BOSSCARE GR8602 4D
4D SL-track triple zero-gravity · Reviewed by Drew · amazon.com live, Sept 28 2026
Why it scored a 77
At $1,699 the BOSSCARE GR8602 is the most feature-dense chair under seventeen hundred dollars here: 4D rollers, 36 airbags, three-stage zero gravity, a Thai stretch, app and voice control. Features lead at 84 and value sits at 80, while quality trails at 60. The catch is support and polish — BOSSCARE is an Amazon-native import brand with about 400 reviews, the three-year warranty explicitly covers the motor rather than everything, and owners report a fiddly app, noisy pumps and a stretch that pulls hard on the legs. It suits a spec-hunter who skips flagship pricing.

Should you buy the BOSSCARE GR8602 4D?
The BOSSCARE GR8602 4D is for the buyer who wants 4D rollers, a stretch program and lumbar heat in one chair without crossing $1,700. It lands third in our massage-chair ranking at $1,199.00, the same price as the HealthRelife HR337 4D, and the two are close competitors. The GR8602 gives you lower-back heat, AI voice control and a breakaway tablet remote; the HR337 gives you a longer track and four more airbags. Skip both and buy the Real Relax Favor-06 if you want to stay under $1,300.
Where it earns its score
- Feature density. 4D rollers, 36 airbags at three intensities, dual foot rollers, 12 auto plus 6 manual modes and a Thai stretch program, all for $1,699.
- Lumbar heat that is actually specified. BOSSCARE lists 40 to 45 C at the lower back, which the HR337 does not offer at all.
- Three ways to control it. App, voice and a detachable tablet remote, so you are not stuck with one interface.
- Three-stage zero gravity with a long legrest. The legrest extends to fit users around 6'2".
What to know first
- Quality is the lowest factor at 60. Reports of pump noise and app frustration mirror what we see on the HR337.
- Warranty covers the motor. Three years on the motor, but coverage of other parts is not stated. Ask before you buy.
- Lower capacity than some rivals. 330 lb stated maximum, versus 400 lb on the Favor-06.
- It is heavy. 184 lb chair weight, so plan for two people and a clear path on delivery day.
Our verdict
The GR8602 4D scores 77, Fair Buy, two points behind the HR337 at the same price. Buy the BOSSCARE if lumbar heat and voice control matter to you; buy the HealthRelife if track length and airbag count matter more. Either beats the RELX Mars Pro on value at $1,200 less.
