Whether for the kids’ rooms or guest bedrooms, king single trundle beds are roomy and functional pieces of furniture that solve the problem of limited space.

A trundle bed is essentially two beds in one. The bottom bed sits very low to the ground and tucks in nice and snug under the main top bed, freeing up space when the spare bed isn’t needed and providing a speedy solution for sleepovers. Called ‘trundles’ because of their handy castor wheels, these genius space savers are guaranteed to get years of use in busy families, and in a king single size, they’ll see the kids right through from toddlerhood to the teenage years.

Ready to find the perfect bed for the kids’ rooms? We’ve scoured the country and shortlisted the king single trundles that the whole family will love.

Benefits of King Single Beds (especially with trundles!)

• They are perfect for growing kids – Singles quickly become a bit too snug for fast-growing kids, but king singles can easily see them right through to the teen years.
• The spare bed is out of sight – With a trundle that slides right under the main bed, you’re able to keep the floor clear space and the room looking tidy even while houseguests are still around.
• You’re all set for sleepovers – Whether it’s cousins or best mates, sooner or later you’ll have little houseguests under your roof. A trundle keeps kids together in the same room but in the comfort of their own beds.
• The trundle doubles as storage space – And no family can ever have too much storage! Instead of storing a mattress, use the space for bedding, toys and linen.
• They look great! – More luxe than a single, but not as imposing as a double, a king single looks just right. Paired with a beautiful quilt cover, gorgeous bedside tables and a decorative rug, it’s a room you’ll be happy to invite guests into.

What size is a king single mattress?

In Australia, a king single mattress measures 107cm x 203cm, which is wider and longer than a single which typically measures 92cm x 88cm.

And no, a king single is not the same as a double mattress either, which is bigger in width but shorter in length at 138cm x 190cm.

Can adults sleep on trundle beds?

Absolutely. Trundles aren’t just for kids (although kids do tend to love them). Most well-made wooden trundles are more than capable of supporting an adult, especially when paired with a quality mattress. King single trundle beds are especially brilliant for adults because of the extra length they offer, which is more than a double bed.

Do trundle beds use regular mattresses?

Yes, trundles usually pair up with regular mattresses of your choice. Just be sure to check the size is correct for the bed you’ve chosen.

Can a trundle be added to any bed?

You can only add a trundle to your existing bed if you have enough space underneath for it to fit. Get out your tape measure and check the distance from the base of the bed to the floor, then compare this with the trundles you’re looking at.

And if you plan to keep the trundle bed made up for a guest staying a few nights allow some extra space for the bedding.
