Frequently asked questions

Is delivery free?

Yes, to mainland UK. A few Scottish postcodes may cost extra: the list is on our Delivery & Home Assembly page. We don't deliver to Northern Ireland or the islands, but we're happy to help if you can arrange your own delivery from a mainland address nearby. Each bed's page shows its estimated delivery time, which depends on the brand: from the next working day on some beds to around four to five weeks for beds made to order in Belgium or sent from Denmark.

Do you price match?

Yes. If you find any of our beds at a lower price, ask us to match the offer: email info@cosybunks.co.uk with a link to it.

Can you build the bed for me?

Yes, home assembly is available on every bed. On some beds the delivery team builds it on the day; on others professional fitters come after delivery. You'll see the price on each bed's page.

What age is a high sleeper or bunk bed for?

Top bunks and high sleepers are for children aged 6 and over. Mid sleepers usually suit children from about 4. If you're not sure, ask us and we'll check with the maker.

What size mattress do I need?

Most UK single beds take a 90 x 190cm mattress, and many European beds take 90 x 200cm. Each bed's page shows the size it needs. On bunk beds and high sleepers, keep to the maximum mattress depth so the safety rail stays high enough.

Can I return a bed?

Yes. You can cancel within 14 days of delivery; our Returns & Refunds page explains how.

Which bed is best for a small room?

Mid sleepers and cabin beds add storage or play space under a lower bed, high sleepers free the most floor for a desk or sofa bed, and beds with a trundle hide a second bed for sleepovers. Our buying guides compare them.
