How the alternatives compare
Osaki Solo Flex 4D Massage Chair
The Osaki Solo Flex is narrower at 29 inches wide, making it a better fit for smaller rooms than the 32.3-inch Alfine A688. It uses a 4D mechanism and zero-gravity recline similar to the original. However, it lacks the dual-core roller system found in the A688. You also lose the specific 3D foot sole rollers and the memory program feature. This chair relies on automated body scanning rather than the extensive voice control options available on the Alfine. It is a compact alternative for users who prioritize space efficiency over wide seating capacity and advanced dual-roller depth.
HealthRelife 55" SL-Track 4D Chair
The HealthRelife model is significantly lighter at 189 pounds compared to the 291-pound Alfine A688, making it easier to move. It features a 55-inch SL-track and 4D massage, matching the original’s coverage area. However, it does not offer the dual-core 4D and 3D synchronized mechanism. The seating width is 22 inches, which is much narrower than the A688’s 32.3 inches, limiting comfort for larger users. It also lacks the specific lumbar heat therapy and zero-gravity positioning found in the original. This chair suits average-sized users who want full-body air compression and a lighter footprint without the bulk of the Alfine.
MassaMAX MT398 4D Massage Chair
The MassaMAX MT398 offers a 4D mechanism and SL-track similar to the Alfine A688. It is slightly narrower at 29.9 inches wide but provides a spacious cabin experience.

However, it lacks the specific 3D foot rollers and the memory program recall found in the A688. The weight is 208 pounds, making it lighter than the Alfine. This chair is ideal for users who need a wide cabin and voice control but do not require the specialized dual-roller depth or the specific heat zones of the original model.
RELX Mars Pro Large Massage Chair
The RELX Mars Pro has a 53-inch SL-track, which is shorter than the Alfine A688’s track length, potentially limiting full back coverage. It features a 4D mechanism and voice control, similar to the original. However, it lacks the dual-core 4D and 3D synchronized roller system. The seating width is 29.8 inches, narrower than the A688’s 32.3 inches. It includes calf heat therapy, a feature not explicitly detailed for the Alfine. The chair weighs 192 pounds, significantly lighter than the Alfine. This option suits users who prioritize voice control and calf heating over maximum track length and the advanced dual-roller technology found in the original chair.
RelaxRelife 4D SL-Track Massage Chair
The RelaxRelife model features a 53.15-inch SL-track and 4D massage, comparable to the Alfine A688. It supports voice control and app connectivity, offering four control methods compared to the Alfine’s touchscreen and voice options. The width is 29.5 inches, narrower than the A688’s 32.3 inches.
