The new CS 300 s4 Cento subwoofer is the perfect enhancement to every sound system, to fully enjoy the authentic Hertz Sound Experience!
The R & D team, always at the forefront in the search for innovative solutions, with unfailing effort, succeeded in obtaining very powerful bass frequencies from ultra-compact sealed enclosures, optimizing all the electroacoustic parameters according to the target set: high performance with boxes starting from 32 l. for the 30 cm (12 in.) CS 300 model.
The 4 Ω single voice coil configuration offers maximum compatibility with any type of amplification and an enclosure that houses more than one subwoofer.
The reduced depth, the compact magnetic group and the lack of rear decompression hole allow the box to be shaped around the subwoofer obtaining a depth close to the one of a speaker for maximum freedom of installation on any type of car.
The special cooling system of the six-layer voice coil keeps the operating temperature within an optimal range even in case of extended listening sessions at high acoustic pressure.
An innovative system of dynamic fluid optimization and turbulence reduction, obtained thanks to the spider support acting as an air conduct towards the venting holes on the basket, drastically reduces the acoustic distortions generated by the air compression at high excursions.
The cone geometry, the suspension and the spider have been designed using FEM (Finite Element Method) simulations to obtain the best performance configuration that guarantees control and low distortions even at high mechanical excursions of the mobile group.
The terminal block uses solid push connectors that accept cables up to 8 AWG to offer low wiring resistance and maximum ease of connection even in installations with multiple subwoofers.
The subwoofer is also provided with an elegant high resistance ABS plastic gasket that allows the grille to be fixed to finish the installation.
The optional CG 300 grille in robust black metal mesh provide total protection for the subwoofer and an appealing look thanks to the Hertz diamond aluminium logo for better integration into the car.
With the Cento subwoofers even the younger enthusiasts will enjoy an exciting reproduction of low frequencies in the car!

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.

Most Comfortable blanket!
Color: White, Size: Queen(90"*90")
Silky smooth and soft. The smooth side is cooler and good for summer nights while the patterned side provides a little more warmth for cold nights. Have not needed anything else. Works great for me - hot sleeper in Florida with AC at 73 and ceiling fan on. Might have to kick a leg out in the middle of the night or find part of the blanket that is not heated from my body and then I can stay cool. If the AC is turned down just one degree to 72, I stay cool throughout the whole night and sometimes cold. Blanket would probably be too warm at any household temperatures above 74 unless it was FL winter or a colder climate. Nevertheless, it is so comfortable on the skin and easy to move around in.
