Cool Foam vs Hybrid®: Which Simba Mattress Type Suits You Best?
Choosing a new mattress is about more than just deciding how soft or firm you'd like it to feel. The materials inside make a difference too, because they influence how your mattress responds to your body, how it supports you and how comfortable you feel throughout the night.
Simba offers different approaches to mattress construction, including the Cool Foam mattress, available exclusively through Argos, and our Hybrid® range. Both use Simbatex® foam technology, but there's an important difference in how they're made and, therefore, how you feel when using them.
So, which one should you choose? Let's take a closer look at how they compare, what makes each one different and which might suit the way you like to sleep.
What Is the Simba Cool Foam Mattress?
The Simba Cool Foam Mattress is a foam-core mattress designed to offer cushioning comfort alongside technology that helps manage heat.
Its main comfort material is Simbatex® cooling foam, with an open-cell structure to encourage airflow. Graphite infusion helps draw excess heat away from your body, while a high-definition foam base provides zoned support for different areas of your body. Air vents also help keep air moving through the mattress.
Together, these features give you the familiar cushioning feel of foam, with additional technology designed to help manage temperature.
At 15cm deep in the single size, Cool Foam has a streamlined profile and a knitted, quilted cover. You won't need to turn it, either.
The Cool Foam mattress is an Argos exclusive. It's still a part of our wider mattress offering, but you'll find it through Argos rather than on the Simba website. It also comes with a 3-year guarantee.
What Is a Simba Hybrid® Mattress?
A Simba Hybrid® mattress combines engineered foam with patented Aerocoil® microsprings, giving you the cushioning feel of foam alongside responsive spring support.
Made from titanium alloy, the cone-shaped Aerocoil® microsprings compress individually in response to pressure. This helps the mattress adapt to your body, reduce movement transfer between sleeping partners and encourage airflow. Simbatex® foam provides responsive cushioning, with graphite technology designed to help manage excess warmth.
Not every Hybrid® mattress has the same construction, though. Different models introduce additional layers, support zones and comfort materials.
For example, the Hybrid® Essential Mattress offers four layers, five support zones and up to 1,000 springs within a 20cm-deep design. The original Hybrid® Mattress builds on this with five layers, nine support zones and up to 1,900 springs, at a depth of 25cm.
If you'd like additional cushioning and responsiveness, the Hybrid® Pro Mattress introduces two Aerocoil® microspring layers, breathable wool and a deeper steel spring support system.
This gives you plenty of choice, whether you prefer a more straightforward construction or additional comfort features.
All Simba Hybrid® mattresses purchased directly from the Simba website come with a ten-year guarantee, giving you extra reassurance with your purchase.
Cool Foam vs Hybrid®: What's the Main Difference?
Both are designed to give you comfortable support, but they feel different. The main difference comes down to what's inside each mattress. If you enjoy the cushioning of foam, Cool Foam could be a good option. If you'd like the added responsiveness of microsprings, a Hybrid® mattress offers something different.

Which Mattress Is Better for Hot Sleepers?
If you regularly wake up feeling too warm, you should consider temperature regulation when choosing your mattress.
Cool Foam uses open-cell Simbatex® foam, graphite cooling technology and air vents to encourage airflow and help move excess heat away from your body. If you like the feel of foam but tend to get too warm at night, it's worth considering.
Hybrid® mattresses also use Simbatex® foam, but Aerocoil® microsprings create further opportunities for air to move through the mattress. Selected models have additional temperature-regulating features, too. The Hybrid® Pro, for example, combines its foam and microspring layers with breathable wool and a Stratos® cool-touch cover.
Which one feels cooler will depend on your preferences and how you sleep. Your duvet, bedding and bedroom temperature play a part too, so think about your overall sleep setup rather than relying on one mattress feature alone.
A suitable mattress protector can also help keep your mattress clean and protected, whatever type you choose.
Do Cool Foam and Hybrid® Mattresses Feel Different?
Yes. Although both use Simbatex® technology, the addition of microsprings in Hybrid® mattresses changes how they respond when you lie down.
Cool Foam offers a consistent foam-based feel, with layers that cushion your body and provide zoned support. It's a straightforward choice if you enjoy the way foam contours around you.
On the other hand, Hybrid® mattresses combine that cushioning with the responsiveness of Aerocoil® microsprings.
Comfort also varies between Hybrid® models. The Essential and original Hybrid® offer medium-firm support, while more advanced options introduce additional comfort layers. The Hybrid® Pro, for example, adds wool cushioning and a second microspring layer.
There's no single answer to which feels better. Your sleeping position, body shape and preferences all influence how a mattress feels, so consider whether you prefer foam cushioning or the combination of foam and spring responsiveness.
FAQs
Yes, a mattress topper can be used to adjust the feel of your existing mattress, whether it's foam or hybrid. If you'd like a little extra cushioning or want to change the surface feel, a topper could be worth considering. Just make sure you choose the right size and check that it sits securely on your mattress.
Yes. A topper can adjust the feel of an existing foam or hybrid mattress, adding cushioning or changing the surface feel. Just make sure you choose the right size and check that it sits securely.
Think about how much space you both need and whether you tend to disturb each other when moving during the night. Since Aerocoil® microsprings help reduce movement transfer between sleeping partners, a Hybrid mattress may be the optimal choice. Your preferred cushioning and support matter too.
Eligible new mattresses purchased directly from Simba include a 200-night trial, subject to the applicable terms. You can find out more about the 200-night trial and what to expect if you decide to return your mattress.
The Cool Foam mattress is sold through Argos, so its trial and returns arrangements are different. Argos currently provides a 100-night comfort promise for this mattress, so you can request an exchange if it doesn't suit you. Always check the retailer's latest terms before purchasing.
No. The method works best as a flexible framework. Start with the number that targets your biggest problem, adjust the timings to suit you, and build the others in gradually rather than all at once, so each one has a chance to become a habit.
