What size mattress should I buy?
A deep, restorative night’s sleep is becoming more and more necessary for our busy lives, but is becoming harder to achieve. For those who like a lot of space in bed or who share a bed with another, how do you find a bed that’s big enough?

Temperature while sleeping

If you sleep with a partner, a larger bed can help you both maintain your ideal individual sleeping temperature – particularly if one of you is a ‘hot sleeper’. As soon as you create a bit of breathing room in bed, you may find that being too hot is no longer an issue. And if it gets too cold there’s always snuggling, no matter how big the bed is. Temperature control is key. If you do get warm in bed, then it might be worth taking a look at the best mattress for hot sleepers.

Partner disturbance

A larger mattress can also minimise partner disturbance. If this is a factor, also look for a mattress that better isolates movement.

Comfort in Bed

It seems obvious, but a cramped space won’t support your sleep. And while living on the edge may provide an adrenaline rush, lying on the edge is a sure-fire way to wake up tense and grumpy. Choose the mattress size that lets you both have your own space. And with a spring system which runs all the way to the edge of the mattress (like the SleepMaker Miracoil Classic and Advanced ranges), you’ll be supported closer to the edge of the bed, and not feel like you’re about to fall off.


Whatever you get up to in bed, it’s good to have plenty of space to do it in. What a luxury to read the Sunday papers or watch a movie with the kids burrowing under the covers and a furry friend at the end. And if you’d like breakfast in bed more often, it makes sense to allow space for a nice big tray.

One last tip: If your bed resembles a war zone as you and your partner battle it out for the covers, consider selecting a larger top sheet, blanket and doona than your bed size. For instance, if you’re in a King bed, choose Super king covers. Discover our full range of beds from Sleepmaker.
