How to Choose a Crib

Choosing a crib is one of those decisions that feels bigger than it should, mostly because your baby will spend so many hours in it, night after night, for months or years. Get it right and you’ve got a safe, comfortable spot for sleep and rest. Get it wrong and you’re either dealing with a safety worry or a piece of furniture your toddler has outgrown within a year. This guide walks through what actually matters, not just what looks nice in a nursery photo.

Why the Right Crib Matters

A crib isn’t just a bed. It’s the place your baby will sleep unsupervised for long stretches, often from a few weeks old right through to toddlerhood. That means safety features aren’t optional extras, they’re the whole point. Comfort and looks matter too, but they come second to whether the crib is genuinely safe for your baby to be left alone in.

If you’re ever unsure about safe sleep setup, bedding, room temperature or sleeping position, your midwife, health visitor or GP is a much better source than a product description or a forum post.

Safety: What to Actually Check

This is the part worth spending real time on. A crib that looks beautiful but has wide slats or a wobbly frame isn’t a bargain at any price.

• Slat spacing. Gaps between the bars should be narrow enough that your baby’s head or body can’t get trapped between them. In the UK and EU, cribs sold new must meet BS EN 716, which sets slat gaps at no more than 6.5cm. In the US, the standard (16 CFR 1219) limits gaps to 2 3/8 inches. If you’re buying secondhand or from abroad, measure this yourself.
• Certification marks. Look for compliance with BS EN 716 (UK/EU) or, in the US, check that the crib meets current CPSC standards and carries a JPMA certification seal. These aren’t just stickers, they mean the crib has been independently tested.
• No drop sides. Drop-side cribs (where one side slides down) have been banned in both the US and UK for years because the mechanism can fail and create a gap a baby can slip into. If you’re offered a secondhand drop-side crib, don’t use it, no matter how good the price.
• Mattress fit. There should be no more than about two finger-widths of gap between the mattress and the crib sides. A loose-fitting mattress creates a gap where a baby can become trapped.
• Sturdy construction. Give the frame a firm shake once it’s assembled. It shouldn’t wobble, rock, or creak. Check for smooth edges, no splinters, no small parts that could come loose (like decorative knobs, which have caused recalls in the past).
• Corner posts. Very tall corner posts or decorative cut-outs can catch clothing or cords. Most modern cribs avoid this, but it’s worth a glance.

If you’re buying secondhand, or the crib has been passed down, check it hasn’t been recalled. Manufacturers and safety bodies (CPSC in the US, and the UK’s Office for Product Safety and Standards) publish recall lists you can search by brand and model. Also check that all original hardware is present, missing screws or brackets are a common issue with older or reused cribs.

Size and Space

Measure your nursery before you fall in love with anything. Standard full-size cribs are roughly 132cm by 70cm on the outside, but this varies by brand, so check the exact dimensions rather than assuming. Leave enough space around the crib for a changing routine, for opening the door fully, and ideally for a chair if you’ll be feeding or settling your baby nearby. Also think about where the crib will sit relative to radiators, windows and blinds. Cords from blinds or curtains should never be within reach of the crib, and the crib shouldn’t be positioned directly under a window or against a radiator.

Types of Cribs

Standard Cribs (Cots)

The classic option: four sides, fixed height rails, simple and sturdy. Many convert into toddler beds later by removing one side and adding a guard rail, which stretches their usefulness. A solid, no-frills standard crib is often the best value option, especially for a first baby.

Convertible Cribs

These are designed from the start to transform, usually crib to toddler bed to full-size bed frame, sometimes with a matching headboard and footboard sold separately. They cost more upfront but can genuinely save money over several years if you’re planning to keep your child in the same bed setup as they grow. Just be aware the conversion kits (the extra rails or panels) are often sold separately and add to the real cost, so factor that in before assuming it’s the cheaper long-term choice.

Bedside Cribs (Co-sleeper Cribs)

These attach securely to the side of your bed, with one side lower or open so your baby is right next to you but in their own separate sleep space. They’re popular for the newborn stage because they make night feeds easier without bringing your baby into your bed. Current guidance in the UK recommends room-sharing with your baby for at least the first six months, and a bedside crib fits well with that. Make sure any bedside crib is properly and securely attached to the adult bed frame, following the manufacturer’s instructions exactly.

Portable and Travel Cribs

Lightweight, foldable, and useful for visiting family or for smaller homes where space is tight. They’re generally not as sturdy as a standard crib and the mattresses that come with them are thinner, so they’re best used as a secondary or travel option rather than for full-time nightly sleep over a long period, unless the specific model is designed and rated for that.

Round or Oval Cribs

These make a nice centrepiece in a nursery but tend to be pricier, have fewer mattress options (often needing a custom-fit mattress), and rarely convert into anything else. Worth it if the look matters to you and budget allows, but not the most practical or economical choice.

Mattress and Bedding

The mattress matters as much as the crib itself. It should be firm (not soft or memory-foam-style), flat, and fit snugly with no gaps at the edges. Firm mattresses are recommended because soft surfaces increase the risk of a baby’s face becoming pressed into bedding. Choose a waterproof, wipeable cover and buy a couple of fitted sheets so you’re not caught out during a night-time change.

Keep the crib itself bare for a baby under 12 months: no pillows, no loose blankets, no cot bumpers, and no soft toys inside while your baby sleeps. This is one of the most consistent pieces of safe sleep advice from health professionals, and it’s worth following even if the cot bumper looked lovely in the shop.

Adjustable mattress height is genuinely useful. A higher setting saves your back when your baby is tiny and you’re lifting them in and out constantly. Lower it once your baby can sit up or pull themselves to standing, and lower it again to the floor setting once they can stand holding the rail, to reduce the risk of climbing out.

Material and Build Quality

Solid wood (beech, pine, oak) tends to be sturdier and longer-lasting than composite materials, though it costs more. Metal cribs can also be strong and are often lighter. Whatever the material, check for a smooth, non-toxic finish. Look for a low-VOC or water-based paint or varnish, and ideally a note that it’s free from lead and other harmful substances, particularly important since teething babies will chew on the rails. A teething rail cover (a plastic or silicone strip along the top edge) is a genuinely useful add-on for this exact reason.

Assembly and Practicalities

Some cribs go together in twenty minutes with basic tools, others take a couple of hours and two people. If you’re not confident with flat-pack furniture, check reviews for how straightforward assembly actually is, not just what the box claims. Keep the instructions and any spare screws somewhere safe, you may need them again if you disassemble the crib for a move or to convert it later. Cribs with locking wheels can be handy for cleaning underneath or shifting the crib slightly, but make sure the wheels lock securely so the crib can’t roll once your baby starts pulling up on the rails.

Budget: New vs Secondhand

Buying new gives you certainty about safety standards, no wear on the frame, and a warranty if anything goes wrong. Buying secondhand or borrowing from family can save real money, but only do this with a crib you can fully verify: check the model against recall lists, inspect for damage or missing parts, and never use a crib with drop sides or one that predates current safety standards. Mattresses are generally not worth reusing secondhand, buy a new one to be sure it’s firm, clean, and fits properly.

When to Move On From the Crib

Most toddlers move to a bed somewhere between two and three years old, though there’s no fixed rule. The main signal is whether they can climb out on their own, once that starts happening, it’s time to lower the mattress fully or make the switch, since a fall from a crib is a genuine risk. If your convertible crib is designed to become a toddler bed, this transition is usually straightforward and can help make the change feel familiar rather than disruptive.

Final Thoughts

There’s no single “best” crib, only the one that’s genuinely safe, fits your space, suits your budget, and works for how your family lives. Prioritise the safety basics first: certification, slat spacing, mattress fit, and sturdy construction. After that, let practicality and your own taste guide the rest. Take your time, read genuine reviews from other parents, and if anything about a specific crib’s safety or fit is unclear, ask the retailer directly or check with your health visitor. A bit of extra care now means many peaceful nights ahead.
