Lessons to be learnt:

1. Do not neglect the underside of the mattress specially if you are still using flip-able ones. 

2. Planks supporting the mattress can still scratch your mattress and it might be good to put an old mattress cover on the underneath side 

3. Beware of kids as they tend to have less control over their pee (accidents do happen to adults too) and love the joy of jumping up and down on the mattress (openly or secretly).

4. Menses is also an enemy that can be unpredictable at times even if you are using the best app to keep track of them.

5. Sometimes we love to work on our bed but just be careful where you placed your pens.

Are you ready to take good care of your mattress in the next 15 years?
