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.

BDEUS Twin Mattress Topper, So Soft
Color: Green, Size: Twin, Color: Green, Size: Twin
Having purchased BDEUS products in the past, I was very looking forward to ordering the mattress topper made of viscose (a material derived from bamboo) just to see (and feel) the benefits of the material.
My concern about the material, viscose derived from bamboo, is that the process to manufacture the material can be chemically intensive leading to harsh smells. I can say the topper has no off-putting smells. The quality of the manufacturing is present as there are no loose threads/seams, the material has no defects, and the print is uniform. The use of the material also leads to increased durability while enhancing the topper’s breathability and cooling properties.
The topper is fitted meaning the topper will not come off the mattress very easily (even though you may need sheet straps if you are a wild sleeper). But the softness is wild, I mean this has to be one of the softest materials I have felt, and it feels very luxurious. Waterproofing and moisture-wicking is also a benefit as small spills are not absorbed into the fabric.
The topper is also very thick and plush, and while the product listing touts “Back Pain Relief” it may be too soft depending on how firm, or soft, you prefer your mattress. I have to say this is definitely a five-star offering from BDEUS. This topper is for my daughter but I’m going to order a queen-sized topper for my bed as the price is just right.
