Brand: Balance Body Research Institute This item was purchased used. My second child had a strong head-turning preference, and I was concerned about the shape of their head. I used this pillow from December 2022 to around April of the following year, when the baby was between 2 and 5 months old. After that, it was stored in a closet with humidity maintained below 50%. It comes with two winter-use pile fabric covers and two summer-use smooth covers. I only used one of the pile fabric covers after purchasing. I used a bath towel on top of the pillow, so it was not used directly, and there was no spit-up. I will wash it at home before shipping. I considered helmet therapy, but it was too expensive, so I tried this pillow before resorting to that. As a result, the shape of the head improved considerably, and we were able to avoid using a helmet. Why not try it before considering a helmet? It can only be used before the baby starts to roll over strongly. It's better to try it sooner rather than later. There may be some pilling on the covers due to friction from the bath towel, but it is relatively clean. The urethane inside has a slight yellowing, like sun damage, from when I bought it, but there are no problems with its use. The included covers are originally a little small and tight, but they settle down well when the baby is laid on them. This is a used item, so please refrain from purchasing if you are looking for something in the same condition as new. Shipping will be done by attaching the shipping label directly to the original box, which is the same size as the pillow. #FlatHead #HeadShape #CorrectivePillow #Infant
