The chair will physically accommodate users outside these ranges, but the body scan and SL-Track geometry are calibrated for the listed range, which is where the massage feels best.\"}}, {\"@type\": \"Question\", \"name\": \"How much wall clearance does it need?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This chair is engineered for compact spaces — typical wall clearance is around 5\\\" (verify) from the back of the chair to the wall in upright position. The chair slides forward as it reclines, so once installed it doesn't need significant rear clearance for full recline.\"}}, {\"@type\": \"Question\", \"name\": \"How does the voice control work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Built-in voice recognition responds to direct commands — start, pause, switch program, adjust intensity. It's not a smart-home integration; it's a chair-only control system that works without WiFi or phone pairing.\"}}, {\"@type\": \"Question\", \"name\": \"What does delivery look like?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Standard delivery is curbside (driver leaves the crate at your driveway\/garage) and is included in the listed price. White-glove (in-room placement, unboxing, debris removal) is available as a paid upgrade — typically $250-450 depending on access. Lead times are 5-12 business days from order, and we send tracking the moment the supplier provides it.\"}}, {\"@type\": \"Question\", \"name\": \"Can I finance it?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes — Shop Pay Installments at checkout splits orders up to $4,000 into 4 interest-free payments, and orders above that into 6-12 monthly payments with interest disclosed at checkout. At $5,999, this chair fits the longer-term plan; the exact monthly figure shows up the moment you select Shop Pay at checkout.\"}}, {\"@type\": \"Question\", \"name\": \"What's covered by the warranty?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Standard 1-year parts and labor warranty from the manufacturer is included. 2-year and 3-year extensions are available as paid upgrades and are sold through the supplier — we handle the paperwork on your behalf and forward you the warranty document. We also include shipping insurance on every order.\"}}, {\"@type\": \"Question\", \"name\": \"What's the return policy?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"30-day return window if the chair is unopened (factory-sealed crate). Once unboxed, returns are evaluated case-by-case — most issues are resolved by warranty replacement of the affected part rather than full chair return, since these chairs ship in a single multi-hundred-pound crate.\"}}]}\u003c\/script\u003e\n","brand":"Osaki","offers":[{"title":"Beige \/ White Glove - $275 \/ 5 Year(3 Years Full Service \u0026 Additional 2 Years Parts)","offer_id":47065799098553,"sku":"osaki-4d-bravo-duo-mech-1","price":6274.0,"currency_code":"USD","in_stock":true},{"title":"Brown \/ White Glove - $275 \/ 5 Year(3 Years Full Service \u0026 Additional 2 Years Parts)","offer_id":47065799164089,"sku":"osaki-4d-bravo-duo-mech-3","price":6274.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ White Glove - $275 \/ 5 Year(3 Years Full Service \u0026 Additional 2 Years Parts)","offer_id":47065799229625,"sku":"osaki-4d-bravo-duo-mech-5","price":6274.0,"currency_code":"USD","in_stock":true},{"title":"Blue \/ White Glove - $275 \/ 5 Year(3 Years Full Service \u0026 Additional 2 Years Parts)","offer_id":47065799295161,"sku":"osaki-4d-bravo-duo-mech-7","price":6274.0,"currency_code":"USD","in_stock":true},{"title":"Beige \/ Curbside - Free \/ 5 Year(3 Years Full Service \u0026 Additional 2 Years Parts)","offer_id":47065799360697,"sku":"osaki-4d-bravo-duo-mech-0","price":5999.0,"currency_code":"USD","in_stock":true},{"title":"Brown \/ Curbside - Free \/ 5 Year(3 Years Full Service \u0026 Additional 2 Years Parts)","offer_id":47065799426233,"sku":"osaki-4d-bravo-duo-mech-2","price":5999.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ Curbside - Free \/ 5 Year(3 Years Full Service \u0026 Additional 2 Years Parts)","offer_id":47065799459001,"sku":"osaki-4d-bravo-duo-mech-4","price":5999.0,"currency_code":"USD","in_stock":true},{"title":"Blue \/ Curbside - Free \/ 5 Year(3 Years Full Service \u0026 Additional 2 Years Parts)","offer_id":47065799524537,"sku":"osaki-4d-bravo-duo-mech-6","price":5999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/3830\/4185\/files\/osaki-4d-bravo-duo-beige-6353893.png?v=1777437589"},{"product_id":"osaki-4d-3d-manhattan-duo-free-2yrs-warranty-massage-chair","title":"Osaki 4D + 3D Manhattan Duo Massage Chair – SL Massage Chair","description":"\u003c!-- pff:pdp-fix v2 --\u003e\n\u003cp class=\"pff-lead\"\u003eThe \u003cstrong\u003eOsaki 4D + 3D Manhattan Duo – SL\u003c\/strong\u003e is a premium 4D+3D Dual performer at this price band — typically more spec-for-the-money than chairs $1-2K above it.
