Quick verdict
LiftEvidence editorial assessment
A flat-to-85° adjustable bench with a closed ladder adjustment, a 1.57 in seat-to-back gap and a frame that stores upright. It does not decline: the Amazon listing mentions decline, but REP’s published back angles start at 0°.
Most suitable for: Lifters who press mostly flat and incline, value a small pad gap and want a bench that can stand upright after training.
