I originally purchased this item used, so it didn't come with a box or instructions. It also doesn't include a pillow. My children would roll over quickly, so I hardly used it. When I did use it, it was helpful for a little while because it prevented them from rolling over during sleep ^^ As you can see in the photos, you can adjust the width with the Velcro straps, so you can adjust it to fit your baby's body shape and size! It has been washed with adult detergent. I may lightly compress it for shipping. In that case, the shape of the cushion may change slightly. Please understand. Also, I have a cat, so please refrain from purchasing if you are concerned. Product Description ↓ Triangular cushion to support co-sleeping. This is a support item specifically designed for co-sleeping. By adjusting the width, it can be used for a longer period of time, adapting to the baby's growth, overcoming the short usage period of conventional products. The triangular cushion creates a boundary with the baby and supports safe co-sleeping. [Target Age] Newborns to around 12 months [Product Size] ・Approx. W60 x D35 x H13cm (when in use)
