Frequently Asked Questions

Got questions? We’ve got answers. Users ask the real questions—here’s what they want to know.

What are the height and weight requirements?
It fits users up to 6'3" tall and supports up to 264 lbs.

You’ll need a doorway at least 32” wide.
What kind of warranty does this come with?

What is the assembly like?
The Osaki Flagship Duo requires some assembly, but it comes with a clear instruction manual and all the necessary tools. The set-up can be completed fast if you are skilled at putting furniture together. You’ll first unbox the chair and begin by taking out the main body. Next, you will attach the side panels. It’s helpful to have 2 people for this part of the job. One person can connect the air and electricity while the other holds the panel in place for the attachments and bolting. The footrest must be attached once the side panels are put in place. This requires connecting the air hose and power, which needs a standard male/female connection and a cotter pin. Lastly, breaking down and recycling the boxes after your installation will be the most challenging part.
Can I customize the intensity of the massage?
Yes! Choose from multiple intensity levels via the tablet or quick controls with 16 Auto Programs & 5 Manual modes.
How far can the chair sit from the wall?
Just 2 inches, thanks to its space-saving technology.
