The chair arrived a day earlier than scheduled and delivery instructions had not been passed onto driver.
The chair itself was easy enough to assemble although the instruction page was laughably poor.
Chair back is not as tall as advertised.
Massage and heat functions work well and massage motors do not intrude into chair seat or back so it is a comfortable chair for sitting for long periods.
I like the swivel facility and the well weighted rocker.  
I am very pleased with my choice and had the chair arrived with proper instructions it would have got five stars.
