Material is not strong enough for roller wheels. The first day I had it assembled the wheel and groument fell out of the bottom of leg. Spent 3-4 hours trying to repair it with bondo and grorilla glue. I put the wheel assembly back in place and it fell out again. the wooden material is not strong enough for the wheels to roll. I contacted distributor and they said sold out. I have only had this piece for 3 weeks....Sorry this is not professional I need leg replaced.
