Your Welcome Pack with opening instructions and an opening ‘tool’ is included inside the mattress box. Opening instructions are also on the Mattress Page of the website. You can remove the blue outer wrapper with a pair of scissors that have a rounded point, so they don’t puncture the inner vacuum bag or damage the mattress . The mattress can then be unrolled just like a very large newspaper. NB exercise caution while unrolling as the mattress can unroll quickly if the inner vacuum bag has been punctured.
