Kids Mattresses (UK Sized)

The mattress depends on the size of the bed frame. Common UK sizes include cot bed (70x140cm), single (90x190cm), and small double (120x190cm). Always check the bed frame’s product details first, as most will list the recommended size or allow you to add one to your basket at the same time as the frame. If you’re unsure, you can get in touch with our team and we’ll help you choose the right fit.

Yes, many of the mattresses in this range are compatible with bunk beds, mid sleepers, and high sleepers. For safety, the mattress depth should usually not exceed 15cm on the top bunk or elevated beds. You’ll find specific depth guidance in each product description.

Foam mattresses offer even support and tend to be lightweight, which makes them easier to handle. Sprung mattresses have a core of metal springs and often offer firmer support. There’s no one-size-fits-all - the right choice depends on your child’s age, weight, and how they sleep. If you're looking for a starter mattress for a younger child, a medium support foam option is often ideal.

Some mattresses are single-sided and only need rotating, while others are double-sided and can be flipped as well. We recommend rotating the mattress regularly (around once a month) to help it wear evenly. Check the care instructions on the product listing to see what’s recommended.

We stock a selection of mattresses designed specifically for toddlers moving from a cot to their first bed. These are generally shallower and made with softer support in mind. Look for terms like “cot bed mattress” or “junior mattress” in the product listings.

Yes, all our mattresses come with a manufacturer’s guarantee. The length of this varies by product and brand, but it's usually between one and five years. The guarantee covers manufacturing faults — you'll find full details on each product page.

Most of our mattresses are delivered within 2–3 working days, depending on your location and the supplier. If your order includes a bed frame too, it may come in separate deliveries. For more details, please visit our delivery page.

Yes — you can return a mattress within 14 days, provided it’s in its original, unopened packaging. For hygiene reasons, once the seal is broken, we can’t accept returns unless the item is faulty. More information can be found on our FAQ page and Returns page.
