Ikea name of 2-seater sofa bed wanted

Hello dear ones

I have a 2-seater sofa bed from Ikea and unfortunately no name for it.
Even my hours-long Google search yielded nothing :(

On the underside there is only a sticker with the following info:

ID No. 10816 and
509 S017-0

That's it. I took a photo, maybe one of you will recognize it :)

Best regards

Hi :)
I have catalogs up to 1999, and this sofa was not included.
Why do you need the name?
There probably won't be any reference to it anymore, and it doesn't look like a sought-after collector's item either.

Best regards

Wow, almost a rarity already ;D

We no longer need the sofa and would like to sell it.
We bought it second-hand ourselves and
I thought with the name it might be easier.
But if it's that old, probably no one knows the name anymore anyway :D

Still, thanks for your help :D
