2D vs 4D massage chair: write the decision into your order brief.
Compare the same quotation scope, with required behavior, acceptable alternatives and buyer approval kept explicit.
Write “required”, “preferred” or “supplier to clarify”.
Start with the purchasing scope rather than treating 2D or 4D as a complete specification. Ask how the exact model varies movement, depth, speed and intensity, and request its manual and demonstration scope. A feature label describes a question, not verified behavior. Keep unknown values visible: a supplier can answer an open question but cannot identify an unstated constraint.
Use catalog configurations to describe the inquiry option without implying inventory. The buyer decides which controls, finish and service conditions are mandatory and who may approve alternatives.
- Product and specification. List mechanism alternatives separately. Record floor area and access route; request upright/reclined dimensions in inches, user-fit range in lb and clearance requirements.
- Quantity and US destination. Give pieces per configuration, color split and sample quantity. Ask for MOQ, included controller, accessories, pack contents and carton count.
- Packaging, documents and timing. Specify receiving date, assembly need and exact-model files. Request V, W, plug, dated dispatch assumptions, freight boundary and installation exclusions.
Compare the same scope before choosing an alternative.
Available for comparison
Record supplied specifications and quotation revisions on one basis. Write the optional budget amount or range, currency and whether it applies per chair or to the whole order. Define samples, freight, duties, destination handling and assembly inclusions. A factory figure may cover less than the receiving-site requirement; show exclusions beside the price.
A high-end preference can invite added controls, finish or parts support; a budget preference can invite a simpler configuration. Ask candidates to identify and price changes separately. Merchant preference is not a verified supplier rating, and an existing quotation is not needed to state a target.
Confirm per quoted model
- Specification and packing. Bind sample and quoted chair to one identifier and revision. Follow the instructions to compare controls, dimensions, accessories and pack contents; record conditions and open points.
- Documents and delivery responsibility. Request the manual, label images and relevant exact-model reports, identifying issuer and scope. Assign electrical, claims or market questions to the qualified reviewer; identify who arranges assembly.
- Unresolved decisions. A sample does not establish lifecycle performance, a related-series document does not approve the offered chair, and a requested date is not a commitment until confirmed. The buyer signs off configuration, evidence and commercial terms.
Our independent sourcing service coordinates candidate questions using your product specifications, pieces, destination, timing and document needs. Supplier information is checked against the specific reply, not assumed from a catalog; you retain final approval. The procurement article provides further questions to carry into your brief.
