A 10-year wall bed reduces furniture turnover compared to lower-cost alternatives that fail at year 2–3. That's the structural sustainability argument. But "structural" isn't "measured." Below is what we can defensibly claim, what we can't yet, and the methodology we'll use to fill the gap.
1. What we can claim today
The SBLM mechanism is rated for daily deploy/stow cycles for the 10-year warranty period. Many installs we've serviced from before 2018 are still running their original mechanism — empirical evidence (not yet audited) that real-world life often extends past the warranty.
Every component (mechanism, hinge, drawer runner, latch, panel) can be replaced individually. The whole bed never has to come out for a single-component failure. Compare with sofa-beds whose internal mechanisms typically aren't user-serviceable.
When a customer sells the flat, the warranty transfers free to the new owner. Most installs stay in the flat across ownership changes — we observe this on follow-up calls. This avoids the "remove + scrap" path that hits sofa beds when an owner moves.
Egger and Kronospan E0 panels meet CARB Phase 2 + EPA TSCA Title VI for formaldehyde emissions. The certificate is on the manufacturer datasheet — see /materials-provenance.html.
We don't bundle (and don't mark up) mattresses. Customer reuses an existing one, buys local, or buys online — the choice that's lowest-freight and lowest-cost is usually the customer's existing mattress.
2. What we don't yet have measured
Three claims that would be greenwashing if we made them today.
We have not done a Life-Cycle Assessment (LCA) of a typical install. Components ship from at least 4 countries. The honest number requires manufacturer LCA data + freight emissions + install-day emissions. We're researching a HK-based LCA consultant to commission this for the 2027 report.
This is the kind of figure other furniture sellers cite without methodology. We don't have the methodology. The argument that a 20-year wall bed avoids ~7 sofa-bed replacements has structural logic but isn't an audited number — and we'll only publish a number when we can show the calculation.
If a customer eventually scraps a wall bed (rare but possible), the panels go to landfill, the steel can be recycled, the hardware is mixed waste. We have not measured the recycling rate. We're committed to publishing one once we've removed enough to have a real sample.
3. 2027 audit roadmap
- Commission a HK-based LCA covering a typical single-bed install. Publish the methodology + the per-install kg-CO₂e number.
- Document the waste-stream for the next 3 customer-requested wall bed removals (with consent). Measure recycling fraction by mass.
- Track delivery freight per install (km, vehicle type) starting Q3 2026. Publish median + range in the 2027 transparency report.
- Compare apples to apples: commission an independent comparison of our 10-year wall bed lifecycle vs typical HK sofa-bed turnover, using the LCA above.
Why we publish this
Furniture sustainability claims are often the easiest place to greenwash. We'd rather say "we don't have the number yet" than publish a feel-good figure with no methodology. Sustainability is downstream of our actual product strategy — long-life, repairable, transferable. The carbon math will follow once we've measured it.
