Alfine A710 Pro
The A710 Pro is Alfine's large-size chair, and it adds an auto calfrest, yoga stretch and over-the-air updates to a 4D mechanism on an SL track. It is rated to about 6'4" and 380 lb. That height is a single figure, so a much shorter user should ask the seller to confirm the fit before ordering.

Who it fits, and who should look elsewhere
A good fit if
- Your tallest user is near 6'4" and your heaviest is under 380 lb.
- You want a 4D mechanism on an SL track with an auto calfrest and yoga stretch.
- Over-the-air updates and a three-year service plan matter to you.
Look elsewhere if
- A much shorter user needs the fit confirmed; only one height figure is given.
- Your heaviest user is over 380 lb.
- You need a stated carton size or door width before you order.

Three things to check first
!
Confirm the height fitAlfine gives one about-6'4" height rating, not a range. Ask the seller how the shoulder and footrest fit a shorter or taller user.
!
Get the carton sizeAsk the seller for the packed carton dimensions before you measure the doorway and the turn.
!
Settle returnsAsk the seller for the return window and who pays return shipping.
