Comfortable, but extremely bad quality

Had acquired the camping chairs last year and since then used for 2 Camping holidays of one week.
The chair was comfortable and is relatively easy to store.
But from about 6th day of use, the seams went on to the seat. The most severe, the chair may use for person not even weighs 70 kg.

The chair is now no longer usable.
