Beautifully crafted playpen. Easy to build, is safe and can be thanks to the rollers move well. Our little one loves to touch the beautiful ground rods. Have taken additional mattress, as some suggest, simply be a thick folded blanket on the appropriate size of the pad. Underlay otherwise too hard. (Träumeland mattress in "Other customers also bought" shows up, I had ordered, but took care not at all.) Are very satisfied with the playpen. Would you buy it again at any time.
