The 100% cotton fabric is so soft and breathable, keeping my baby cozy all night long. It feels gentle on sensitive skin, which is exactly what I wanted. It fits our crib mattress (52x28 inches) perfectly with snug elastic edges that stay put. It’s easy to clean, machine washable, and doesn’t lose its softness or color after multiple washes. The pink shade is lovely and works well with different nursery themes. The quality is great, and knowing it’s organic cotton makes me feel secure about its safety for my baby.
