Nifty用 ベッド変換キット（幼児用）

We needed a rail that wouldn't wobble, and this one clicks right into the existing crib frame with zero leftover parts. My son loves being able to get in and out by himself now.

The conversion took about 10 minutes with just a screwdriver, and the rail sits low enough my kid can get in and out safely but still stays put at night. It's exactly the right length at 52.25 inches to match the crib frame, so no wobbling.

My toddler was starting to climb out of the crib, so I grabbed this conversion kit to switch to the toddler bed setup. The rails fit perfectly onto the existing frame, and the 52-inch length gives plenty of room for my little one to stretch out without feeling confined.
