I learnt a lesson with this purchase and will not buy a set of garden furniture 'blind' again.
I bought two 1.2 m round tables and eight folding armchairs. On the website, Teak Warehouse give the width of their Thames Folding armchair as 55cm and the height as 98cm, giving the impression of a decent sized chair.
Buyers should be aware that in reality the chairs are quite small. We felt they were more suited to children or small adults and would not have ordered them if we had known.
I have measured them and the 55cm width is to the outside edge of both arms. The internal width or sitting gap is much less at 44cm. The size of the slatted seat is a small 38cm wide and 37cm deep. The cushions provided with the set are bigger than the seat and project in front of it. The height is 89cm not 98cm as stated on the website.
You always take a chance buying something you haven't seen. With such a variety and variability of garden furniture around it is much better to look and try before you buy. Even if it costs more, you will avoid disappointment and a feeling that you have wasted your money.
