The chairs wrapped rope accents are the true focal point of the set. These chairs are comfortable and designed to withstand many weather conditions. The cushions areweather-resistant, but it is recommend that they be stored in a covered location. The round concrete coated topped dining table is perfect for eating meals, chatting with friends and family, and playing cards. This set will stylishly add to those afternoon chats or warm evenings outdoors.
