That is the sofa i have bought and i need to be sure if this pump
any air pump should work,
The football pump is higher pressure (relatively) and lower volume than what you need for your little sofa. A football requires 9 or 10 psi while I would guess you need 3 or 4 psi in the sofa. Plus the needle likely will not fit the fill holes in the sofa. A larger volume pump such as used to inflate rubber boats or camp gear would be faster and easier, and they come with a variety of different sized nozzles.
