The changing table is larger than most other which allows me to use for my big as it is easy to fit and practical with its 4 wheels brakes. The mattress that fits him is a bit expensive (count 25 euros), one can use a standard but considering the size of the plan, it is better to have the Geuther if you do not want it to slip. This is a good quality product, the 2 floors can store layers & various products. Anyway, I'm satisfied with my purchase!
