Thank you for viewing my listing. This is one bed guard (one side) measuring 190cm. I purchased these several years ago, and I bought two. One has remained unopened. The first and second photos are of the opened one, which I used when listing it. The item I will send is unopened. It is designed to be placed between the mattress and the bed frame. It had a sturdy construction, so I used it without the included screws or tape, without fixing it in place. A Japanese instruction manual is also included. Please understand that this item was purchased several years ago before considering a purchase. Thank you.
