The Leander collection combines a simple, functional and aesthetic design, while transitioning in functionality parallel with the growth of your child. The oval crib mirrors a child's growth stages from infant to early tween (8-9 yrs. old.)  The unit has four stages: crib (with 2 mattress heights), daybed, transition bed and junior bed.  All needed conversion components are included with the crib packaging. The collection is made of moulded European beech and is surface treated with a water based lacquer.  The mattresses have interior pocket springs for improved comfort and ventilation.  The mattress covers are made of Eco-Tex 100 cotton and are machine washable.
