The memory foam mattress market has grown incredibly quickly in recent years and that means more choice than ever when it comes to selecting a product in this category.

Both Casper and Simba are two of the biggest brands out there and both products have their pros and cons.

This comparison article is going to take a close look at both of these popular mattresses to see where they stand in comparison to the top ones on sale right now.

We’re going to split this article up into the following sections:

• Casper – The Basics
• Simba – The Basics
• What Is The Mattress Made Of?
• What Does the Mattress Feel Like?
• Casper vs Simba – Our Recommendation
• Anything Else To Consider?

So, with the introductions out of the way, let’s start taking a closer look at Casper and how it compares to Simba.

Casper – The Basics

The Casper Original Mattress

The Casper brand was launched in 2014, making them one of the larger players in the memory foam mattress market.

Their Original mattress is the first product they brought to market and it continues to be one of the best selling memory foam mattresses out there right now.

Casper have since branched out to offer other mattresses such as the Casper Wave and the cheaper Casper Essential, but here we’re focusing on the Original.

Price wise, the Casper starts at $595 for a Twin and goes all the way up to $1,195 for a King Size. This makes it a mid-range memory foam mattress option, meaning there are both cheaper and more expensive alternatives out there.

It’s 12 inches thick, which is more than the industry standard 10 inches, and it uses multiple layers of foam to help support a restful night’s sleep (more on what it’s made of below).

The Casper also offers ‘zoned’ support for different parts of your body and claims to have been designed for a great night’s sleep, no matter your preferred position.

Simba – The Basics

The Simba mattress has been around for a few years now and has become one of the best selling mattresses in Europe.

Unlike the Casper, which is a foam-only product, the Simba is what’s known as a ‘hybrid’ mattress, which means that it combines both memory foam and coils to offer a slightly different feel.

The Simba claims to offer excellent comfort and improved cooling, while also providing sturdy support and pressure relief throughout the night.

The Simba mattress has four different layers, each one of which has been included for a specific function. It’s 10 inches thick, which is the standard for mattresses in this category.

The Simba also has zoned support to help relieve pressure for certain parts of the body.

Unlike the Casper, the Simba is currently only available to buy from the official website in Europe, meaning that you can’t get it in the USA right now.

It costs £449 for a Single and £749 for a King Size. Simba also offer free delivery to UK addresses and pick-up and recycling of your old mattress for an extra fee of £30.

What Is The Mattress Made Of?

Now that we’ve covered the basic points of each mattress, let’s take a closer look to see what they are actually made of.


The Casper uses four different layers of foam for its construction. This includes one layer of memory foam and one layer of zoned foam to help support certain parts of the body.

Note that the Casper also comes in a more expensive ‘hybrid’ option – but this article is focusing on the foam-only model.

Here are the four main layers which make up the Casper Mattress:

1) Open Cell Foam – To offer comfort and pressure relief
2) Memory Foam – To help ease pressure
3) Zoned Poly Foam – To offer the right firmness just where you need it
4) High Density Poly Foam – To offer strong support where needed

The use of a zoned layer of foam is what sets the Casper apart from other similar products on the market right now, meaning that there are specific parts of the mattress designed to support your shoulders and hips.


The Simba mattress uses four layers of foam, just like the Casper. Again, like the Casper, the Simba uses zoned support on the bottom layer to offer pressure relief for the shoulders and hips.

What’s different about the Simba is that it uses a layer of coils (springs) to add support, making it a ‘hybrid’ mattress.

Here are the four main layers of the Simba mattress:

1) 5cm of Latex Foam – A cooling comfort layer to help keep you fresh.
2) 2cm Support Foam with Springs – Microcoils encased in foam to cradle your body.
3) 3cm of Memory Foam – Responsive layer to shape to your body.
4) 15cm of Zoned Support Foam – Durable support to offer pressure relief through the night.

The Simba is set apart by the second layer, which contains springs to help offer support. The good thing about springs is that they can also increase airflow through the mattress, and this can help to keep the product cooler throughout the night.

What Does the Mattress Feel Like?

So, now that we’ve looked at what the mattresses are made of, let’s focus on the all-important feel of both products.


The Casper is rated as a ‘medium firm’ mattress, like most of the other products in this category.

It has a slightly firmer feel than most of the other similar mattresses out there, but this also varies from person to person, especially with the use of the zoned support layer.

Generally speaking, back and stomach sleepers tend to prefer a firmer mattress, with side sleepers usually looking for something softer.

However, the fact that the Casper uses zoned support suggests that this product has actually been designed with side sleepers in mind.


The Simba is also rated as a ‘medium firm’ mattress.

There is a good amount of sinkage in the first two layers but below that, there is enough support to keep you feeling comfortable and not ‘stuck in the bed’.

The Simba is a tad softer than the Casper in our opinion, but it’s worth remember that everyone has a slightly different reaction to what mattresses actually feel like.

Because this is a slightly softer mattress, the Simba is probably better suited to side sleepers – although the manufacturers insist that it will be comfortable no matter which position you sleep in.

Casper vs Simba – Our Recommendation

So, how do the Casper and Simba compare?

As you’ve probably already guessed, these are two very similar products, with both offering zoned memory foam support.

The Casper is slightly thicker than the Simba but both mattresses offer solid support with a softer feel in the top two layers.

The one thing that the Simba has going for it is its use of coils to make it a hybrid mattress.

As mentioned above, coils or springs can increase the airflow in the mattress and help with cooling, which some people can find to be an issue with foam-only mattresses.

For that reason, we are going to pick the Simba as our favorite product here – but you’re not going to go too far wrong by siding with Casper either. They are both very good mattresses.

Anything Else To Consider?

Just remember that the only way to be sure that a mattress is right for you is to actually sleep on it for a few nights.

Both the Casper and the Simba come with 100 night home trials, meaning that you can try it out and return it for a full refund during that time if you’re not happy with it.

Wrapping Things Up – Final Thoughts

That brings us to the end of our comparison between the Casper and Simba mattresses.

All in all, these two products are pretty similar. They have similar price tags and both offer zoned support.

The main difference is that the Simba is a hybrid mattress which also uses a layer of springs as well as foam. And we rate it just above the Casper for that reason.
