FAQs about king single bed bases

What exactly is a King Single bed, and how is it different from a regular king?

A King Single bed is much narrower than a regular king – it's 107cm wide compared to a king's 183cm. Both are the same length at 203cm. Think of it as a single bed with the length of a king —perfect when you need that extra legroom but don't have extra space for the full width of a king bed.

Will my existing King Single mattress fit your bed bases?

Absolutely! Our King Single size bed bases are designed to fit all standard King Single mattresses (107cm x 203cm). We've made sure the dimensions are spot-on, so whether you're buying our mattress or already have one, you're good to go. 

How hard is it to assemble these bed bases?

We've designed our bases to be super straightforward to put together. Most people get it done in about 30-45 minutes. Everything you need comes in the box, including clear instructions. No special tools required—just a bit of patience and maybe a coffee break halfway through!

Can I buy just the base without a mattress?

Of course! While we'd love you to try our award-winning mattresses, we totally understand if you just need a new base. You can purchase any of our bases separately – they work brilliantly with any King Single mattress.

How do I know if a King Single is the right size for my space?

Great question! Before you buy, take a sec to measure your space. King Single Beds are ideal for small-to-medium rooms where a double bed feels too big and a single feels too small. They’re especially popular for teens, taller kids, guest rooms, and even foot-of-the-bed setups in larger spaces.
