100% GOTS-certified organic interlock cotton Our organic cotton cot top sheet is buttery soft and designed to last – even after hundreds of washes. Crafted from luxuriously soft and breathable cotton, this sheet helps regulate your baby's temperature for a comfortable sleep. Its soothing texture is gentle on delicate skin, promoting restful nights. Designed with two fitted bottom corners, it stays securely in place, preventing tangling and ensuring a safe sleep environment. Top sheets are suitable for babies aged 12 months and older, once they are past the swaddling stage and can roll and move freely in their sleep. For younger babies, we recommend using a fitted sheet with a sleep sack or swaddle. Designed to fit a standard cot mattress.
