What makes a metal bed different
Mattress sizes, assembly from the carton, slat gaps and centre legs apply to every bed and are on the beds page. Weld quality, coating thickness and rust apply to all steel and are on the metal furniture page. A steel bed puts both together in a particular way.
Most metal beds from India have tube headboard and footboard frames, often bent into curves, with angle-iron side rails. The rails join the ends with hook-in brackets: a plate with hooks welded to each rail end, dropping into a slotted plate welded to the post. The whole weight of the sleepers passes through four short welds on each side. Other designs bolt the rails on, or use a tube spigot that slides into a socket.
The mattress base is one of three types: wooden slats in plastic clips or caps fixed to the rail, wooden slats resting on the angle, or steel cross bars welded in. Each has its own failure. And because steel does not give, any looseness between two steel parts becomes a squeak or a knock every time someone turns over.
What we check on metal beds
| Check | How it is checked | What fails |
|---|---|---|
| Bracket welds | Weld of every hook plate and slot plate looked at all round; plate thickness measured; bed assembled and loaded by hand at each corner | Weld on one side only, cracked or porous weld, thin or bent plate |
| Joint fit and noise | Hooks dropped into slots; play felt by hand; inspector sits and rolls on the assembled bed | Rails that rattle in the slots, squeak or knock at a joint |
| Anti-squeak parts | Nylon washers, plastic sleeves or felt strips counted against the drawing | Missing or not fitted at steel-to-steel contacts |
| Slat clips and holders | Clips pulled by hand; rivets or screws checked; slats seated and locked | Clips that pop off, cracked plastic, slats that lift out |
| Welded cross bars | Each bar's welds at both ends; bar spacing measured | Bars tacked at one end, spacing wider than specified |
| Bent tube | Outside of every bend checked for cracks and flattening | Cracked or wrinkled bend, tube flattened at the curve |
| Coating at slots and ends | Slots and hooks checked after one assembly; tube tops and finials checked | Coating scraped to bare steel by assembly, open tube tops, finials loose |
Each sampled bed is assembled and taken apart once, because coating damage at the slots only shows after the hooks have been used.
Common metal bed defects and how they are classed
| Defect | Class |
|---|---|
| Cracked or one-sided weld on a rail bracket | Critical |
| Crack at a bend in a headboard tube | Critical |
| Hook bracket edge sharp at shin height | Major |
| Joint squeaks or knocks when used | Major |
| Slat clips detach under hand pressure | Major |
| Anti-squeak washers or sleeves missing | Major |
| Coating scraped to bare steel at slots after one assembly | Major |
| Finial loose but present | Minor |
| Small coating run on the inside of a rail | Minor |
A bracket weld that fails lets a rail drop with someone on the bed, so we class it critical by default. Your specification can set other classes.
Market rules that apply
- US, coatings. Paint on consumer furniture must not exceed 90 ppm lead under 16 CFR 1303. A metal bed sold for children under 12 is a children's product: 100 ppm total lead in accessible parts, third-party testing and a Children's Product Certificate. See CPSIA children's products. Metal bunk beds for children also fall under 16 CFR 1513.
- EU. EN 1725:2023 covers adult beds; EN 747-1 covers bunk and high beds. Both are voluntary, but buyers often ask for them. Coatings fall under REACH.
- Wood slats. Wooden slats bring the timber rules: Lacey Act for the US and, depending on the customs code, the EUDR.
- California. Coatings may need a Prop 65 warning.
Strength, durability and chemical tests are lab work. We pull and seal samples and check the report against the bed and colour shipped.
Packing, transit and loading risks
- Hook plates. Hooks welded to rail ends stick out. They tear cartons and scratch the headboard if packed together. Each hook end needs a card or foam cap.
- Curved headboards. Bent tube frames are springy and can be pushed out of shape by stacking. A rigid board on each face and corner posts in the carton help.
- Slat clips in transit. Plastic clips fitted to rails break off if rails are bundled together. Ask for clips in a bag, or rails separated by foam.
- Hardware bag. Bolts, washers and anti-squeak parts go in one labelled bag, fixed in the carton the instructions name.
What to put in your purchase order
- Bracket type, plate thickness and that bracket welds go all round.
- Anti-squeak parts at every steel contact: nylon washers, sleeves or felt.
- Slat system: clip type and fixing, or cross bar size, count and spacing.
- Minimum bend radius for curved tubes, and that bends are checked for cracks before coating.
- Coating colour, gloss and thickness, with extra cover at slots and hooks.
- Caps on all tube ends and how finials are fixed.
- Whether the bed is marketed for children, so the right tests are planned.
