yep, its not an offence to move a sofa around by hand in a public place.
TBH in this case most rentaguards / cops would assume its a student prank or something for youtube and ignore it unless someone actually complained.
unfortunately Ipswich is a pokey narrow town with little free space, plus some of the people I know in town seem to barely have the motivation to move their own rig let alone cart a heavy sofa through town. And in the only place you could put it the market traders would grass you up within seconds, they even made the council move the town Christmas tree!
