I've heard from several clients over the years that their Kitchen chairs are a little too short to be comfortable at the table. They feel like little kids sitting at the grown-up table. We had the same problem at our house!
The answer is to reupholster your chairs using thicker foam on the seat. We like our Kitchen chairs, above. They're by Amisco and made of white metal. The cheery floral fabric on the seats wore well for a number of years, but then just looked dirty, so I decided to reupholster the pads myself and finally raise them up with thicker foam to get a better height. Big mistake.
The mistake was thinking that I could do the job myself. I didn't take a picture of the messy side of my work, you'll just have to believe me when I say they looked like a child had done the job. If you look closely, you'll see some lumpy stuff going on because I made every mistake in the book. After wrestling with 3 out of the 4 chairs, I didn't have the heart to go on, so left the 4th in it's original state, dirty fabric and all, and stepped away from the project. For about 2 years. What can I say? Time flies.
They're finally fixed and looking great.
A short time ago I discovered Revolution Performance Fabrics, made right here in the USA. This fabric is bleach cleanable, well priced and comes in all sorts of nice patterns and colors. I used their Ombre pattern in the Flannel colorway. Off the chairs went to my oh-so-awesome upholsterer and they returned looking as you see above. Fantabulous. Tailored. Bleach cleanable (that bears repeating).
And with 5" foam on these seats, we sit high and proud at our table. Very comfy!
