FAQ

Is it normal to sleep poorly as a couple?Yes, it's common and a matter of adaptation, not a sign of romantic failure.
Does a duo mattress solve all problems?Not always, but it is often an excellent first solution.
What if my partner snores a lot?A medical consultation may be necessary. Nasal strips or specific pillows can help.
Can we sleep in separate beds without harming intimacy?Yes, it can even enhance quality of life and closeness.
How to choose the right mattress firmness when both partners have different preferences?The ideal solution is a duo mattress, made up of two half-mattresses of distinct firmness levels assembled under the same fitted sheet. Each partner thus benefits from support suited to their body type and sleep habits. If the budget does not allow for a duo mattress, a mattress topper on one side can compensate for a difference in preference at a lower cost.
