This chair is composed of a dark, dense cuban/island mahogany of the finest grade. It being an open armed armchair gives it a lightness and the rather tall back is a highly desirable feature.  Compare with the example that Sack shows (see scanned image below).  Note that the legs on ours are turned, as opposed to tapered and this chair does not rely on stretchers, which are cumbersome, and in the better examples, these are omitted, as the strength of these chairs do not require such.  

The scanned example we show is a nearly-matching Hepplewhite lolling chair with the anticipated straight leg configuration.  However, in the same time period, some makers produced the same Hepplewhite forms with rounded legs, perhaps as a design choice, or perhaps as a client preference.   These are rare examples.

As another example of this variation happening in the period, please see the following two items, (also in our collection).  

A Pair of Hepplewhite Heart-Back Side Chairs, New York, c. 1795

A Set of Five Mahogany Hepplewhite Carved Heart-back Side Chairs, New York, c. 1795
http://stanleyweiss.com/item/sw01106

Please note that the overall design of both are nearly identical.  The difference is that the pair has the well-known Hepplewhite spade foot, while the set of five has a much rarer turned and fluted foot.  Both are Hepplewhite pieces. 

Also, note the use of related chairs in a grouping at the White House’s Diplomatic Reception Rooms, where they have been used for decades (see scanned images below).

This is a very desirable form, and there are no breaks or alterations.  It retains an old, dark, historic surface which has been waxed, giving it a deep rich tone.
