Everything You Need to Know About Mattress Sizes and Feels

Do you feel like mattress sizes in Australia vary from place to place? Is it a minefield trying to get your head around how a mattress feels? Here at OMF, we don’t just want you sleeping on the most cOMFy mattress imaginable; we want to make the whole lead-up to finding the best mattress as easy and straightforward as possible. So, let’s clear up any mattress misinformation with this handy guide. 

Mattress sizes 

We’re consistent! Here at OMF, we strictly stick to standard bed dimensions Australia-wide. The following information captures mattress sizes in cm. 

How much space do you need around a bed? 

Although this comes down to personal preference, we recommend choosing a mattress size that allows at least 75cm of space on either side of the bed. This enables you to fit bedside tables comfortably and provides ample area for getting in and out of bed without feeling like you’re sleeping in a closet! That said, if your bedroom is spatially economic, you may want to prioritise the size of the mattress versus the size of the space around it. We don’t disagree - after all, we spend more time on our bed rather than hanging around the sides of it! 


OK, now we have a handle on mattress sizes; let’s look at how they feel. 

Mattress feels 

Whilst sizing is objective, feel is very personal. One person’s perfect ‘firm’ might be another’s ‘fail’. Granted, we’re getting into slightly subjective territory here, but at OMF, we classify the mattress feels very clearly. It’s then down to you and anyone else sharing your bed as to which feel is best! The easiest way to figure that out is to simply visit one of our 50+ nationwide mattress stores. Come in and have a lie-down! You will soon find out the perfect feel for you. We break it down into these key categories: 

Firm feel mattress

A firm feel mattress has the least amount of give and will be fairly rigid to touch. The feel comes largely from the spring tension within the mattress itself - the more springs in your mattress, the firmer the feel. This is a great option if you need lower back support or want to maximise your oxygen intake whilst asleep (that support means your back is less likely to collapse and compress your lungs somewhat). Generally speaking, the heavier the sleeper's weight, the more firmness - and therefore support - they require from their mattress. 

Firm to medium mattress  

A firm to medium mattress offers a combined experience that blends a good level of support with a little more cushioning and ‘give’. Whilst this feel responds faster to pressure than a firm mattress, it won’t have you sinking down into it, either. It’s a great middle-ground for sleepers who want a bit of both worlds.

Medium mattress 

It is probably no surprise that side, stomach and back sleepers across a broad range of weights typically respond well to a medium mattress firmness. As the name suggests, this feel is very much safe and snug in the centre. If Goldilocks were a customer, she’d probably select this mattress! 

Medium to soft mattress 

A medium to soft mattress enters the realm of lower levels of support for the neck and spine. Although there is still a little firmness, this feel is definitely a lot plusher and softer than anything we’ve looked at previously. 

Soft mattress 

A soft mattress can give correct support, cushioning and pressure relief for a petite or average size/shape person. This level of mattress feel can also reduce partner disturbance (e.g. one person in the bed shifting during the middle of the night and, as a result, waking up the other sleeper) should that be a problem.
