We purchased the Deluxe Poly 4' Plain Rollback Swing for our backyard. It appears to be made to last 1000 years. It's easy to put together and is very solidly built. Very comfortable to swing on. We purchased a very similar swing from this company for our front porch 10 years ago and it still looks new. Would highly recommend to anyone looking for a long lasting swing, especially for the outdoors.
This is the second poly swing we have purchased. The other has been out in the weather for 6-7 years and we've never had to even wipe it off. It is comfortable, the assembly instructions are great, and the hardware is exceptional. You will not be disappointed.
