"Nicky, thank you so much for following up-- even though I have automatic-reply stuff on my website I know it takes occasional effort, too! We received our bed-rails today. Busy with my parents, we haven't unpacked them or installed them yet. But we were all amazed they got here so quickly. Thank you very much for your help. I've got a feeling we'll be in touch for further items and advice. God Bless"— Edie
