There are (contrary to a previous review) only (still) 4 screws that have to be mounted. This is within 10min. done and you can loll around on a beautiful deck.
I had no problems with a non-existent thread, even with the provision of the 4 screws. It keeps everything bombproof and looks very good.
Class deck with extravagant design - I'm glad I did not let myself be influenced by the negative reviews.
Thank you!
Addendum: The deck height itself is between 33-35cm.
