China vs Vietnam Mattress Manufacturing: How Buyers Should Compare Sourcing Options

When sourcing mattresses for the UK market, comparing manufacturing options in China and Vietnam requires a detailed, factory-level assessment rather than relying on broad country reputations or general labour costs. There is no universal "winner" between these two sourcing locations; the best choice depends entirely on your specific mattress programme, quality requirements, and commercial terms. A fair comparison starts by defining the exact mattress construction, required volumes, packaging, and delivery terms to ensure all supplier offers are genuinely comparable.

Start with the mattress programme, not the country

Before comparing countries, define your mattress programme with a single, controlled Request for Quotation (RFQ) brief. This ensures that any quotes received from suppliers in China or Vietnam are based on identical specifications and commercial assumptions, making a like-for-like comparison possible. Without a clear baseline, differences in quoted prices might reflect variations in product specification, packaging, or delivery terms rather than actual manufacturing efficiency or cost advantages.

Build one controlled RFQ brief

To make your comparison auditable and reduce quote ambiguity, your RFQ brief should include the following fields. This checklist helps ensure that both suppliers quote against the same requirements.

• Mattress Construction/BOM Revision: Specify the exact bill of materials, including foam types, spring count/gauge, fabric composition, and any internal components. Include the latest approved revision number.
• Dimensions: Provide precise dimensions (length x width x height) in metric units, along with any acceptable tolerances.
• Quantity: State the annual volume, initial order quantity, and forecast cadence.
• Packaging: Detail inner and outer packaging specifications, including compression, roll-packing, carton dimensions, palletisation, and labelling requirements.
• Inspection Requirements: Outline your quality control points, acceptable quality limits (AQLs), and any third-party inspection mandates.
• Delivery Point and Incoterm: Clearly state the desired Incoterm (e.g., FOB, CIF, DDP) and the final delivery location in the UK.
• Sample Requirements: Specify the number and type of samples needed (e.g., pre-production, golden sample).
• Target Launch Date: Provide your desired market launch timeline.
• Quote Date and Validity: Require suppliers to state the date of their quote and its validity period.
• Currency: Specify the currency for all quoted prices.
• Explicit Exclusions: Ask suppliers to list any items or services explicitly excluded from their quote.

By standardising these elements, you can identify whether two quotes are genuinely comparable or if hidden differences in scope are skewing the price. This approach helps prevent estimates from being mistaken for supplier commitments.

Compare factory capability with factory-level evidence

When evaluating sourcing options, it is crucial to separate national manufacturing context from the specific capabilities and controls of an individual factory. While country-level data can provide background, it does not directly prove a supplier's ability to meet your specific product and quality requirements. Prefer the supplier that can demonstrate repeatable control of the exact construction and volume, regardless of country. This applies when the product specification and order volume are clearly defined, and suppliers can provide current process and quality evidence.

The situation changes if one supplier cannot evidence the required process, material traceability, or capacity, or if sample results or production records show unresolved quality risks. Verification is needed for the current BOM/construction revision and approved sample, process-specific capacity and lead-time assumptions, and inspection criteria, defect/rework history, and corrective-action closure. 

AIYI operates owned manufacturing bases across multiple countries. This multi-country footprint allows us to offer flexible sourcing solutions, potentially mitigating risks associated with single-country dependencies and providing options that align with evolving supply chain strategies for UK importers and retailers.

Use wages and national indicators carefully

National wage and logistics data offer macroeconomic context but should not be used as direct proxies for a specific factory's performance or unit cost. For instance, Vietnam's National Statistics Office reported an average employee income of VND 8.4 million per month in 2025, an 8.9% increase year-on-year, alongside strong manufacturing growth. While this indicates a dynamic labour market, it is a national average and not a direct measure of mattress-factory wages or productivity.

A factory's unit economics are influenced by many factors beyond headline wages, including:

• Productivity: The efficiency of labour and machinery.
• Automation: The level of automated processes reducing manual labour.
• Yield: The percentage of good products produced from raw materials.
• Material Sourcing: The cost and availability of raw materials, which can vary by region and supplier.
• Overhead: Fixed costs like rent, utilities, and administrative expenses.
• Factory Utilisation: How effectively the factory's capacity is being used.

Similarly, the World Bank's 2023 Logistics Performance Index (LPI) assesses a country's ability to move goods across borders, considering logistics services, infrastructure, and border controls. This is a country-level indicator of overall logistics environment, not a guarantee of specific shipment transit times or costs for your particular route.

For example, UK imports under HS 940429 (mattresses fitted with springs or stuffed/internally filled) in 2024 show a much larger recorded flow from China (approximately US$62.25 million, 595,995 items) compared to Vietnam (approximately US$99,760, 955 items). This indicates China's established volume within this product code, but not necessarily superior quality or universal suitability.

The buyer should understand which macro indicators are useful context and which questions require specific supplier evidence.

Ask for comparable quality records

To verify whether production quality is repeatable, turn quality claims into verifiable evidence requests. Ask for records that demonstrate a factory's control over its processes and output.

Request the following:

• Incoming Material Controls: Documentation of checks performed on raw materials upon arrival.
• In-Process Checkpoints: Records of quality inspections at various stages of manufacturing.
• Final Inspection Criteria: The standards and procedures used for inspecting finished products.
• Defect/Rework Trends: Data on common defects, rework rates, and their resolution over time.
• Corrective Action Records: Documentation of how quality issues are addressed and prevented from recurring.

Ensure that these records correspond to the proposed factory, the specific product you are sourcing, and a recent production period. This approach helps you ask for evidence tied to the product and production site rather than relying on generic assurances. AIYI applies incoming-material, in-process, finished-product, and pre-loading quality checks.

Compare total landed cost, not just the factory price

A headline factory price can be misleading if it doesn't account for all costs incurred to get the product to your UK warehouse. A transparent, like-for-like cost model is essential. Compare total cost to the same UK delivery point and specification, with all exclusions made visible. This applies when both suppliers quote against the same controlled RFQ, and packing and shipping assumptions are documented.

The situation changes if freight quotes cover different dates, ports, container utilisation, or service levels, or if one quote excludes duties, destination charges, inspection, or required packaging. Verification is needed for dated freight and inland transport quotations, measured packed dimensions and a realistic load plan, and the current commodity code and applicable duty treatment.

Separate quoted costs from assumptions

To prevent estimates from being mistaken for supplier commitments, create a detailed landed cost breakdown. Label each line item clearly to distinguish between confirmed figures and placeholders that require further verification.

Keep the date, currency, unit basis, and any explicit exclusions beside each figure. This allows you to distinguish evidence-backed costs from placeholders that need follow-up. UK government guidance states that commodity codes determine customs duty and import VAT treatment, and that relevant preferential tariff rates depend on meeting the applicable rules of origin. The UK-Vietnam trade guidance also notes that preferential tariff treatment requires the product to meet the relevant agreement's rules of origin, and commodity-code definitions beyond the first six HS digits can differ by importing country and may change.

Check shipping, origin rules and UK product requirements

Integrating route-specific delivery risk, rules of origin, commodity classification, and UK product-safety scope into your decision is critical. Do not include assumed tariff savings or transit-time advantages in the business case until the exact SKU, origin, and route are verified.

This applies when the product and manufacturing route are known, and the importer can obtain current customs and carrier information. The situation changes if the BOM or manufacturing process affects origin determination or commodity classification, or if the product falls under a changed or specially scoped safety provision.

Verification is needed for the current UK commodity code and tariff rate, rules-of-origin eligibility and supporting documentation, current carrier schedule and full port-to-door cost, and applicable product-safety/fire-safety requirements for the destination territory.

Verify origin before assuming a tariff advantage

It is a common misconception that dispatching goods from Vietnam automatically qualifies them for preferential tariffs into the UK. This is not always the case. You must distinguish between the country of origin and the country of dispatch.

• Country of Origin: HMRC defines this as where goods were produced or manufactured, or where they underwent the last substantial transformation. This is the critical factor for determining tariff treatment.
• Country of Dispatch: This reflects the country of the last commercial transaction and may differ from where the goods were made or shipped.

To qualify for preferential tariff treatment under trade agreements (such as the UK-Vietnam Free Trade Agreement), your mattress must meet specific rules of origin for its commodity code. These rules often require a certain percentage of value-add within the originating country or specific manufacturing processes to be completed there.

Before pricing in any preferential tariff advantage, you must:

• Confirm the correct UK commodity code (HS code) for your exact mattress construction.
• Verify the agreement-specific origin rule that applies to that commodity code.
• Obtain supporting documentation from your supplier that proves the mattress meets these origin rules.

This process requires confirmation from your customs broker or importer. Without this verification, assuming a tariff advantage could lead to unexpected duty costs. UK government guidance states that commodity codes determine customs duty and import VAT treatment, and that relevant preferential tariff rates depend on meeting the applicable rules of origin. The UK-Vietnam trade guidance also notes that preferential tariff treatment requires the product to meet the relevant agreement's rules of origin, and commodity-code definitions beyond the first six HS digits can differ by importing country and may change.

Additionally, remember that UK government guidance on the 2025 furniture and furnishings fire-safety amendments states that products removed from the amended regulations' scope still need to meet applicable general product-safety requirements, and that relevant standards may be used to demonstrate fire safety depending on product type. The applicability depends on product type, market territory, and the relevant commencement/scope provisions.

Make the decision with a documented supplier scorecard

To make a defensible sourcing decision, convert all the gathered evidence into a practical go/no-go decision using a documented supplier scorecard. Choose the supplier-location combination that passes mandatory requirements and has the strongest evidenced total cost, process fit, and delivery-risk profile.

This applies when both offers are based on the same product and commercial scope, and critical compliance and quality evidence has been reviewed. The situation changes if one supplier fails a mandatory technical, compliance, or capacity requirement, if the landed-cost difference is smaller than the uncertainty or risk allowance, or if a single-source dependency creates unacceptable continuity risk.

Verification is needed for a signed-off RFQ comparison and landed-cost model, approved sample/BOM and current quality records, confirmed capacity and dated production/shipping schedule, origin, tariff and product-safety review, and a named owner for each unresolved issue and date for closure.

Score each supplier against the same criteria, separating mandatory pass/fail requirements from weighted preferences. Record the evidence date, owner, unresolved assumptions, and a revalidation date for fast-changing items like freight rates or compliance rules. The best location is the one that meets your specific constraints with the strongest verified total proposition, not necessarily the one with the lowest headline wage or quote.

In short, the best sourcing choice for your mattress programme cannot be determined by country labels alone. It requires a controlled specification, comparable landed-cost quotes, factory-level proof of capability and quality, and current UK customs and product compliance checks.
