I built these chairs with the plans Ana White shared on this site, they are sturdy and beautiful, but they are also heavy. Heavy is what I wanted though.
I used water putty for the screws and other blemishes, then I primed and painted them. when the Homedepot pillows arrived my wife decided she wanted higher backs, I used an idea shared on here, but that back used 2 2x6s, when I tried that I felt they were too high, so I altered it to one, and found they look and feel a lot better. the angle of the back is 15 degrees from 90 or 105 degrees. I will be altering the loveseat plans to build a concrete top bbq coffee table to use with the chairs.
