Hi EL, really appreciate that you took great pain to educate us. I read from other threads that some buyers encountered peeling and cracking of their full leather sofa after 1-2 years of use. I'm very surprised as I had bought and used 2 sets of full leather sofa for 5 to 6 years without any maintenance and nothing happened. Is it that the so called top grain leather today are not genuine? Btw, I saw your advertisement on Wan Pao yesterday that your company provided 10 years 结构保证 , is it only on structure and mechanism and NOT on leather? Lorenzo sales told me no warranty on leather. If EL do provide warranty on leather, when there is peeling and cracking, is it charged under wear and tear, so not under warranty? IMO (and my experience), if it's a genuine top grain leather, it should not peel and crack in less than 5 yrs with normal usage (unless under direct sun)? Is that true?
