The Shadow-8 Dual Motion Actuator is designed for those who demand the very best. It adds an unbelievably accurate, powerful, and uniform tactile effect to all types of chairs and couches. For those home theatre enthusiasts who require high power output and have the highest standards, the Shadow-8 Dual Motion System is a necessity.
The Shadow-8 performance remains true to the artistic content of movies and music. It delivers the low frequency content in an accurate, natural and powerful way.
The Shadow-8 Actuators can be installed by a person with no mechanical skill in less than 15 minutes. No modifications to furniture or flooring are required. The system easily interfaces with standard audio equipment using conventional audio signals.
The Shadow-8 Dual (T108SS) includes :
- 2 Shadow-8 Linear Actuators - The Shadow-8 Actuator is a patented electromagnetic motor specifically designed to deliver extraordinarily accurate low frequency motion to a wide range of furnishings. The Shadow-8 is part of the same family as the original TES100. The Shadow-8 shares the same famous quality and reliability but delivers improved performance especially when producing infrasonic frequencies (below 20Hz). The Shadow-8 has a new magnet structure with a vented centre pole to allow air to move in and out more efficiently. The Shadow-8 also sports a new 8 ohm drive coil and an increased range of motion. The Actuator is constructed with the highest standards. From rare earth magnets to grained and anodised aluminum, the Shadow Actuator is pure quality.
- 2 Motion Isolators - The Motion Isolators dramatically reduce the amount of tactile motion transmitted to the floor and surrounding environment. They effectively isolate the tactile sensation to the couch or chair. The Motion Isolators are made of a high quality mark-free rubber.
The Shadow-8 Dual (T108SS) requires:
- Amplifier - We highly recommend: the Crowson D-501 Tactile Motion Amplifier. Third party amplifiers may work to power the two (2) Shadow-8 Actuators but require the addition of a Bass Management Pre-Amplifier. We recommend a DEDICATED amplifier that can produce 50 to 500 Watts per channel with an 8 ohm load. It is also useful to have volume or gain control and line level pass throughs.
- RCA Y adaptors and cables - RCA male-to-two female Y adaptors may be necessary if your amplifier does not feature line level pass throughs. Standard audio RCA cables can be used. In many cases a two channel cable can be separated to yield two mono RCA cables. (See installation manual for specific requirements.)
- Speaker wire - Standard audio speaker wire should be used to deliver power from the amplifier to the Shadow-8 Actuator. We recommend wire size 18 AWG or larger.

This topper has definitely provided me with better, more comfortable sleep.
Color: Green, Size: Twin
I recently tried a twin mattress topper made from bamboo-derived viscose, and I'm quite impressed. The topper is thick, waterproof, and offers excellent comfort, especially for those who struggle with back pain or sleep hot. The bamboo and polyester blend gives it a soft, cooling surface that's perfect for a restful night's sleep without the sweaty feeling often associated with memory foam.
What I really appreciate is its dual function. It's breathable, allowing for good air flow, and fully waterproof, which helps keep the mattress underneath safe from spills. This is especially useful if you have kids or pets.
The topper's thickness is just right—it provides great support without feeling too soft or too firm. It cradles pressure points well, offering relief to my hips, back, and shoulders.
The fluffy filling holds up well over time, maintaining its softness and support. It fits securely on mattresses, thanks to a deep pocket skirt that prevents any sliding or bunching. This topper has definitely provided me with better, more comfortable sleep.

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.
