Best Cots UK 2026 Every Budget Tested
Six cots reviewed from £115 to £600 — honest verdicts on safety, build quality, mattress fit, and how long each one actually lasts your child.
Is your baby’s sleep environment safe?
Our Safe Sleep Checker walks through every element of your baby’s cot setup against current NHS and Lullaby Trust guidance.
What to Know Before You Buy
Most parents move their baby from a bedside crib to a full cot at around six months — when the baby begins to roll or sit, making an open-sided crib unsafe. A full cot provides the firm, flat, enclosed sleep surface your baby needs from that point until they are ready for a toddler or single bed, typically between 18 months and 3 years.
Cot vs cot bed — which do I need?
A cot is a standard sleep unit, typically lasting to around 18 months to 2 years. A cot bed is larger and converts to a toddler bed by removing one side — extending the investment to age 4 or 5. If space allows, a cot bed is usually better value over time. Several recommendations in this guide include convertible cot beds. Our Nursery Planning Tool helps you work out what fits in your space before you buy.
Mattress matters as much as the cot
The cot provides the frame; the mattress determines sleep safety. Always buy a new mattress — the evidence linking used mattresses to increased SIDS risk is sufficient that the NHS advises against it. The mattress should fit the cot exactly with no gaps larger than 4cm on any side. See our safe sleep guide for the full NHS and Lullaby Trust guidance.
Adjustable mattress height
Most cots offer two or three mattress height positions. Start at the highest position for a newborn — easier to lift the baby in and out. Drop to the lowest position as soon as your baby can pull themselves up, to prevent them climbing out.
① Best Overall
The Stokke Sleepi is unlike any other cot in this guide. Its oval shape grows with your child through five configurations — from a newborn mini crib all the way to a junior bed that fits a child up to 10 years old. The Norwegian beech wood construction is exceptional, and the oval form means no sharp corners to negotiate in a nursery. The investment is significant upfront but when spread across the full decade of use — replacing multiple cots and beds — the cost per year is more reasonable than it first appears. If your baby budget can accommodate it, this is the last sleep surface you will need to buy for years.
② Best Budget
The IKEA Sundvik is quite possibly the most purchased cot in the UK and with good reason. Solid pine construction — not MDF or chipboard — at a price that defies expectation. Two adjustable mattress height positions, slat spacing that meets current safety standards, and clean Scandinavian styling that works in almost any nursery. It does not convert to a toddler bed, which means you will need to buy again, but at £115 the total spend including a replacement toddler bed can still undercut most single-purchase alternatives. If you are planning the full nursery budget, our Baby Budget Calculator makes these trade-offs easy to see.
③ Best Mid-Range
The Silver Cross Bromley is a confident mid-range choice from one of the UK’s most trusted nursery brands. Solid wood construction with a clean, classic profile that wears well — not a cot that looks dated after a year. Three mattress height positions cover the full newborn to toddler transition, and the cot converts to a toddler bed using a conversion kit, extending use to around age 4. Compatible with standard 60x120cm mattresses which are widely available and competitively priced.
④ Best Convertible
The Boori Neat offers the most complete conversion journey of any cot in this guide. Made from sustainably sourced Araucaria wood with a durable, wipe-clean finish, it converts from cot to toddler bed to a small sofa — with all conversion parts included in the purchase price, not sold separately. The Neat fits Boori’s own mattresses which are widely stocked. If you want a single purchase that sees you through the full sleep transition without buying conversion kits separately, this is the one. It connects naturally to our nap transitions guide when your toddler is ready to drop to one nap and eventually move to a bed.
⑤ Best Value
The Mamas & Papas Franklin sits in the sweet spot between the IKEA budget option and the premium mid-range. Solid wood with a clean, contemporary profile, three mattress height positions, and a toddler bed conversion included. The Franklin is also compatible with Mamas & Papas’ own fitted sheets and accessories — useful if you are buying a full nursery set. Good quality for £250 and one of the better-looking cots at this price. If you are building out your full nursery list, our complete baby buying guide covers what to prioritise and what can wait.
⑥ Best Classic
East Coast Nursery has been manufacturing UK nursery furniture for over 30 years and the Langham exemplifies what the brand does well — solid, no-nonsense construction at a fair price. Solid pine, three mattress height positions, standard 60x120cm mattress sizing, and a traditional style that suits classic nursery schemes. It does not convert to a toddler bed, which keeps the price down significantly. For parents who prefer a traditional aesthetic and want a British brand with a long track record over a cheaper flat-pack alternative, the Langham is the obvious choice. Pair with our best baby sleeping bags guide to complete the safe sleep setup.

Buying Guide
What size mattress do I need?
The standard UK cot mattress is 60x120cm. Most cots in this guide use this size, which makes mattresses widely available and competitively priced. The Stokke Sleepi uses an oval mattress which must be purchased from Stokke directly or approved suppliers. Always confirm the mattress size before buying — a mattress that fits too loosely is a safety risk.
When should I order?
Order no later than 32–34 weeks pregnant. Some cots take two to three weeks to arrive and need assembling before your due date. Use our Due Date Buying Timeline to plan the full sequence of nursery purchases. Our Nursery Planning Tool also helps you confirm everything fits in your room before anything arrives.
Is a cot or cot bed better value?
A cot bed costs more upfront but typically replaces both the cot and first toddler bed. If you are planning to have more than one child and can store the cot between uses, a standard cot can be a more flexible choice. If this is your only planned child, a converting cot bed often works out cheaper over the full period of use. Run the numbers for your situation with our Baby Budget Calculator.
Which cot should you buy?
For most families the honest answer is either the IKEA Sundvik or the Mamas & Papas Franklin. The Sundvik does everything a cot needs to do at a price that leaves money for everything else on the nursery list. The Franklin adds a toddler bed conversion for £135 more, which is genuinely good value if you plan to use it.
The Stokke Sleepi is exceptional but the premium is only justified if you will use the full decade of configurations. If you are planning to stop at one child and will not be passing the cot on, the maths rarely works out in the Sleepi’s favour compared to a mid-range cot followed by a standard toddler bed.
