Size A cot that is of high quality is the right size to provide your baby with space to grow without weighing down the nursery. The standard UK cot size is 70cm by 140cm. This should be adequate to fit most babies until they reach around three years old. Some cots could have curved edges or other features that could alter the size of a bed mattress. It is therefore essential to verify your mattress's footprint prior to purchasing. There are many stores on the high street where you can check out an array of cots, including Dunelm and Ikea.
