Kids bed buying in the UK comes down to four decisions: when to move from the cot, which size lasts longest, what makes a bed genuinely safe, and how to make bedtime something your child actually wants. As bed makers (and parents), here's the honest version of each.

When to move from cot to bed
Most children transition between 18 months and 3 years — the reliable signal is climbing (or attempting to climb) out of the cot, at which point the cot becomes the less safe option. There's no prize for early: if your child is content and contained, waiting is fine.
Which size lasts longest
A standard UK single (90×190cm) is usually the smartest buy: it fits a child of two and still fits a teenager, so one bed and mattress can genuinely last a decade. Toddler-specific beds are cosier and lower but are outgrown by around age five. Full dimensions in our UK sizes guide.
The safety checklist
- Low height: the closer to the floor, the safer the inevitable roll or climb.
- Padded or guarded sides: an upholstered surround or raised edge keeps restless sleepers put — it's why all our kids frames are fully padded.
- Rounded corners: no hard edges at toddler head height.
- Solid, stable frame: a bed that doubles as a pirate ship must not wobble. Check weight ratings and frame construction.
- Snug mattress fit: no gaps between mattress and frame edges.
- Standards and flammability: buy from UK sellers whose beds and mattresses meet current British safety and fire-resistance regulations — ask the retailer to confirm if it isn't stated.

Let them help choose (or at least approve) the bed; keep the cot's bedtime routine identical in the new bed; position it so they can see the door; and resist theming the frame itself — a neutral upholstered bed with themed bedding adapts as tastes change monthly. A supportive children's mattress matters as much as the frame: see our mattress range.
Frequently asked questions
What age is a toddler bed for?
Roughly 18 months to 5 years — after which most children move to a standard single.
Is a single bed too big for a 2-year-old?
No — with a padded surround or guard rail for the first year, a low single is safe and saves buying twice.
What mattress firmness do children need?
Supportive rather than soft — growing spines need a flat, firm-ish surface; avoid memory-foam-soft toppers for young children.
