Hospital Bed Mattress Sizes and Fit: Avoid the Gap
A mattress that is too small leaves gaps; too large will buckle. Measure the bed deck and rails, and confirm the mattress flexes with profiling beds.
Key points
- Measure the deck. Measure inside length and width between rails and the head and foot boards, and note the maximum mattress thickness allowed by the rails.
- Common variants. Adult, paediatric, bariatric and narrow beds all use different sizes.
- Confirm before bulk. Send the bed model and approve a sample on the actual bed before the bulk order.
- Why fit problems cost money. A mattress that is a little too narrow leaves a gap where a patient limb or a sheet can catch.
- Detailed guidance. Fit begins with measuring the bed deck inside the rails, at the head, middle and foot, and the clear height from deck to the top of the rail.
Measure the deck
Measure inside length and width between rails and the head and foot boards, and note the maximum mattress thickness allowed by the rails.
Common variants
Adult, paediatric, bariatric and narrow beds all use different sizes. Profiling beds need a flexible core.
Confirm before bulk
Send the bed model and approve a sample on the actual bed before the bulk order.
Fit checklist
Measure the deck at head and foot, between the rails, and the depth from deck to rail top. Allow only a small tolerance on width. Confirm whether the bed bends at the knee and head sections, and approve a sample on the real bed before the bulk order.
Measurement sheet
| Measure | Where | Note |
|---|---|---|
| Deck length | Head to foot inside the frame | Allow tolerance |
| Deck width | Between side rails | Check at head and foot |
| Rail height above deck | Deck to top of rail | Sets maximum thickness |
| Bend points | Knee and head sections | Flexibility needed |
Why fit problems cost money
A mattress that is a little too narrow leaves a gap where a patient limb or a sheet can catch. One that is too long buckles at the foot end and wears the cover. Across hundreds of beds, small errors multiply into complaints and returns. Measuring a sample bed in the actual ward, not from a brochure, is the cheapest way to avoid this.
Detailed guidance
Fit begins with measuring the bed deck inside the rails, at the head, middle and foot, and the clear height from deck to the top of the rail. Note whether the deck is split into sections that move and where the bend points fall. Then check how the mattress behaves when the deck articulates: it should flex without creasing, cracking or riding up.
If you have several bed models, group them by deck size and choose a small number of mattress sizes, which simplifies stock and replacement. Paediatric and bariatric beds need their own sizes and constructions. Order a sample for each size and test it on the real bed through its full range of positions before placing the bulk order. Record the approved dimensions with tolerance in the contract.
Worked example (illustrative figures)
A ward's beds measure 2000 mm by 900 mm between rails. A catalogue mattress is 1980 by 880. The gap lets sheets and limbs catch and the cover rides up. A mattress built to 1995 by 895 fits snugly and flexes at the knee break. Measuring the real bed, not the brochure, avoided repeating the error across 80 beds.
