Use dimensions, not labels
Put the finished length, width and unit of measure on the specification even when a market name such as twin, queen or king is used.
SIZE & DIMENSIONS
Mattress Size Guide for OEM and Wholesale Buyers
Mattress size names are useful for shoppers, but B2B orders should be controlled by actual dimensions, tolerances, construction and packaging requirements.
Mattress size planning starts with exact finished dimensions. Market names such as twin, queen and king are useful for merchandising, but an OEM or wholesale purchase order should also state the controlling length, width, unit of measure, target height and construction.
Size also affects spring layout, foam cutting, quilting panels, cover dimensions, carton labeling and container planning. For compressed products, the measurement method and recovery point should be agreed before production so incoming inspection and customer instructions use the same standard.
Mattress Size Decisions That Affect Production
Separate size from height
Width and length define the footprint; mattress thickness or height is a separate specification that affects construction, carton planning and merchandising.
Account for recovery
For compressed models, final size and height should be checked after the agreed recovery period rather than directly after opening.
Plan the size matrix
Wholesale and project orders should define quantities by size so production, carton labels and loading plans stay aligned.
How to Convert Mattress Size Requirements Into an OEM Brief
| Buyer situation | What to specify | Why it matters | Recommended next step |
|---|---|---|---|
| Retail / wholesale range | Market size name + exact dimensions + height | Prevents ambiguity when size labels differ by country or retailer | Mattress product categories |
| Hotel / project | Bed-base dimensions + room schedule + quantity by size | Connects room types to the correct mattress specification | Applications |
| Custom size OEM | Exact dimensions + tolerance + construction + packaging | Lets the factory judge feasibility before sampling | OEM custom size |
| Roll-pack / e-commerce | Finished size + compressed carton dimensions + recovery check | Links the product specification to logistics and customer instructions | Roll-pack OEM |
How to Write a Mattress Size Specification
Write the finished size as length × width and state the unit. Add the familiar market name only as a secondary reference because size names can vary between countries, retailers and project specifications.
Tie the size to a defined construction platform. A custom dimension can change spring geometry, foam yield, cover patterning, quilting size and packaging, so the factory also needs target quantity and packaging method before confirming feasibility.
How Size, Thickness and Packaging Interact
Mattress footprint and mattress thickness are separate controls. Two products with the same width and length can require very different bills of material when support core, comfort layers and total height change.
For roll-pack programs, include the finished size, target height, compression method, carton format and the agreed point at which final dimensions will be verified after recovery. This prevents a logistics specification from conflicting with the finished-product specification.
Custom Dimensions, Tolerances and Regional Size Names
Custom mattress sizes should be reviewed against the selected spring or foam platform rather than treated as a simple cutting change. A dimensional change may be straightforward for an all-foam model but can require a different coil layout, border design, quilting pattern or cover size in a spring mattress.
Regional names such as Twin, Double, Queen and King should be treated as labels rather than the controlling specification. For export orders, record the exact length, width, unit of measure and agreed tolerance alongside the market name used on packaging or sales materials.
Managing Multi-Size and Multi-Market Programs
For hotels, distributors and private-label programs, maintain a size matrix for every SKU. Include the exact finished dimensions, target height, construction, packaging format, quantity and the size name used in each destination market.
The same matrix can be used to check purchase orders, carton labels, barcodes, room schedules and receiving records. Keeping one controlled size reference reduces errors when a range contains several sizes or is sold in more than one market.
Detailed Technical Reference Data
When you need exact reference values, open the Technical Database for detailed spring, foam, fabric and finished-mattress records that support quotation and specification work.

Frequently Asked Questions
Should a purchase order use mattress size names or actual dimensions?
Use actual dimensions in centimeters or inches as the controlling specification. A name such as twin, queen or king can be added as a market reference.
Can custom mattress sizes be produced?
Yes, but feasibility depends on the requested dimensions, construction, quantity, cover pattern and packaging method. Custom spring units can require more engineering than simple foam cutting.
When should a compressed mattress be measured?
Use the recovery point agreed for the approved construction and packaging method. The same timing should be used for production checks, receiving inspection and customer-facing instructions.
Should mattress height be included in the size specification?
Yes. Height is separate from length and width and should be stated because it affects construction, cover dimensions, carton planning and product positioning.
What should be included in a multi-size wholesale order?
Use a size matrix with exact dimensions, height, construction, quantity, packaging, labels and SKU codes for every size.
