Okamura: identify the seat version first
Contessa II and Baron are recorded as mesh-or-cushion families in the Kiso Axis library. Okamura's Contessa II materials describe both mesh and cushion seat choices. Identify the version you own before interpreting a catalogue result.
The current flow takes the cautious mesh-review path for those mixed families. Sylphy's library profile starts from upholstered geometry instead. That is a starting category, not a claim that every variant or individual chair has been tested.
Itoki Vertebra03: check the actual upholstered seat
The Vertebra03 profile starts from an upholstered task seat. Use Itoki's catalogue to confirm the exact configuration, then look at the placement of the separate cover on your own chair. Brand reputation does not answer the fit questions.
Check the available flat area, side shape and front edge. The cover should not need to fold or balance across an unsupported area. An unanswered question stays incomplete; uncertainty is not converted into a promising result.
Kokuyo ing: movement makes this a distinct review
Kokuyo presents ing around its gliding mechanism. The library therefore records a gliding-seat construction and starts it in contoured review. Do not transfer a result from an upholstered chair with a different mechanism.
Use the exact-model link below to assess placement. Powered, heated and actively moving seating exclusions still take precedence in the fit flow. A promising result is not a fit guarantee, an allocation or a manufacturer endorsement. Japanese early-access updates are available through the official LINE route.
