I mainly used a BabyBjorn, but as it became heavier and my shoulders started to hurt, I bought this as a second baby carrier and used them interchangeably. The hip seat distributes the weight to my hips, making my shoulders much more comfortable. I often received compliments on the cute denim blue color of the hip seat. Everything except the hip seat has been cleaned and disinfected. There are faint stains on the areas indicated by the blue arrows in images 4 and 5, but they are barely noticeable. - Model Name: N5 neo - Color: Denim - Accessories: Inner pad, cover, instruction manual - Material: Mesh, cotton - Size: Adjustable Thank you for looking.
