Toddler Beds
Toddler bed vs crib conversion
If your crib converts, conversion is free and the bed already smells right to your child. That is a strong argument — here is when it loses.

How we chose
We are a small publisher, not a testing lab. We don’t buy, assemble or sleep in the beds we write about, and we won’t pretend otherwise. What we do instead is read the published specifications and check them against the rules that actually govern children’s beds in the United States: the federal standard for children’s bunk beds (16 CFR Part 1513), the ASTM F1427 requirements it incorporates, and the American Academy of Pediatrics’ guidance on upper-bunk age. Where a manufacturer publishes no number, we write “not published by the manufacturer” rather than guess — that absence is itself worth knowing. We read owner feedback at volume for the things specs can’t tell you, and we label it as signal, not proof.

Decide for me
Convert the crib if yours converts, the conversion kit is included or cheap, and the room does not need the crib for a new baby. Free, familiar, and one fewer object to buy.
Buy a standalone toddler bed if the crib is needed for a sibling, if the conversion kit costs a meaningful fraction of a new bed, or if the child associates the crib with being confined and you want a visible fresh start.
Do neither if your child is nearly four — go straight to a twin with a rail and stop buying beds. See best toddler beds for why we rank a twin in a toddler bed roundup.
Side by side
| Crib conversion | Standalone toddler bed | |
|---|---|---|
| Cost | Free, or the price of a conversion kit | A new bed |
| Familiarity for the child | High — same bed, same place | A new object |
| Frees the crib for a sibling | No | Yes |
| Rail coverage | Usually one open side | Often rails on all four sides |
| Takes the existing mattress | Yes | Usually yes |
| Adding a rail later | Awkward — needs a crib-specific rail | Straightforward |
| Feels like a milestone | Less so | More so |
Safety
Broadly comparable, with one asymmetry worth knowing. A converted crib typically has one fully open side, because the dropped rail is the opening. A standalone toddler bed often has short rails on all four sides with a gap in the middle of one. Neither is a barrier in the sense a bunk guardrail is; both are low enough that it matters less.
The practical difference shows up when you want to add a rail. Converted cribs give a universal rail almost nothing to grip, which is why crib-specific rails exist as a category.
Cost
Conversion wins unless the kit is expensive. Check before assuming it is free: many convertible cribs require a toddler rail sold separately, and on some models that kit costs a substantial fraction of an entire standalone toddler bed. That is a genuinely annoying discovery to make at the point of conversion, so make it now.
The sibling question
This decides it for a lot of families. If a new baby is coming, the crib is needed as a crib, and converting it is not an option. Note the timing advice you will hear from most pediatric sources: move the older child well before the baby arrives, so the two events are not connected in the child’s mind.
Longevity
Both are limited by the same crib mattress footprint, so neither wins on how long it lasts. A converted crib does tend to look like a crib for longer, which some children mind and most do not.
Who should choose neither
Families whose real problem is that the child will not stay in bed. That is not a furniture problem and a different frame will not fix it — see transition troubleshooting. And families considering a floor bed, which is a third option this comparison deliberately leaves out.

The first bed out of the crib
Dream On Me Emma 3-in-1 Convertible Toddler Bed
Dream On Me
Publishes a weight limit, runs four side rails and sits low enough that falling out is barely an event.
| Guardrail height above mattress | Four integrated side safety rails (height not published) |
|---|---|
| Stated weight limit (per bunk) | 50 lb |
| Manufacturer minimum age | Not published by the manufacturer |
| Mattress thickness ceiling | Uses a standard crib mattress |
| Materials / construction | Solid pinewood, GREENGUARD Gold certified |
What works
- Low-to-floor design means a roll-out is inches, not feet
- Four side rails come with the bed rather than as an accessory
- Takes the crib mattress you already own
- Converts to a table and two chairs when the bed is outgrown
What doesn’t
- 50 lb limit is reached by a lot of five-year-olds
- Crib-mattress footprint is genuinely small for a tall four-year-old
- Conversion to table and chairs is charming but rarely used
The catch: The 50 lb limit is the real lifespan of this bed, and it is shorter than the marketing implies. Plenty of children hit 50 lb around age five, which is well before they are ready for a twin.
A straightforward crib-to-bed step
Delta Children Canton Toddler Bed
Delta Children
The plain, sturdy wooden toddler bed that shows up on every shortlist, and it earns the spot on build rather than features.
| Guardrail height above mattress | Not published by the manufacturer |
|---|---|
| Stated weight limit (per bunk) | Not published by the manufacturer |
| Manufacturer minimum age | Not published by the manufacturer |
| Mattress thickness ceiling | Uses a standard crib mattress |
| Materials / construction | Wood frame with non-toxic finish |
What works
- Low, simple and unfussy — nothing to break
- Takes the crib mattress already in the room
- Integrated side rails on both sides
- Widely stocked, so replacement parts are findable
What doesn’t
- Neither a guardrail height nor a weight limit is published
- No conversion path — it is a toddler bed and then it is done
- Plain styling, if that matters to you
The catch: Delta does not publish a weight limit for this bed anywhere we could find. For a low toddler frame that matters less than it would on a bunk, but it is still a number a manufacturer should be willing to state.
Questions parents actually ask
Is it better to convert a crib or buy a toddler bed?
Convert, if the crib converts and the kit is cheap and nobody else needs the crib. Buy standalone if any of those is false.
Do all cribs convert to toddler beds?
No. Check your model, and check whether the toddler rail is included or sold separately — on some cribs the kit costs a large fraction of a whole bed.
How do you add a rail to a converted crib?
With a rail designed for converted cribs. Universal rails have very little to grip on a crib frame.
When should you move a toddler before a new baby arrives?
Well before, so the move and the baby are not linked in the child’s mind. Several weeks at minimum is the common guidance.
Does a converted crib use the same mattress?
Yes — that is part of the appeal.
