>It's 945-TL (about 350-USD) after sale. :))

Hmm, any store name that includes ".Concept" means prices are 5x what they should be ;)

That said, could it be:

- Fossilized wood?
- Concrete made to look like wood?
- Rare or exotic wood? For example, my understanding is these days it's pretty much impossible to get a chunk of teak that size
- Salvage wood? For example, in North America a lot of large, first-growth timber was logged then moved via waterways to market or tidewater. Depending on species a percentage of it sank in cold, deep, fresh water and has been preserved. Now some businesses use divers to salvage those logs. This yields wood which is otherwise unobtainable these days

According to Google Translate, the label translates to "the most interesting thing wooden stool".
