To measure is to know
First of all, it is good to know that the DOUXE fitted sheet can be used for several types of mattress and mattress combinations. Our fitted sheets have a corner height of 45 cm, all mattresses from 5 to 45 cm can be fitted with our fitted sheet. The strong elastic border pulls the fitted sheet tightly under the mattress. This makes it a perfect fit for thick mattresses or combinations of mattress and topper, but also for a topper alone. Our advice is to always add a protective layer to protect the mattress against dirt. This can be done with a molton fitted sheet or a plate. You then put the fitted sheet over it.
Secondly, it's not complicated which size or which fitted sheet to choose. It's basically just the same size as your mattress. If you have a mattress of 180x200, then you need a fitted sheet in the same size.
