Great Service provided by friendly hometown owners! My husband is using a walker. A comfortable chair was brought to him to sit down and Michael walked us out, visited, and helped him into the car. So nice! Thank you!

We appreciate the hasty resizing. They had it down for us in less than 5 hours and at a reasonable price really appreciate the help sizing for both of us as well.
