With 32 airbag points and customizable zero gravity positioning, it offers a structured approach to relaxation.

What stands out

Who it fits
Good fit for
This chair suits users who want deep, targeted relief without leaving their home. The large size and 55-inch track accommodate taller frames better than shorter models. If you value customizable pressure levels and specific heat zones for your lower back and calves, this setup delivers. The zero gravity feature also benefits those seeking improved circulation or spinal decompression after long days. The AI voice control adds convenience for users who prefer minimal remote interaction.
Who should skip it
You might look elsewhere if you prefer a compact footprint. At 66 inches long and 192 pounds, this chair requires significant floor space. If you are sensitive to the intensity of 4D rollers, the deep-tissue focus may feel too aggressive. Additionally, if you do not value voice commands or music integration during sessions, the AI and Bluetooth features add complexity you may not need. Smaller rooms or users under 5 feet tall may find the SL track coverage excessive.
Verdict: The RELX Mars Pro Large offers a robust, spec-heavy massage experience with extensive coverage and customizable intensity. It is a strong choice for those prioritizing deep tissue relief and full-body tracking in a spacious home environment.
Key specs explained for this chair
Massage Mechanism: 4D
A 4D mechanism means the massage rollers move in four dimensions: up and down, left and right, in and out, and forward and backward. This allows the chair to adjust the depth and speed of the massage in real time. You get a more dynamic and varied experience compared to standard 2D chairs. It helps target specific muscle knots with greater precision, making it suitable for users who want deeper, more customizable relief rather than just a simple kneading motion.
Track Type: 53-inch SL track
An SL track curves along the spine to cover both the lumbar and shoulder areas, extending down to the glutes. A 53-inch length ensures the rollers reach from your neck down to your upper thighs. This wider coverage is ideal for taller users or those who want full back support. It provides a more comprehensive massage than L-track chairs, which often stop at the lower back, ensuring you get relief across the entire posterior chain.
Reclining Function: Zero gravity
Zero gravity positioning reclines the chair to a neutral angle that reduces pressure on your spine and improves blood circulation. This position mimics the weightlessness felt in space, allowing your muscles to relax more deeply. It is particularly beneficial for users with back pain or those seeking ultimate comfort. By distributing your body weight evenly, it enhances the effectiveness of the massage rollers and airbags, making it a key feature for stress relief and spinal health.
Heat Therapy Zones: Lower back and calves
This chair includes heat therapy specifically for the lower back and calves. Heat helps soothe tense muscles and improves blood flow to these areas. The lower back heat targets common pain points from sitting, while calf heat aids in recovery after standing or walking. This targeted approach is more efficient than full-body heating, which can be overwhelming. It allows you to focus on specific sore areas, providing gentle warmth that complements the mechanical massage for deeper relaxation.
Design and build details
The RELX Mars Pro Large arrives in a black finish. According to the listing, this unit measures 29.8 inches wide, 44.5 inches high, and 66 inches long. It weighs 192 pounds. These dimensions place it in the large category. You will need ample floor space to accommodate its footprint. The substantial weight suggests a sturdy internal frame, though the listing does not specify the exact materials used for the exterior shell or upholstery. This size ensures the chair can support a wider range of body types while maintaining stability during operation.
The layout centers on a 55-inch SL track. This track extends coverage by over 50% compared to standard L-tracks. It is designed to fit body curves from the neck down to the thighs. The chair includes zero gravity reclining. This function adjusts your posture to reduce spinal compression. You can customize the position to find a comfortable angle for relaxation. The design also incorporates far infrared heating zones for the lower back and calves. This targeted heat helps soothe muscles during use.
Controls are handled via AI voice commands and a Bluetooth speaker. You can issue verbal demands to start specific programs without using a remote. The built-in speaker allows you to listen to music while receiving treatment. This setup frees your hands and simplifies operation. The foot section features full-roller kneading. This mechanism stimulates acupoints in the soles. The combination of voice control and integrated audio creates a streamlined user experience focused on convenience and immersive relaxation.
Setup and everyday use
The RELX Mars Pro Large requires significant floor space due to its 66-inch length and 29.8-inch width. You will need room for the chair to recline fully into its zero gravity position. The unit weighs 192 pounds, so moving it during initial placement may require assistance. Once positioned, you can begin using its extensive feature set immediately.
Daily operation is controlled via AI voice commands, which allows you to start programs without touching a remote. The chair also includes a Bluetooth speaker, enabling you to stream audio directly from your device during sessions. You can choose from 15 auto modes or 5 manual modes to adjust the intensity.
The 55-inch SL track covers your back from neck to thighs, with intelligent shoulder detection to ensure the rollers align with your body curves. For lower body care, the foot rollers provide full kneading, while airbags target your calves. You can activate far infrared heating for both your lower back and calves to ease tension.
The yoga-style stretching function reclines the backrest to relieve lower back discomfort. The chair offers 32 airbag points with five pressure levels, allowing you to customize the squeeze intensity. The zero gravity recline reduces spinal compression and enhances circulation. These specs suggest a straightforward interface for accessing full-body relief in your home environment.
Owning the RELX Mars Pro
This chair is a substantial piece of equipment. At 192 pounds, you need a sturdy floor that can support the weight without slipping. The zero gravity function reclines the unit, so you must ensure there is clearance behind your sofa or wall. The listing notes Bluetooth speakers, so you should check your phone’s compatibility with standard audio protocols. You will also want to verify that your home’s electrical outlets are grounded and accessible, as the power cord length is not specified. For upkeep, regular dusting of the black vinyl is necessary to prevent cracking. This model sits alongside other full-body recliners in our 1 options. It appeals to buyers who prioritize extensive track coverage and voice control over compact designs. Consider your daily routine and space constraints before adding it to your spa equipment collection.
