Sorry sir for give you a bad shopping experience. The thickness 1.4 as per demand and no problem for order. Chair load bearing 300kgs. And before loading we have checked all packages well. Because we just deliver as per your demand to your chinese agency address. So whether it bend in transit on sea? Have you asked you logistic agency for loss? If any probelm still welcome you contact ours after sale manager jinyang. And we can help you if you need. How many quantity chairs bend please inform us when you free time. Please don't forget photos. Sorry again and welcome give us 5 star comments.

Thank you!
