Who should buy which

Pick the OSIM uDream AI, OS-8258 if

Buyers with floor space for a chair OSIM's drawings put at 196 cm (77.17 in) long reclined, who want rollers, airbags, warmth, sound, scent and lighting in one seat, who will run programs from a phone app, and who can accept a weekday curbside drop or pay $450 for White Glove placement.

Skip if

You need a warranty longer than one year or published terms for the frame and motors; you need a stated maximum user weight or height range before buying; you live outside the contiguous US, where OSIM quotes delivery by email; or a 15% restocking fee on a $12,999 return 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.
