I'm camping at Forth Fat. Last night my Exped Synmat started delaminating to the point where it felt like I was perched on a popping Frankfurter

I've used it on probably a hundred and fifty nights. I'm wondering how good their warranty is. A quick squint online suggests they have a five year warranty,

Any experiences with delaminating replacements?

I think it's 5 years on standard stuff and either 2 or 3 on anything with a UL in its name.

I had the Frankfurter issue two.
Mat was about 18 months old. Just sent it back to where I bought it from under warranty.
No issues and a new one sent out 3/4 weeks later.

2 replaced under warranty, not a blink - new ones supplied in a week

Happy days, the importer just delivered a new replacement despite it being outside their statutory warranty period.
