The Marcy 3 in 1 Smith Machine is a home gym frame that puts a Smith bar on linear ball bearings together with upper and lower dual cable crossovers, an adjustable bench with six backrest angles and four seat heights, a multi-grip pull-up bar and dip bars attached to the frame. It sits at number 2 in this guide at £899.00, rated 4.5 out of 5 from 179 ratings, and it weighs 54.5 kg.

What this listing cannot agree with itself about is size. The Item Highlight puts the cage at 154 x 180 x 218 cm; the item dimensions field on the same page says 1.85 x 2.18 x 2.16 metres, which is 185 x 218 x 216 cm. None of the three measurements matches the other set. The title also sells an adjustable bench, and the bullets describe its backrest and seat, but the Included Components field lists only a power tower, a manual and tools. Its own numbers for tension do line up on the other hand: 600 lbs, 600 pounds and 272 kg are the same figure written three ways. Everything on this page is taken from the Amazon listing for the Marcy SM-4903; we have not assembled or tested it ourselves.
