What are the different types of mattresses?

Innerspring or pocket spring mattress

Innerspring mattresses are generally made up of three layers, the middle layer is where the spring coils live. The coils are then surrounded by ‘support layers’: a plush topper and a foam base.

Memory foam or foam mattress

There are three main types of memory foam – traditional, open cell and gel memory foam. All three work in a similar way where they mould to the contours of your body for a more personalised support. However, if you tend to run hot when you sleep, we’d recommend opting for an open cell or a gel-infused memory foam mattress as traditional memory foam tends to trap more heat in.

Hybrid mattress

The best of both worlds. A hybrid mattress has a cloud-like foam layer at the top with pocket springs in the middle for ultimate support.

Mattress in a box

If you’re in the midst of moving, opting for a mattress-in-a-box option may be worthwhile. Generally, boxed mattresses are memory foam mattresses, but some hybrid mattresses are also able to be packaged neatly for your convenience.

Which type of mattresses are best  

Choosing the best mattress depends on numerous factors, including your preferred level of support (from soft to firm), and whether you’re a back, side, or stomach sleeper.

Side sleepers

If you sleep on your side, it’s recommended to opt for memory foam or foam mattresses in general. This is because traditional, gel-infused, and open cell memory foam mattresses reacts to your body heat and pressure and moulds to the contours of your body ensuring a more comfortable and ergonomic sleep.

Back sleepers

If you sleep on your back, you may find innerspring mattresses offer a bit more support. Although, there are foam mattresses that also work well for back sleepers, it is high-quality innerspring mattresses that offer better back support.

Stomach sleepers

Similar to side sleepers, stomach sleepers need pressure relief at various parts of your body. Stomach sleepers may prefer foam mattresses or hybrid mattresses for a good night’s sleep.

Which mattress brand is best?   

Again, choosing the best mattresses depends on your preference, budget and sleep needs. Brands like Emma Sleep and Ecosa offer trials so you can test the best mattress type and varying firmness levels for you.
