfortable. I almost sent it back until I saw the good reviews for this. Bought it online at 3 am when I’d woken up yet again and it was the last straw. This topper saved the mattress from a return.

    I got the 3 in

    I got the 3 in mattress topper for a ten year old queen bed that was slumping in the middle, it has caused back pain but now my bed situation is so much better it’s so cozy and makes it feel like a new mattress. I have a king bed Casper hybrid mattress too for a few years and I feel it’s just as good :) get one!

    Awful.

    Topper is constructed of cheap egg crate foam inside. Very squishy and unpleasantly soft. Sheets don’t stay tight on topper. The only thing I like about topper is the zippered outer shell.

    So far so good. Love

    So far so good. Love the 3" foam. Makes the Casper foam mattress, which we really like and have, much more comfortable and I am sleeping much better. I am a side sleeper and have dealt with sore shoulders from sleeping on my side. The level of discomfort was greatly reduced by using the mattress topper. . . seems to be a good investment.
