When it comes to our little ones, safety is of the utmost importance. Moon's Sequr bed rail is to keep your baby safe from bed falls. It is suitable for single mattresses, kid twin beds, doubles, queens and kings. It is also easy to install and open/close; pull on the latch to easily pull down the bed rail. Designed flat iron bars allow your child to be secured safely, without feeling the bars under their mattress. The unique curved pull-down design fits easily around the bed frame.
