Recline position that spreads body weight; brands sell it as 2-step or 3-step positions.
The number of steps and the recline angle are brand statements with no shared standard; compare each brand's own wording, do not treat '3-stage' as an equal performance grade.

Brand wording for a roller mechanism claimed to add speed/depth control on top of 3D.
No industry definition was found on the checked pages; the same model can be titled 4D on Amazon and described elsewhere as a 3D mechanism. Record each brand's own wording only, never a cross-brand 4D ranking.

Trade-offs behind these picks: Both models share the same weight rating, so the 4D upgrade is mostly about the mechanism. Only one of the two publishes a recommended height range. Prices move; confirm the current listing before comparing bands. Specs are quoted from the Amazon listing or, where marked, the manufacturer's own page, checked 2026-10-08. Some values on this page come from the manufacturer's own page rather than the Amazon listing; the source type and check date are shown next to each value.
