How these models differ from the M505
HealthRelife 55" SL-Track 4D Chair
The HealthRelife 55" SL-Track 4D Chair is smaller than the Medfinity M505, measuring 22 inches wide and 35 inches deep. It weighs 189 pounds, making it lighter than the M505 at 206 pounds. This chair keeps the same 55-inch SL track and 4D mechanism for similar massage coverage. However, it relies on a physical remote and Bluetooth audio instead of voice commands. You should choose this alternative if you prefer traditional controls and want a more compact footprint for average-height users who do not need the larger cabin of the M505.
RELX Mars Pro Large Massage Chair
The RELX Mars Pro Large Massage Chair is significantly taller and longer than the M505, with a length of 66 inches compared to the M505’s 40 inches. It weighs 192 pounds and features a shorter 53-inch SL track. This model includes distinct voice control and calf heating, which the M505 does not list. The heavier build and extended length make it less ideal for taller users seeking maximum track coverage. Select this option if you prioritize hands-free voice interaction and targeted calf warmth over the longer spinal coverage provided by the M505.
RelaxRelife 4D SL-Track Massage Chair
The RelaxRelife 4D SL-Track Massage Chair is larger than the M505, measuring 60.2 inches in length and 29.5 inches wide. It weighs 200 pounds, slightly less than the M505. This model offers smart home integration and automatic body scanning, matching the M505’s auto-scan feature. It provides app and voice connectivity for full-body reclining. If you want deeper smart home connectivity and automatic scanning without the specific pinch guard airbag system of the M505, this chair is a suitable alternative for users who prioritize app control and voice commands.
HealthRelife V3 4D Massage Chair
The HealthRelife V3 4D Massage Chair is shorter than the M505, with a length of 35 inches versus the M505’s 40 inches. It weighs 198 pounds and features a 40-inch height. This model focuses on deep tissue massage and extreme recline angles, differing from the M505’s emphasis on airbag compression. It lacks smart app integration, relying instead on physical comfort features. Choose this alternative if you value deep tissue rollers and near-flat recline positions over the voice control and extensive airbag coverage found in the Medfinity M505.
EZsport 4D Airbag Massage Chair
The EZsport 4D Airbag Massage Chair is larger than the M505, measuring 66.2 inches in length and weighing 205 pounds. It includes back heat and a touch screen, adding warmth features not listed for the M505. The chair uses 4D rollers and airbag massage for full-body coverage. It is designed for buyers who want targeted back warmth and deep tissue massage in a standard-sized home. If you prioritize back heating zones and a larger cabin size over the specific pinch guard technology of the M505, this model offers a compelling alternative.
MassaMAX MT398 4D Massage Chair
The MassaMAX MT398 4D Massage Chair is larger than the M505, with a length of 64.6 inches and a width of 29.9 inches. It weighs 208 pounds, making it slightly heavier. This model provides comprehensive airbag coverage and voice control, similar to the M505. It features full-body stretching and heating zones within a spacious cabin.

The RelaxRelife model also offers a long 60.2-inch track, providing extensive coverage for taller users seeking full-body reach.
Are there options with voice control like the M505?
Yes, several alternatives include voice control capabilities. The Medfinity M505 itself uses voice commands, and the RELX Mars Pro Large also offers distinct voice control for hands-free operation. The MassaMAX MT398 and RelaxRelife models similarly integrate voice connectivity, allowing you to adjust settings without using a physical remote or touchscreen interface.

Yes, several models provide back heat. The EZsport 4D Airbag Massage Chair specifically highlights back heat for targeted warmth during deep tissue massages.
