I was looking for a bed rail that would work on multiple beds in my home. Many of the rails on the market are specifically for toddler beds or for twin-sized beds; however, the Regalo Hide Away Bed Rail adjusts to fit twin, full and queen-sized beds. This is ideal for parents, like myself, who co-sleep in a family bed and then move their child straight to a big boy bed.
My husband installed the bed rail in a matter of minutes and said that it was not an issue at all thanks to the very clear instructions sent with the product. One of the things I most admire about the product is its extra-long design, which provides more protection for those within the bed. When installed in the center of the mattress, as instructed, there is only a small about of space remaining on each end of the bed. Even on my son's king single bed, the bed rail provides ample protection. In fact, the space remaining on each end is about the width of a pillow, so by putting a pillow at each end - which I would do any way to keep him from bumping his head on the head and foot boards - he is totally protected.
Additionally, the rail is a lot taller than many of the other bed rails I've seen. When my son stands up on the bed, it hits between his knees and his hips, which gives me peace-of-mind if he should get up in the middle of the night.
One con that I have experienced is a lop-sized bed. When the rail was installed on our queen bed, the installation of the bed rail significantly raised the mattress, putting the mattress at a distinct angle. However, this would not keep me from recommending the product by any means.
