The Serenity 2D Zero Gravity Massage Chair is designed for people who want a relaxing full-body massage at home without spending time visiting a massage therapist. It combines 2D massage rollers, a zero-gravity reclining position, air compression, and heat therapy to create a comfortable massage experience.
Unlike a 3D massage system, which can adjust how far the rollers extend toward your body, a 2D system moves the rollers vertically and horizontally along the massage track. This provides a straightforward massage experience, although it offers less control over roller depth.
The Serenity 2D Zero Gravity Massage Chair also includes several features that are commonly found in more advanced massage chairs, including body scanning, Bluetooth speakers, and foot rollers.
But is this massage chair worth considering? Let’s look at its manufacturer, dimensions, features, and limitations so you can decide whether it fits your needs.
Who Makes the Serenity 2D Zero Gravity Massage Chair?
The Serenity 2D Zero Gravity Massage Chair is sold under the Best Massage brand. The model listed by Costco is BM-EC-8730.
It is important not to confuse this chair with products made by Human Touch. Although Human Touch is a recognized massage chair company, the verified Serenity 2D product listing identifies Best Massage as the brand.
The chair is designed to provide a full-body massage through a combination of mechanical rollers and air compression. It also includes a reclining position intended to make the massage more comfortable.
Before purchasing, check the exact model number on the product listing. Massage chairs with similar names may have different features, specifications, or warranties.

Features of the Serenity 2D Zero Gravity Massage Chair
The Serenity 2D Zero Gravity Massage Chair offers several comfort and convenience features. Here is how each one works and what you can expect from it.
1. 2D Massage Roller System
The chair uses a 2D massage mechanism that moves rollers up and down and from side to side along the massage track.
These movements are designed to imitate common massage techniques and provide pressure along the back.
A 2D system may be suitable for people who prefer a straightforward massage without extensive roller-depth adjustment.
However, you cannot independently control how far the rollers extend into your back the way you can with a chair that offers adjustable 3D massage depth.
2. SL-Track Massage System
One of the important features of this chair is its 53-inch SL-track.
The track follows the natural curve of the back and extends toward the seat area. This allows the rollers to travel farther than those in many traditional short-track designs.
The longer track may provide a more complete massage experience across the back and toward the gluteal region.
However, the coverage depends on your height, seating position, and how well the chair fits your body.
3. Zero-Gravity Reclining
The zero-gravity feature is designed to place your body in a reclined position with your legs elevated.
This position distributes your weight differently across the chair and may make the massage feel more comfortable.
The BM-EC-8730 model is listed with two zero-gravity stages, allowing you to choose between reclining positions.
Keep in mind that zero gravity is a comfort feature. It should not be considered a treatment for spinal injuries or other medical conditions.
4. 42 Airbags for Compression Massage
In addition to its mechanical rollers, this chair uses 42 airbags to provide compression massage.
The airbags inflate and deflate around selected parts of the body, creating a squeezing sensation.
This can feel relaxing, particularly after sitting or standing for long periods.
The chair includes three air-pressure intensity levels, allowing you to select a comfortable setting.
If the compression feels too tight, reduce the intensity rather than continuing with uncomfortable pressure.
5. Heat Therapy
The Serenity 2D includes a carbon fiber heating feature intended to add warmth during a massage.
Gentle heat may help some people feel more relaxed, particularly when their back muscles feel stiff.
However, heat should be used carefully. Avoid prolonged exposure, and do not use the heating function over injured or swollen areas unless a healthcare professional advises it.
People with reduced skin sensation should seek medical advice before using heated massage equipment.
6. Six Automatic Massage Programs
The chair comes with six preset massage programs.
These programs allow you to select a massage routine without manually adjusting every setting.
Automatic programs can be convenient for people who simply want to sit down, relax, and start a massage.
However, the strongest program is not necessarily the best choice. Begin with a comfortable setting and adjust it according to your needs.
7. Five Massage Techniques
The Serenity 2D offers five massage techniques, allowing you to experience different roller movements.
Depending on the selected program, the chair can combine movements intended to create sensations similar to kneading, tapping, or rolling.
This variety helps prevent every session from feeling exactly the same.
The chair also offers three massage-speed settings for additional customization.
8. Foot Massage Rollers
The chair includes mechanical foot rollers designed to provide massage along the soles of your feet.
This feature may be particularly enjoyable after spending several hours walking or standing.
However, strong pressure on the feet is not suitable for everyone. People with diabetic neuropathy, poor circulation, foot ulcers, or other significant foot conditions should seek medical guidance before using this feature.
9. Bluetooth Speakers
The Serenity 2D Zero Gravity Massage Chair includes Bluetooth speakers.
You can connect a compatible device and listen to music or other audio while relaxing.
The Bluetooth function is a convenience feature rather than an essential part of the massage mechanism, but it can make the experience more enjoyable.
10. Body Scanning Technology
Another useful feature is the chair’s body scanning system.
This technology is designed to help the chair position its massage rollers according to the user’s body.
Proper alignment is important because rollers that press against the wrong area can feel uncomfortable.
Always check that the massage mechanism fits your body comfortably, even when automatic scanning is enabled.
11. Zero-Wall Design
The chair features a space-conscious zero-wall reclining design.
This allows the chair to recline while making more efficient use of the space behind it compared with some traditional recliners.
However, zero-wall does not mean the chair can be placed directly against the wall.
Check the manufacturer’s clearance requirements and measure your room before purchasing.
12. Remote Controls
The model includes an LED remote and an additional built-in armrest control.
These controls make it easier to select massage settings, adjust intensity, and operate supported functions.
The armrest control can be particularly convenient when you want to make a quick adjustment without reaching for the main remote.
Serenity 2D vs. 3D Massage Chairs: What’s the Difference?
If you’re comparing massage chairs, one of the biggest decisions is whether to choose a 2D or 3D massage system.
| Feature | 2D Massage | 3D Massage |
|---|---|---|
| Roller Movement | Up/down and side-to-side | Up/down, side-to-side, and in/out |
| Roller Depth Adjustment | No independent depth control | Available on compatible models |
| Massage Customization | Basic to moderate | Generally more adjustable |
| Price | Often more affordable | Often more expensive |
| Best For | People wanting straightforward massage functions | People wanting more control over roller depth |
A 3D massage chair is not automatically better for everyone. Some users prefer the simplicity of 2D massage, while others appreciate being able to adjust the depth of the rollers.
The overall comfort also depends on the chair’s design, body fit, massage programs, and pressure settings.

Is the Serenity 2D Zero Gravity Massage Chair Worth Buying?
The Serenity 2D Zero Gravity Massage Chair may be worth considering if you want a full-body massage experience with several comfort features.
Its combination of an SL-track, air compression, heat therapy, foot rollers, and reclining positions makes it more versatile than a basic massage chair.
However, this model may not be the right choice if you specifically want independent roller-depth adjustment or a chair with a higher weight capacity.
Before buying, consider the following:

- Body fit: Check the recommended height and weight limits.
- Massage preferences: Decide whether 2D rollers provide enough adjustment for your needs.
- Warranty: Confirm the current coverage and available service support.

- Price: Compare the actual selling price with other massage chairs offering similar features.
It is also important to distinguish the original Serenity 2D model from newer Serenity Deluxe models, which may have different controls, massage programs, and dimensions.
How to Use the Serenity 2D Massage Chair Safely
A massage chair should make you feel comfortable rather than cause pain.
If you’re using the Serenity 2D for the first time, begin with a gentle massage setting and a short session within the manufacturer’s recommended operating time.
Adjust the seating position and make sure the massage rollers align comfortably with your body.
Do not continue using the chair if you experience sharp pain, excessive pressure, numbness, tingling, or unusual discomfort.
If you have severe osteoporosis, a recent injury, a bleeding disorder, or another condition that could make massage unsafe, consult your healthcare provider first.
Remember that massage chairs are intended primarily for relaxation and comfort. They should not replace medical treatment for an injury or persistent pain.
