Who should buy which

Pick the OSIM uDeluxe Max, OS-8210 if

Buyers who want rollers, arm and hip airbags, calf and foot massage and back warmth in one chair at $3,499, who have room for a chair OSIM's drawing puts at 179 cm (70.47 in) long reclined, and who can accept a weekday curbside drop or pay $450 for White Glove placement.

Skip if

You want a 4D mechanism, app control or a published heat temperature; you need a warranty longer than 1 year or a stated maximum user weight before buying; you live outside the contiguous US, where OSIM quotes delivery by email; or a 15% restocking fee on a $3,499 return, about $525, would be hard to absorb.

Pick the Real Relax PS6500 4D Zero Gravity Massage Chair if

Buyers under 6 foot 4 and 300 pounds who want a 4D mechanism, zero gravity, and smart controls without a five-figure spend. The 27 auto programs and app control suit households where several people will share the chair.

Skip if

Skip it if you are over 300 pounds or taller than 6 foot 4, or if a 1 year warranty is too short for you at this price.
