The assembly was not as difficult for the one seater versus the two seater, which had really heavy parts. However, both products travel when rocking in them. After a few minutes rocking you will have to stand up and place the rocker back in position. I believe this is happening because the legs are not positioned correctly, and I will need to make multiple attempts to get the legs perfectly balanced and straight to keep the rocker from traveling from one side of the other. Kinda a hassle considering the work put in to assemble it.
