Have used this product many times.
We have purchased this or similar products in the past.
On the last 2 occasions the cartons were damaged.
The first one,the damage perforated the canvas inside .
Riot very quickly replaced the damaged one.
The second, most recent one,the carton was damaged and the frame inside was only slightly dented at the back,so I will not bother claiming.
The couriers are very rough with parcels and clearly do not read the instructions.The first badly damaged parcel was left in plain sight of the street,despite a request to leave it hidden behind the flower box next to the front door.The second damaged parcel was also wet at the bottom from being put down somewhere wet.
I think it might help the couriers if the the parcels had strapping for them to grab hold of.Would be interesting to know how common damage is.
