AS this is listed at 23 Kilograms in weight I thought it would be far more substantial than it is.
Sadly the correct weight is 23 pounds so it is 2.2 times lighter than advertised. 
Massive incompetence by Wayfair for making such a serious mistake when posting product details.
Maybe they had a young person write up the details who never learnt imperial measurements at school so does not know the difference!
It might do the job but greenhouse very flimsy and the cover very thin.
