Massage Chair Comparison: Brookstone BK-650 vs Synca Kagra J6900

Today we're comparing two massage chairs from well-known and respected brands, the Brookstone BK-650 and Synca Kagra J6900. Both of these are very nice massage chairs but they do have some key differences between them as discussed below.

Not all massage chairs are the same, and the Brookstone BK-650 massage chair and Synca Kagra J6900 massage chair are proof of this. Both are similarly priced, but for the money, you get some big differences.

Depending on your personal preferences, one might work better for you than the other. Is the BK-650's L-track more to your liking, or will the S-shape design on the Kagra J6900 work better for you? Keep reading for our thoughts on each massage chair.

Brookstone BK-650 Massage Chair Top Features

What can you expect from the Brookstone BK-650? Well it has a lot to offer and this article will discuss some of the top features.

3D Massage Rollers

With 3D technology, the chair's massage rollers are able to move side to side, up and down, and in and out. This gives you more control over the massage's strength and depth - especially with four depth levels available to select from.

One-Touch Zero Gravity

With the touch of a button, this massage chair can recline back, bringing your feet above heart level. Why is this important? Poor blood circulation and fluid pooling in the feet and ankles play a role in chronic health conditions like lymphedema and lipedema.

One-Touch Zero Gravity

It is believed that stimulating the flow of blood and fluids back toward the heart is essential for maintaining your health, and the zero-gravity positioning of this chair is thought to make it easy to do as you get your massage.

L-Track Design

There are normally two-track designs for massage chairs: L- or S-tracks (named for their shapes). The BK-650 has an L-track, which follows the curvature of your spine, using the 3D quad style roller mechanism to gently glide over you. It starts at the base of your neck and wraps around under your glutes for a full massage feeling.

Voice Control

You can go into the Google Play or Apple Store and search for Cozzia Voice Commands to find this app. Download and use it along with the speakers, which support both Alexa and Google.

Body Scan Technology

The BK-650 features body scanning technology that will scan the entirety of your back, ensuring that the massage rollers hit all the critical points on your body.

Body Scan Technology

Essentially, this tailors the massage to your body's unique shape. The result is consistent pressure and gentle rolling of the rollers.

Synca Kagra J6900 Massage Chair Top Features

The Synca Kagra is a very well-equipped massage chair as you'll read more about below.

4D Precision Technology

The Kagra J6900 features 4D massage technology, which takes things a step further than 3D tech. This technology allows for pressure adjustments which can help with stress relief in core areas of the body that hold the most tension.

4D Precision technology

It operates in rhythmic horizontal, vertical, and depth motions, allowing you to devise your own custom massage experience. You can do this by choosing any of the manual or automatic massage techniques that you desire. Press the 'memory' button to save this massage for next time if you enjoy it.

Real Body Sensing

The J6900 uses high-performance dual-layer sensors to conduct real body sensing. The system will map out your body's unique contours and you can choose from any of the auto courses, foot massage, or a number of stretch options.

Built-In Bluetooth Speakers

The Synca Kagra boasts a set of integrated Bluetooth speakers that easily pair with your smartphone or tablet for a personalized listening experience during your massage.

It can also play the sound from your smart TV, letting you stream your favorite shows or movies while you relax.

Ergonomic Massage Posturing

Posturing is key for a more impactful massage, and the Kagra J6900's ergonomic massage posturing comes from its adjustable backrest and footrest angles. The armrest will automatically position itself in sync with the backrest's recline in order to be as ergonomic as possible.

Heat Therapy

Heat is a massage essential since it relaxes the muscle groups. The chair's heat pad can stay positioned behind you so as to heat your back, in front of you in order to warm your chest and stomach, or even on your hands in the pocket hand warmers.
