The twin bunk beds that served our twins well are available.
We bought them years ago from Crate and Barrel and they are in excellent condition. Solid Ash with a clear lacquer finish. Twin Bunk beds, includes Ladder and Guard Rails. Best offer and pick up only. Anyone interested, kindly leave me a comment or e-mail me on my site at pve contact above.
My apologies, I rarely would do this type of thing, but there must be a set of twins or siblings who would love these as much as our sons did.
