Butterfly Back Occasional Armchair – Engineering Specification Overview
Engineering Logic
The engineering intent is to address Joint Fatigue within this Butterfly Back Occasional Armchair typology.
The split-back configuration acts as a double cantilever; when a user leans back, the stress is concentrated at the junction between the floating back pads and the seat rail. This is addressed through the OE-Lock™ Multi-Axis Joinery System, which operates by anchoring the central spine deep into the rear apron while allowing micro-flexion in the upper wings.
OE-Lock™ denotes an internal joinery configuration family. This represents one of several possible structural mitigation strategies, selected based on projected usage intensity.
Review engineering protocols on lifecycle fatigue and long-term calibration.
As a result, the risk of backrest fracture or loosening is mitigated under one calibrated hospitality scenario involving cyclic public loading.
Crucially, this structural density is engineered into the core matrix to limit degradation without reliance on visible external bracing.
Butterfly Back Occasional Armchair – Aesthetic Structure
Designed as a controlled study of proportion and material behaviour, the Butterfly Back Occasional Armchair maintains architectural discipline.
The visual lightness of the “butterfly” wings contrasts with the grounded stability of the cabriole legs. The tufting pattern is calibrated to align with the curvature of the frame, ensuring the leather tension reinforces the padding structure. This unit aligns with the ornamental logic of the Rococo Royal Collection.
Project-Specific Interpretation
The engineering intent is to address Joint Fatigue specifically for the Butterfly Back Occasional Armchair, illustrated here within a calibrated Hotel Lobby context.
This is achieved through the OE-Lock™ Multi-Axis Joinery System, which operates by buffering the internal matrix against the repetitive stress vectors of guests leaning against the split backrest.
As a result, the risk of structural failure at the spine connection is limited under the influence of Cyclic Loading.
Construction & Material Behaviour
For this Butterfly Back Occasional Armchair, the selected Full-Grain Leather is bonded to a core engineered specifically for commercial stability.
- Substrate Stack: Kiln-dried Beech hardwood with integrated metal dowel reinforcement in the central spine.
- Joinery: OE-Lock™ system bridging the vertical spine to the rear seat rail.
- Finish System: Multi-layer lacquer with hand-applied gold leaf, sealed for abrasion resistance.

Frequently Asked Questions
A: No. This documentation defines an engineering framework. Final form, detailing, and tolerances are confirmed during the bespoke specification phase.
Q: Can this be calibrated for high-traffic hospitality environments?
A: Yes. One calibrated scenario involves reinforcing the central spine connection to withstand the cyclic loading common in these settings.
Q: How does the split-back structure perform over time?
A: The internal joinery is calibrated to allow for micro-movement; maintenance intervals for checking joint tightness are defined during the specification phase.
Q: Can dimensions be modified?
A: Yes. All frames are built to order, allowing for millimetre-perfect calibration.
