Does the mattress need to be protected during the trial?
You can just use it as you would any new mattress - and feel free to dispose of the packaging.
It's not a requirement of the trial, but to keep your Simba looking pristine we suggest using a thin mattress protector. We do offer our own, with a fitted design to keep your mattress in optimum condition. It's completely waterproof and acts as a deluxe layer of protection.
