The vibration motor where you sit is very close to surface and you feel the object poking you on right cheek.  Vibration does not really relax me and wish I could buy chair without massage feature.  Lift is really nice.  Motors just make normal whine.  Fedex dropped in my driveway and I had to bring to front door.  Thanks Fedex...not.  Needed pry bar to get back of chair to slide in so more of expert level installation and some knowledge of physics.  Fabric is amazing.  Padding is great everywhere but back of seat.  I don't love it.  However,  I need the power lift feature.  I will add extra pad on the seat and large pillow on back to make more comfy.  My $125 recliner from China is actually more comfortable to sit in but hard to get out of chair and arm rest has no padding on it.  China is known for one glaring missed detail usually, and the seat may be it for this chair.
