Do you need a cot, a cot bed, or a full nursery set?
You need one clear, flat, separate sleep space in your room for at least six months. A cot or a cot bed can be that space. Matching drawers, a changing top and a canopy are furniture, not safer sleep. A Moses basket is optional convenience. Buy the mattress as carefully as the frame.
The Lullaby Trust’s safest place is their own clear, flat, firm separate sleep space in the same room as you (page last reviewed 1 February 2025; checked 13 Aug 2026). It does not require a themed nursery. See Moses basket vs next-to-me if you are choosing portable vs bedside, and cot mattresses for the surface test.

Cot or cot bed — which should you buy first?
A cot bed that converts later can be the only sleep furniture you buy if it fits in your room now. A smaller cot or compact crib wins if a cot bed will not go beside your bed for six months of room-sharing. Do not park the baby in a nursery from night one to justify a bigger frame.
| Frame | Choose if | Skip if |
|---|---|---|
| Compact crib | The parents’ room is tight | You would put it in another room from night one |
| Standard cot | You want a simple frame and a known mattress size | You already know you want a toddler bed later from the same piece |
| Cot bed | It fits in your room now and you will convert it later | It only fits in a nursery you will not sleep in |
| Full furniture set | Almost never as a first buy | Bumpers and canopies are in the bundle |
What mattress and gaps rules still apply to a cot bed?
The same rules: firm, flat, waterproof, snug, new. No gaps around the mattress. No pillows, duvets, bumpers, nests or weighted blankets. A cot bed is still a clear cot. Decorative wide bars and “cloud” mattresses fail the test. Second-hand frames are easier to reuse than second-hand mattresses.
The NHS says the cot mattress should be new (checked 13 Aug 2026). Pair this page with the mattress guide rather than trusting a furniture bundle’s foam. Sleeping bags live on TOG.
Which cots and cot beds are worth comparing in the UK?
Compare a cot bed with an adjustable base and a compact crib for the parents’ room — not a ranked oak set. We have not assembled them. Skip canopies. Measure the room before you fall for a showroom. Awin hops can sit beside Amazon when those URLs are live.

Cot bed with drop-side or adjustable base
A cot that converts later can be the only sleep furniture you buy. The mattress still has to be new, firm, flat and snug.
Skip if: It will not fit in your room for six months of room-sharing, or the bars look decorative and wide.

Compact crib for the parents’ room
If a full cot does not fit beside the bed, a compact crib is the space solution. Same mattress rules. Same clear-cot rules.
Skip if: You were going to put it in a nursery from night one.
When should you skip a nursery furniture bundle?
Skip it if the cot will not fit in your room. Skip bumpers, pillows and quilts even when they “match”. Skip a changing table you can replace with a mat on a chest. A travel cot is a different job — grandparents and first nights away — see [travel cots](/guides/travel-cot-uk). Spend first on the mattress, not the theme.
Order of spend is still on newborn essentials. Furniture last.
Can you start with a Moses basket and add a cot later?
Yes, if the basket is a clear, firm, flat space in your room and you accept it is outgrown when they roll. You do not need both at once. Adding a cot when they outgrow the basket is rational. Buying both “just in case” is how spare rooms fill with unused frames.
The Moses vs next-to-me guide is the decision tree. This page is the longer-life frame once that first space is outgrown — or instead of it, if a cot already fits.
Frequently asked questions
- What is the difference between a cot and a cot bed?
- A cot is a baby sleep frame. A cot bed is designed to convert into a toddler bed later. Both still need a firm flat snug mattress and a clear interior. Fit in your room for six months matters more than the conversion story.
- Does a newborn need a cot straight away?
- They need a safe sleep space in your room. That can be a cot, a compact crib or a Moses basket. A full nursery next door is not the starting setup The Lullaby Trust describes.
- Can I use a second-hand cot?
- A frame with a known history and intact parts is the easier reuse. Buy the mattress new unless you can prove the old one is firm, flat, unstained and the right size. Skip unknown-history bundles.
