Portable bedside sleeper combines a 38 x 22 x 28 in overall size with a metal frame and linen fabric to keep babies up to 20 lbs within reach from 0-6 months. Seven adjustable heights from 28 to 34 in let you align the top bracket with most beds or create a gentle incline to help reduce reflux and vomiting. Lockable wheels allow you to roll the crib into position and then secure it. Mesh sides improve air circulation and visibility, while a bottom storage shelf holds up to 4.5 lbs of baby essentials and packs into a carry bag for travel.
