We'll let you answer this question! The firmness of each Simba pillow can be varied depending on personal preference and all you need to do to switch this up is add or remove the Nanotubes, we even give you a handy bag to keep the spare ones in.
Suggested fill for preferred comfort levels are:
- Firm=640g (entire bag)
- Medium=520g (remove 4-6 handfuls)
- Low=450g (remove 8-10 handfuls)
