UK Safety Standards for Second-Hand Cots
Buying a second-hand cot or cot bed can be a smart way to kit out the nursery. The key is knowing exactly what to check so your little one stays safe. This guide walks you through the main safety points UK parents should consider when sourcing pre-loved cots.
Why second-hand cots need extra attention
Older cots may have been made before current safety rules came into force. Wear and tear, previous repairs or missing parts can create hidden risks. A quick once-over helps you spot anything that could compromise safety before you bring it home.
Check for product recalls first
Before you view any second-hand cot, search the manufacturer’s name and model on the UK government product recalls list. Some popular older models have been recalled because of faulty dropsides or gaps that pose entrapment hazards. If the seller cannot tell you the exact make and model, it is safer to walk away.
Even if the cot looks perfect, a recall means it no longer meets today’s standards. Always confirm the item is not on any current or past recall list before handing over cash.
Look closely at gaps and bar spacing
UK safety guidance states that the gap between cot bars must be no more than 65mm to prevent a baby’s head from becoming trapped. Run a standard soft-drink can between the bars; if it passes through easily, the spacing is too wide.
Also check the distance between the mattress and the sides. There should be no more than the width of two fingers all the way round. Larger gaps can allow a baby to slip down and become trapped. Pay special attention to the corners and any decorative cut-outs that might create extra spaces.
Common gap problems in older cots
- Worn or missing slats that leave bigger openings
- Loose end panels with decorative shapes
- Drop-side mechanisms that no longer sit flush
Assess stability and overall structure
Give the cot a firm shake. It should feel solid with no wobbling or creaking. Check all joints, screws and fixings. Any signs of woodworm, deep cracks or previous makeshift repairs mean the cot is best left behind.
Make sure the base can be set at different heights as your baby grows. The highest setting is useful for newborns, while the lowest position prevents an older baby from climbing out. If the base does not lock securely into place at each height, choose a different cot.
For families planning ahead, many parents later convert a cot bed into a toddler bed. A stable frame makes this transition smoother. If you are thinking about the next stage, take a look at our range of fun toddler beds for inspiration.
Mattress fit is critical
A cot is only as safe as the mattress that goes inside it. The mattress must fit snugly with no gaps larger than two fingers around the edges. A loose mattress can shift and create dangerous spaces where a baby might become trapped.
Never use a second-hand mattress. Even if it looks clean, it may contain dust mites, mould or have lost its supportive qualities. Instead, pair your pre-loved cot with a brand-new mattress designed for the correct size.
Our cot beds collection includes models that grow with your child. For older toddlers moving on from a cot, a supportive mattress makes the switch to a single bed more comfortable.
Additional safety features to examine
Look for a cot that meets the current British Standard. While not every seller will have the original paperwork, many modern second-hand cots still carry a small label or stamp showing compliance.
Check that any moving parts, such as adjustable bases or drop sides (if still legal on older models), operate smoothly and lock securely. Painted cots should have non-toxic finishes; avoid anything with peeling paint that a baby could chew.
If the cot has been stored in a garage or damp area, inspect for signs of mould or mildew. These can affect air quality in the nursery. A thorough clean with a baby-safe product is always wise, but it cannot fix deep-seated damage.
When to choose new instead
Sometimes the safest option is a brand-new cot. Our kids furniture range includes nursery pieces built to the latest UK and European standards. If you are furnishing a whole room, combining a new cot with coordinating chests of drawers creates a practical, safe space.
For parents who love a themed look, explore our themed kids bedrooms to see how a safe cot can sit happily alongside fun decor that will last well beyond the baby years.
Final checklist before you buy
- Confirm the make and model is not recalled
- Measure bar spacing and mattress gaps
- Shake the frame to test stability
- Check all fixings and moving parts
- Buy a brand-new, correctly sized mattress
- Ask about the cot’s history and previous use
