Soft and comfy
Color: Green, Size: Twin, Color: Green, Size: Twin
This mattress pad is much thicker and fluffier than the one I had before. With I took it out of the package, it was vacuum sealed with a note saying to leave it out in the sun for 48-72 hours or fluff it up with a hair dryer. I put it in the dryer on medium heat, which worked nicely. The pockets are really deep on this mattress pad and it fits snug. You don’t really see the shape with a sheet on top. It feels comfortable laying on top of it. It doesn’t flatten much when I’m laying down, but I imagine over time it will lose fluffiness. Overall it’s comfortable and breathable.

Good for already soft mattresses, 1in thickness.
Color: Dark Grey, Size: Queen
If your mattress is already soft, it will help. It's less than 1in thick after tumbling for 40 minutes. It did fit my queen bed and felt somewhat soft when laying down but it didn't help much as far as comfort. Quality wise it looks good, not cheap and while my sleep quality wasn't improved, it might help someone with a better mattress than mine.

Must have for mattress comfort and protection
Color: Green, Size: Twin, Color: Green, Size: Twin
I ordered the BDEUS Twin mattress topper for a temporary mattress. The topper definitely improves comfort and regulates temperature much better than just the mattress and sheets. The cover fits deep mattress easily fitting over my 13” mattress and could easily fit a much deeper bed. The padding is thick enough to provide some additional support. This model also has a thin sheet of waterproof material to help protect your mattress against spills or liquid damage. This layer is cover by the pillow top and does not seem to make much if any noticeable noise. Overall this is a high quality cover and mattress protector in one. At <$45 at the time of this review it provides an incredible value.

Topper
Color: Green, Size: Twin
I recently purchased the BDEUS Twin Mattress Topper Viscose Derived from Bamboo, and I am thoroughly impressed with my experience.
The comfort level is absolutely a 5 out of 5. The viscose bamboo material feels soft and plush, making my bed significantly more comfortable to sleep on. I wake up feeling well-rested and supported, which has been a noticeable improvement from before.
Here are some of the main pros and cons:
Pros: Incredible comfort and softness, high-quality materials, fits the twin mattress perfectly, and helps with temperature regulation throughout the night.
Cons: Name
Overall, I give the BDEUS Twin Mattress Topper a solid 5 out of 5 stars. It has completely transformed my sleeping experience, and I would highly recommend it to anyone looking to enhance the comfort of their bed.

Adds comfort and support
Color: Green, Size: Twin
I’ve been using this bamboo mattress topper for a couple of weeks now, and it completely changed the feel of my bed. My mattress was starting to feel too firm and uncomfortable, especially on my lower back and shoulders, but this topper added the perfect amount of cushioning without making the bed feel overly soft or saggy.
The cooling effect was one of the biggest surprises. I tend to sleep hot and usually wake up sweating during the night, but the bamboo-derived fabric feels breathable and much cooler than regular mattress pads I’ve owned before. It stays comfortable throughout the night and doesn’t trap heat like memory foam toppers sometimes do.
I also really appreciate the waterproof protection. It gives peace of mind without feeling stiff or making that annoying crinkling noise some waterproof covers have. The surface still feels soft, plush, and smooth. It honestly feels more like a hotel-style pillow top than a basic mattress pad.
The thickness is just right for pressure relief. It helped reduce the soreness I usually wake up with in my back, and I’ve been sleeping much more comfortably overall. The deep pockets also held securely on my twin mattress and didn’t slide around, even after moving a lot during sleep.
Another thing I liked was how fluffy and well-made it looked right out of the package. After letting it expand for a bit, it became nicely plush and evenly padded. The stitching seems durable, and it still looks great after washing.
If you’re looking for a softer, cooler sleeping surface with added waterproof protection and better support for aches and pains, this mattress topper is definitely worth it. It made my bed feel newer and far more comfortable without needing to buy a whole new mattress.
