There is no difference, what you must take into account is the size of the cot, since the measurements of the mattress will not be the same for a 70x140cm cot or convertible crib as for a 60x120cm one. Also, keep in mind that when a convertible crib is transformed into a nursery, the mattress measurements for the bed will change. In the specifications of each cot on our website you will find the measurements, as depending on the model, some details may change.
Our visco mattresses are the mattresses that we include in case you decide to order them together with your convertible. Very comfortable, they have a soft touch and a foam base, with the adequate firmness to favor the correct development of the baby's spine in the first years. On the other hand, being highly breathable, they greatly facilitate air circulation and, therefore, make the temperature for the little one perfect.
For their part, our organic mattresses with soy extract are the most sustainable and current option, and of the highest quality, in our catalog. Made with hypoallergenic and highly breathable materials, they also prevent allergic reactions or problems caused by bacteria.
You should choose a mattress with the thickness that the lower bed base allows. In our case it is a maximum thickness of 22cm. The most convenient thing is that it measures 90x190x22cm so that, when removing the drag from the lower part, it is not blocked.
