Warranty obligation - Ikea Sultan mattresses

Hey everyone, I have a question:

From when did the 25-year warranty on mattresses at Ikea start?

We still have a Sultan Fängebo here that isn’t in great shape anymore and has sagged.
Did the warranty already exist in 2005?
We were told that it probably only started in 2008.
But I can’t really imagine that; we are pretty sure about it.
Maybe someone still has the catalog from 2005 or 2006?
Also as a pdf!?

We still have the receipt.
Thanks for your information....

Cheers, Sanny

Hello,
may I ask which documents these are.
a specific Ikea catalog.

best regards, Sanny

Are you sure they already existed there? How was it with the Family Card at that time?

Oh... The warranty was and still is 2 years. If anything, we are talking about a guarantee of 25 years. Just for your information...

Okay. Why didn't I just buy a mattress from IKEA right away...

That's how you get smarter and a few more backaches richer. But the suffering is over now... :D
