Best Cots and Cotbeds UK

A cot is the long-stay sleep space: typically 120 × 60cm, used from whenever you leave the Moses basket or bedside crib until your child is ready for a bed. A cotbed is the same idea with removable sides so it converts to a toddler bed (and sometimes a little sofa) — you pay more now and skip a second furniture buy at two.

Which?, MadeForMums, Mother&Baby and Mamas & Papas all treat this as a core category. Clever Mum already covers cot mattresses and travel cots; this guide is the missing frame those sit in.

What actually matters on a cot or cotbed?

• BS EN 716. Bar spacing, strength, stability, entrapment. If the listing does not cite it, walk away — especially on marketplace "cotbed" listings with no UK responsible person.
• Mattress fit. The mattress must be firm, flat and fill the base with no gap around the edge (a 4cm gap is the usual fail). Buy the mattress to the cot's stated size; do not reuse a Moses-basket mattress. Cot mattresses should meet BS EN 16890 — see our mattress guide.
• Three base heights. Highest for the newborn months so you are not bending into a deep box; drop it before they can pull to stand, then drop again. Two heights is workable; one is a back-breaker.
• Teething rails. Toddlers chew the top rail. A replaceable teething strip is cheaper than a chewed heirloom.
• Room and doorway measurements. A sleigh cotbed looks lovely in a showroom and will not turn on the stairs of a Victorian terrace. Measure the room, the door, and the wall you want it against — including skirting and a radiator.

Cot, cotbed or mini cot — who should buy which?

• Standard cot (120 × 60). Cheapest, lightest, easiest to sell on. You will need a toddler bed later. Best if you want to spend the money on the mattress and a sleeping bag instead of furniture that converts.
• Cotbed (usually 140 × 70, converts). The default UK buy for a first child you plan to keep the furniture for. Check what "converts" actually includes — some kits are extra.
• Space-saver / mini cot. For box rooms and boat-narrow terraces. Confirm the mattress size is still a standard you can replace in three years.
• Sleigh / statement cotbeds. Fine if the room is large and you like the look. They are heavier, dearer, and no safer than a plain spindle cot.

What do people get wrong?

• Drop-side cots. Traditional drop-side mechanisms are not what you want — they have a poor safety history. A bedside crib's lockable drop-side is a different, tested design for newborns. On a full cot, fixed sides plus a dropping mattress base is the modern pattern.
• Second-hand mattresses. The Lullaby Trust advises a new mattress for each baby, or one whose history you know completely (no sag, no mould, original cover). The frame can be second-hand if it still meets BS EN 716 and has no damaged bars.
• Bumpers, pillows, nests and loose blankets. None of these belong in a cot for under-12-months, whatever the influencer listing says.
• Putting the cot in a separate room from night one. Room-share for six months is the guidance. A cot in your bedroom, or a bedside crib then a cot, beats a beautiful nursery used from week one.

When should you skip a cotbed and buy a plain cot?

• You already own a toddler bed, or you prefer a floor bed later. Conversion is wasted money.
• You are buying for a short-term rental or a second home. A cheap BS EN 716 cot plus a new mattress is the honest setup.
• The room cannot take 140 × 70. Measure twice.

How does this sit with safer sleep?

Same list as every other sleep product, checked against NHS and Lullaby Trust guidance on 12 August 2026: back to sleep, feet to foot or a well-fitting sleeping bag, clear cot, firm flat mattress, not too hot, smoke-free, in your room for six months. The cot is the container. The mattress is the safety-critical surface. A monitor is optional reassurance, not a substitute.

If you are still choosing between a Moses basket, a next-to-me and a cot, start with the decision guide rather than this shortlist.

How we chose
We shortlisted frames that are widely available in the UK, cite BS EN 716, offer a sensible base-height range, and have a replacement-parts story. Style is last. Commission never affects the order. Prices were checked on 12 August 2026 and will drift.
