A slide assembly and method of assembling a slide assembly are disclosed for use in conjunction with a recreation structure. The slide assembly includes a pair of side rails with internal grooves along lengths thereof and a slide bed located between the side rails with side margins thereof received within the grooves of the side rails. The slide assembly also includes reinforcements extending between the side rails underneath the slide bed, with ends of each reinforcement received within a recess in each of the side rails. Fasteners, such as screws, selectively secure side margin portions of the slide bed and ends of each reinforcement to each of the side rails. The method of assembling a slide assembly includes inserting each side margin of a slide bed into grooves of the side rails and attaching the slide bed and side rails to a recreation structure.
