Questions & Answers (8)

Answers from the Cuckooland team.

Is the mattress rolled/vacuum-packed and how long until it expands?

Vacuum-packed mattresses can look smaller than the stated dimensions while compressed. Once removed from the packaging, give the mattress enough time to expand fully before measuring it.

Can I return a mattress?

Opened or used mattresses and pillows can't be returned for health and hygiene reasons. Unopened mattresses in their original packaging follow our normal returns procedure.

Do you take away my old furniture?

No. Removal and disposal of unwanted furniture or mattresses isn't included, so please arrange this yourself. We recommend waiting until your new order has arrived.

What are the full dimensions of this product?

Full dimensions are on the product page, in the specifications and the dimension diagram; all measurements are approximate. If the measurement you need isn't listed, contact us and we'll check with the manufacturer.

When will an out-of-stock item be back in stock?

Out-of-stock items can often still be pre-ordered, using the estimated lead time shown on the product page. Restock dates are approximate and can change. Once stock arrives, pre-orders are dispatched straight away for delivery the next working day.

What does the colour look like in real life / is it closer to X or Y?

Colours can look slightly different in photos because of lighting and screen settings. Where available, order a free fabric sample from the product page to see the colour in person.

Can I return an item if I change my mind, and how?

Yes. You can cancel within 14 days of delivery and then have 14 days to send the item back. Items must be returned "as new": not assembled, modified or made to order. Email customerservice@cuckooland.com with your order number and photos of the item and boxes; you'll get a reply within 48 working hours. If you ask us to collect, a collection charge is deducted from the refund. Opened or used mattresses and pillows can't be returned for hygiene reasons.

What payment methods do you accept?

We accept debit and credit cards, PayPal, Apple Pay and Google Pay. Klarna, Clearpay and V12 Retail Finance are also available on eligible orders. The options for your order are shown at checkout.

A bed is named after the mattress size it's built to hold, so a king bed frame takes a king mattress. The frame itself is usually a little bigger. European (continental) sizes aren't the same as UK ones and can vary between brands.

Bunk beds and high sleepers have a maximum mattress depth set by the manufacturer, so the safety rail stays high enough.

Before you order, check the full dimensions on this product page and measure the space in your room.
