How to choose the right mattress size and which mattress brand is the best? I need help, please.
It depends on how big you are and if you sleep alone or with a partner.
I would go for a standard size 203x168cm (80"x66"), altough lots depends on the room you are sleeping in. In extend to that the comfort of the mattress and desired parameters about stifness,… is also something not to forget (!).
For choosing the right brand there are some brand reviews available online depending on your country.
Good luck on finding your perfect fit .
