Toddler bed bundle FAQs

What's included in the toddler bed and mattress bundle?

The complete bundle includes the Transition Toddler Bed, a Roomix toddler mattress sized to fit the bed exactly, and a waterproof, breathable mattress protector. You can also choose the bed on its own or the bed with the mattress only.

What size toddler bed mattress do I need?

None — that's the point of the bundle. The mattress is matched to the internal dimensions of the bed size you choose, so it fits perfectly with no gaps.

Are there any offers on bundles?

Yes. Add the mattress and the mattress protector is free. It comes off automatically in your bag and at checkout, no code needed.

Is the mattress suitable for a toddler moving from a cot?

Yes — the Roomix Toddler Mattress is designed for toddlers from around 18 months. It is breathable, hypoallergenic and firm enough to support growing sleepers safely.

How long does delivery take?

Your bed has a 4–6 week lead time. The mattress and protector are held back and delivered together with your bed — one delivery, everything at once.

Can I customise the toddler bed?

Yes. We can customise almost any feature — rail spacing, opening side or size — for a small fee of £30. Get in touch at hello@roomix.com after ordering.
