Stokke Sleepi Mini vs Charlie Crane Kumi Crib: The £414 Rocker Includes Its Mattress, the £435 Oval Can Grow Into a Bed

COMPARISON · NURSERY & SLEEP

Most first-bed comparisons are about bedside cribs: which one drops a side, which one slots against your mattress. This one is different. The Stokke Sleepi Mini and the Charlie Crane Kumi are both standalone cribs. Neither attaches to your bed. Both are made from beech, both cost a little over £400, and both are designed for roughly the first six months. They are the kind of crib parents buy because they want the first bed to look like a piece of furniture rather than a piece of kit.

Look closer and they solve the first months in opposite ways. The Kumi is a modern take on the rocking cradle: a mesh cocoon laced onto a beech hoop that sways side to side on solid wooden skids, and it arrives with its own coconut-fibre mattress. The Sleepi Mini is an oval cot in miniature: four mattress heights, lockable swivel wheels so you can roll it from bedroom to living room, and a route to grow into the full-size Sleepi bed with a separate extension. Its mattress is extra.

So the price tags hide the real trade-off. On paper the Kumi is £21 cheaper. Mattress for mattress, the gap is £40. And only one of them still has a job once your baby starts pulling up on the sides. We compared both on published dimensions, weights, warranty terms and what is actually in the box, alongside the themes that come up again and again when parents talk to us about first cribs.

How we picked the 2

We started from the cribs BubsNest parents add to their Nests and filtered for standalone newborn sleep spaces from established nursery brands, in stock with a UK retailer we work with. Bedside cribs were ruled out on purpose: they are a different decision, and we have covered them plenty. That left two premium, beech-framed cribs at almost the same price but with opposite design ideas. We then checked each brand's published specifications, the retailer listing and what is included in the box, and weighed them against the recurring questions parents send us about first cribs: how long will it last, will it fit our room, and what else do we need to buy?

What to look for in a standalone crib

Lifespan before the first birthday. Almost every crib, moses basket and cradle is designed for roughly the first six months, or until your baby can roll, sit or pull up. After that you need a cot. A crib that converts into the cot saves money and a second assembly. One that does not is a six-month purchase however beautiful it is.

The mattress and its sheets. Newborns should sleep on their back on a firm, flat, well-fitting mattress with no gaps around the edges. Check whether the mattress is included, what it is made from and whether the size is standard. Oval and non-standard mattresses need bespoke sheets, and you will want at least three.

Height. A higher mattress position means less bending, which matters after a caesarean or with a sore back. Adjustable heights also let the base drop as your baby gets more mobile.

Moving it around. If you want daytime naps in the living room and nights in your bedroom, wheels or a light frame help. Measure your doorways.

Motion. Rocking can help settle a baby, but a rocking crib should come to rest flat and stable once your baby is asleep. Keep the sleep space clear: no pillows, bumpers or loose bedding.

Washability and airflow. Mesh sides are breathable and soft; wooden spindles are easier to wipe and do not need laundering. Either works, but think about which you would rather clean after a nappy leak.

1. Stokke Sleepi V3 Mini Crib / 10 · Best for growing into a bed

The Sleepi Mini is the newborn version of Stokke's oval Sleepi bed. It is made from FSC-certified beech with no sharp corners, measures 82 x 67 x 87cm and weighs 16.4kg. The 67cm width is deliberate: it rolls through a standard internal doorway on four lockable swivel wheels, so the same crib can do daytime naps downstairs and nights in your room.

Its biggest advantage is what happens at six months. On its own, the Mini is a crib from birth to around six months. Add the Sleepi extension kit, sold separately, and it becomes the full-size Sleepi bed, which Stokke designs to last until around five years. You are paying for the first chapter of a much longer piece of furniture, not a six-month crib.

What parents love

• Four mattress heights. The base starts high for the newborn weeks and steps down as your baby gets more mobile. Parents recovering from a caesarean tell us the top position is the feature they did not know they needed.
• Wheels that lock. Parents we hear from regularly like being able to roll it into the kitchen for naps and back to the bedroom at night without it feeling like moving furniture. The lockable castors keep it planted when you want it still.
• The oval shape. No corners to bump into on a dark landing, and the rounded form feels enclosed for a tiny baby without solid walls.
• Built to last. Solid beech and a three-year warranty once registered with Stokke. We hear repeatedly from parents that it is the one nursery piece they plan to keep for a second child.

What to know before you buy

• The mattress is extra. The £435 price is for the frame only. With the Sleepi Mini mattress it is £454, and the extension kit for the full bed is a separate purchase on top.
• Bespoke sheets. The oval mattress needs Sleepi Mini sheets. Standard crib sheets will not fit properly, so budget for at least three.
• Heavy and wide. At 16.4kg and 67cm wide it takes up more floor than the Kumi, and the wheels roll rather than rock, so there is no hands-free sway.

Best for

• Parents who want one piece of furniture from birth to the toddler years
• Homes where the crib moves between rooms during the day
• Anyone who wants a high mattress position for easier lifting
• Families planning to reuse it for a sibling

2. Charlie Crane KUMI Crib + Coco Mattress / 10 · Best for rocking

The Kumi is Charlie Crane's reinvention of the rocking cradle. A breathable mesh cocoon with a cotton base is laced onto a beech plywood hoop, which sits on a white epoxy-coated metal frame and solid beech skids. The result rocks gently side to side, the oldest settling motion there is, and measures 81 x 56 x 72cm. It is compliant with the European crib standard EN1130:2019.

At £414 it comes with a 68 x 40 x 5cm natural coconut-fibre mattress in an organic cotton cover quilted with organic wool. That makes it the cheaper crib to have ready on day one. The catch is lifespan: like any cradle, it is for use from birth until your baby can sit up, kneel or pull themselves up, and there is no conversion. When that milestone arrives, the Kumi is finished as a bed.

What parents love

• A real rocking base. We hear repeatedly from parents that a gentle push is often enough to settle a fussing baby, and that the crib comes back to level on its own. The Sleepi Mini can be rolled to and fro, but only the Kumi sways.
• Mattress included. The coconut-fibre mattress is firm and naturally breathable, and you do not need to find one that fits.
• Soft, see-through sides. The mesh cocoon lets air move and lets you see your baby from across the room. It unlaces and goes in the washing machine at 40°C.
• Small and light. At 56cm wide and around 9kg boxed, it suits a corner of a bedroom where a full crib would not fit.

What to know before you buy

• Six months, roughly, then done. Once your baby can sit up or pull up, it has to go. You will be buying a cot as well.
• One fixed height, no wheels. The base sits around 44cm off the floor, so there is more bending than with the Sleepi Mini on its top setting, and moving it means carrying it.
• Lacing and a shorter warranty. Re-lacing the cocoon after a wash takes patience, and the warranty is one year against Stokke's three.

Best for

• Parents whose baby settles best with gentle motion
• Smaller bedrooms where every centimetre of floor counts
• Families who already have a cot lined up for six months
• Anyone who wants a natural-fibre mattress included in the price

How to choose

Choose the Stokke Sleepi Mini if you are thinking beyond the first six months. The four mattress heights make the newborn weeks easier on your back, the wheels make it a crib for the whole house, and the extension kit turns it into the full Sleepi bed rather than leaving you with a crib in the loft. Budget £454 with its mattress, plus bespoke sheets, and treat the extension as a later purchase that replaces buying a separate cot.

Choose the Charlie Crane Kumi if rocking is the point. It is the only one of the two that genuinely sways, it fits a smaller room, and £414 covers the crib and a natural mattress. Go in knowing it is a beautiful six-month bed, and that you will be buying a cot when your baby starts to sit or pull up.

The short version: the Kumi is cheaper on day one, the Sleepi Mini is cheaper by the first birthday if you would otherwise buy a cot as well.
