Bed Size & Mattress Compatibility Guide

A bed frame and mattress must be specified as one system. Confirm the destination market, sleeping size and internal frame dimensions before quotation, sampling and packaging approval.

INTERNAL WIDTH × LENGTH

Replace with an approved bed-frame dimension drawing showing internal mattress space, overall footprint and headboard height.

01 · Start with market

UK, EU, North American and other size names are not interchangeable.

02 · Verify dimensions

Use millimetres for the internal mattress space and overall product footprint.

03 · Approve as a system

Bed frame, slat system, mattress height and packaging must be reviewed together.

What buyers must confirm

Size name alone is not enough.

Retail size labels vary by country and sometimes by retailer. Quotations should therefore reference both the market name and exact mattress dimensions.

Mattress size

Nominal width × length in millimetres, plus acceptable production tolerance.

Internal bed space

Clear space inside the side rails and between headboard and footboard.

Overall footprint

Maximum external width, length and height for product pages and room planning.

Mattress height

Affects the visible headboard, side-rail relationship and storage-bed operation.

Reference framework

Common market conventions

MarketTypical namingWhat to put on the RFQ
United KingdomDouble, King, Super KingName + exact mattress dimensions in mm
European Union140×200, 160×200, 180×200Width × length and local tolerance expectation
North AmericaFull, Queen, KingNamed size + exact inch/mm specification

These examples are orientation only, not final manufacturing specifications. Retailer standards and destination-market requirements must be confirmed for each programme.

Compatibility checkpoints

Review before sampling

  • Slat spacing and centre-support arrangement
  • Mattress retention and clearance around upholstery
  • Gas-lift force matched to mattress weight
  • Finished mattress height against the headboard design
  • Carton dimensions, access routes and container plan
