A picture frame unit comprised of a main front frame together with a one-piece retainer as a backing for the unit. The edges of the retainer snap into the frame causing a number of integral spring biased pads to press against the back of the picture placed within the unit. The snap-in mechanism secures the retainer into the back of the frame while the retainer pads secure the picture into place within the unit.
