Diy wooden stool online retail in korea

TAM TOP-DOWN

Start with the global e-commerce furniture market. Two sources diverge sharply: ResearchAndMarkets pegs it at $37.4B in 2025; IntelMarketResearch at $101.1B. The $101.1B figure appears to include marketplace gross merchandise value, so use it as the ceiling. Apply the wood segment share of 55% (Straits Research) to get the wood online furniture market, then apply the residential segment share of 68% to isolate the home consumer target. Result is the honest TAM scope for a residential online wood furniture retailer.

$101.1B x 0.55 wood share x 0.68 residential share = $37.8B; use $38B; narrowed to stool-adjacent category not computed here, computed in SAM

TAM BOTTOM-UP

Approximately 1.9 billion global households. Apply 45% furniture-buying rate (U.S. Proxy, Gitnux) to get 855M buyers. Apply 20% e-commerce penetration (industry research) to yield 171M online furniture buyers globally. Assume 15% purchase wood-specific items and 10% of those buy stools or stool-adjacent seating in a given year, giving 2.6M stool buyers. At a $120 blended ASP the implied TAM is $310M. This is far below the top-down $38B, confirming the top-down is the right frame for the full category TAM, not this product.

1.9B households x 0.45 x 0.20 x 0.15 wood x 0.10 stools x $120 ASP = $307M bottom-up product TAM

SAM FILTERS

From the $38B top-down residential online wood furniture TAM, apply three filters. First, stool-specific share: stools are a narrow seating sub-category; assume 2% of wood residential online furniture spend, yielding $760M. Second, DIY or assembly-required share: IKEA and RTA-style formats hold roughly 30% of the stool market by unit volume; apply 30% to get $228M. Third, addressable geography and channel reach for a Korea-based new entrant without omnichannel scale: apply a 50% reachability haircut, yielding $114M, rounded to $110M SAM.

$38B x 0.02 stool share x 0.30 DIY share x 0.50 reach haircut = $114M, display $110M

SOM BUILD

A competent new entrant in year 1 targets 0.5% of $110M SAM, or $550K, roughly 4,600 units at $120 ASP. Year 2 doubles via repeat buyers and SEO maturity to $1.1M. Year 3 reaches 2% SAM share at $2.2M, roughly 18,300 units annually. This assumes no major retail partnership, 30% return rate absorbed into net revenue, and customer acquisition cost of $25 to $40 per order limiting margin. Three-year cumulative revenue approximately $3.85M. The 2% ceiling reflects Amazon's 35% U.S. Share and IKEA's pricing dominance leaving little room.

18,300 units x $120 ASP x (1 - 0.30 return rate net adjustment of 0.85 after restocking) = ~$1.87M net; gross SOM stated at $2.2M pre-return-cost
