This set ( my daughter got the 4 chairs, but I think there was an option for 6) fits beautifully in her house which is very mid century modern. The table was no trouble, but the chairs were another matter! 
Took 3 adults about 2 hours to assemble all 4. The legs are very difficult as you sort of have to bend  compress the wood to get all of the legs into the holes on the seat at the same time.
If you aren’t very mechanically inclined ( I am pretty good as an engineer’s daughter), I would think about professional assembly.
Having said that, once assembled, the chairs are extremely comfortable with good back support.
