Review on KOOLDOO Toddler Foldable Bedrail Reinforced by Bobby Valadez

The ideal length for a double bed. We use this on the bottom bunk to hold our 2 year old while her older brother sleeps upstairs. It's actually taller/taller than we expected, but that's okay as it can be folded to the side. I attached it to two wooden slats under the mattress but not with the screws provided as they would be too long and would go through the wood which could be dangerous if one of the kids gets under the bed. Also pictured is a 6 inch memory foam mattress.
