Cinderella-Fit Search

Related-Item Chains

Every product links to 3-5 related items: required accessories (HEPA filters for air purifiers), protection materials (floor mats for heavy shelves), consumables (vacuum bags), compatible storage boxes.

Curated Sets

• Bundles: "New Life Starter Kit", "Work From Home Set"
• Room Presets: IKEA-style complete room configurations
• Influencer Picks: Real recommendations from YouTubers and magazines
• Hack Sets: Budget alternatives (100-yen substitutes for 1000-yen accessories)

Dimension-Compatible Replacement

• DB-registered successors
• Dimension-compatible alternatives with fit_score (0-100)
• Live Rakuten search results
