Safer Cots and Nursery Furniture: What Lullaby Trust and British Standards Require

Choosing a cot is one of the bigger purchases new parents make, and it’s also one where safety standards matter more than aesthetics or brand reputation. Guidance from the Lullaby Trust, the UK charity dedicated to safer baby sleep, sets out clearly what a safe sleep space actually requires — and where common nursery products fall short.

The safe sleep space essentials

According to Lullaby Trust guidance, a safe cot setup centres on a few core elements: a firm, flat, waterproof mattress that fits the cot properly, in a clear sleep space free from loose items. Bedding should either be sheets and blankets tucked in no higher than shoulder height, or a baby sleep bag appropriately sized and tog-rated for the room temperature. A room thermometer is recommended to help parents monitor and maintain a comfortable sleeping temperature, since overheating is a recognised risk factor in unsafe sleep.

Products to avoid — even popular ones

This is where Lullaby Trust guidance becomes particularly pointed. The charity specifically warns against a number of widely sold nursery products, including cot bumpers, sleep positioners, baby nest-style pods, and furry or fluffy blankets. These products contradict evidence-based safer sleep guidance and may increase the risk of Sudden Infant Death Syndrome (SIDS), despite often being marketed as comfort or safety items.

Pillows, soft bulky bedding and duvets present a related hazard for babies under 12 months, according to Lullaby Trust guidance, since they can pose a risk of overheating and may obstruct a baby’s airway. None of these items should be used in a cot for a baby under one, regardless of how they’re marketed.

The gift problem

One of the more striking findings from Lullaby Trust research is how many of these unsafe products reach families as well-meaning gifts rather than deliberate purchases. Their survey found that 41% of parents had received potentially unsafe sleep products as gifts — meaning even parents who’ve done their own research on safer sleep can end up with risky items in the house from relatives or friends unaware of current guidance.

It’s worth being direct with family and friends ahead of a baby shower or birth about what’s genuinely useful versus what current safety guidance actually recommends avoiding, rather than assuming good intentions guarantee a safe product.

Don’t assume popularity equals safety

Lullaby Trust guidance makes a point that’s easy to overlook when browsing online: positive reviews from other consumers do not mean a product meets basic safety tests. A product can be widely bought, highly rated and still fall short of recognised safety standards, particularly for newer nursery product categories that haven’t been around long enough to be covered by well-established British Standards.

The British Standards that actually apply

The relevant standards are specific and named. Cots and folding cots for domestic use, with an internal length between 900mm and 1,400mm, must meet BS EN 716-1, which sets safety requirements covering slat spacing, the maximum gap between mattress and cot side, locking mechanisms on folding and convertible cots, and warning labelling — with BS EN 716-2 setting out the test methods used to check compliance. Cot mattresses are covered separately by BS EN 16890, which sets safety and test requirements for mattresses, bases and toppers used in cots, travel cots and cribs, including flammability, materials and dimensional fit. Both are published by the British Standards Institution (BSI) and sit underneath the UK’s general product safety law, enforced by the Office for Product Safety and Standards (OPSS) and local Trading Standards.

It’s worth being clear about the difference between a legal product standard and charity guidance. BS EN 716 and BS EN 16890 are the formal standards a cot and cot mattress are expected to meet before sale. The Lullaby Trust’s safer-sleep advice — on bedding, room temperature and which products to avoid — is separate: it’s evidence-based good-practice guidance about how a cot is used, not a product manufacturing standard. A cot can meet BS EN 716 and still be set up in a way the Lullaby Trust advises against, so the two types of guidance need checking independently rather than treated as the same thing.

How to check what you’re buying

Practical verification steps recommended by the Lullaby Trust include:

• Confirm the product complies with relevant British Standards — this should be stated clearly on the packaging or the retailer’s product page. For a cot, that’s BS EN 716-1; for a cot mattress, it’s BS EN 16890.
• Don’t rely on brand recognition alone as a guarantee of safety; well-known brands aren’t immune from selling non-compliant products.
• Check second-hand cots and nursery items particularly carefully, since safety standards and recall notices can predate the item’s manufacture, and wear over time can compromise structural safety.
• If in doubt about a specific product, the Lullaby Trust’s helpline can offer guidance.

This isn’t a complete checklist of every safety consideration for every nursery product on the market, and standards can be updated over time — checking current guidance before a purchase is more reliable than working from memory of what was recommended a few years ago.

Getting support

The Lullaby Trust runs a helpline (0808 802 6869, staffed 10am–2pm on weekdays) for parents who want to talk through specific safer sleep questions, including product choices, with someone knowledgeable rather than relying solely on online research.

Setting up the nursery before the baby arrives

Many parents set up a nursery and buy cot-related items well before the birth, often as gifts are received or during a “nesting” phase of preparation. This is a sensible time to apply the checks above methodically, rather than trying to audit an entire nursery’s worth of items in the sleep-deprived early weeks after birth. Going through each item — the cot itself, the mattress, and any bedding — and confirming British Standards compliance before the baby’s first night in the space is far more manageable done in advance.

It’s also worth thinking specifically about second-hand or hand-me-down cots, which are extremely common given how expensive nursery furniture can be. A cot that was perfectly safe for an older sibling or a friend’s baby some years ago may predate updates to safety standards, or may have sustained wear that isn’t obvious without close inspection — loose or missing parts, degraded slats, or a mattress that’s lost its firmness over time. None of this means second-hand cots should be avoided altogether, but it does mean the same verification checks matter just as much, if not more, for a second-hand item as for something bought new.
