Thank you for submitting your item for appraisal. This appears to be a second half 20th century solid oak Chippendale style carver chair. The backrest is decorated with CNC and hand carved ornaments in the manner of 18th century english furniture. It is a well built chair, but not very old. The estimate is based on similar items actually sold at auction. There is no measurement for the sentimental value you might attach to the item.
