There are four layers to the Simba Hybrid topper.

These layers are:

  • Super soft, breathable top cover

  • 2,500 Aerocoil 20 mm pocket springs enclosed in 100% polyester pockets

Simba hybrid mattress topper materials

The hybrid composition of the Simba mattress topper is unique.

Most mattress toppers are pure foam toppers, but the Simba topper combines both foams and conical pocket springs. 🌀

These add bounce and help cool the mattress topper.

What does sleeping on the Simba mattress topper feel like?

Mattress toppers are designed as comfort layers to change the way your mattress feels.

In general, they are meant to add an additional layer of softness and comfort to firmer mattresses.

How firm is the Simba mattress topper?

It's difficult to give a set degree of firmness to mattress toppers in the way you would give a mattress a firmness level.

This is because the firmness of the topper is directly influenced by the firmness of the mattress underneath.

Most toppers, though, including the Simba topper, are generally designed to be medium firm. 👍

They are usually meant to make your sleeping surface a little softer and give your mattress an instant boost in comfort.

How comfortable is the Simba topper?

The Simba topper is unique in that it combines Simbatex synthetic latex and pocket springs.

This has two effects:

  • The foam provides body-contouring support and pressure relief that's comfortable without being too constrictive, as memory foam often is.
  • The springs provide a gentle bounce-back, so you can move easily on the topper, and they adapt well to your body for tension relief.

The Simba topper is particularly well-suited to side sleepers who are sleeping on a slightly firmer mattress. 👌

This is because the topper allows for more sinkage, which can help correct spinal alignment.

How does this work?

In order to sleep correctly in the side position, the hips and shoulders have to sink in a little more deeply, while the head and feet remain lifted. ✅

This ensures optimal spinal alignment.

Optimal spinal alignment

If your mattress is too firm, pressure points will build up in the hip and shoulder areas, causing back pains and aches.

Adding a topper to the mix will allow for a little extra sinkage, ensuring spinal alignment, and keeping you pain- and ache-free.

Does the Simba topper sleep hot?

Many of the best mattress toppers are made of memory foam.

This is because memory foam has superior body-contouring abilities, turning every average mattress into an orthopaedic-support base.

But, the downside is that memory foam retains heat. 🥵

This means that memory foam toppers often result in hot & clammy sleeping environments.

Temperature regulation scale

Of course, this is great if you easily feel cold at night or if it's in the middle of winter.

But if you're a heavier sweater or easily feel hot, then this hot sensation will be quite uncomfortable. 😩

The Simba topper has been designed as a cooling mattress topper to suit those who easily feel hot. ❄️

It features numerous temperature regulation properties:

  • The topper cover is breathable, allowing for a steady flow of air.
  • The side of the cover has a 3D mesh for extra airflow.
  • Latex has larger pores for enhanced breathability.
  • The spaces between the springs allow for natural ventilation channels, further enhancing airflow.

These three features enhance airflow throughout the topper, wicking away heat and moisture and keeping you cooler and more comfortable all night long.

That said:

You may find that you sleep hotter on mattress toppers than you would on just a mattress.

It's always a good idea to try out a topper - we'd recommend opting for toppers with risk-free trial periods.

Simba mattress topper cover

The Simba mattress topper cover is made of 1005 polyester.

It is soft and breathable to enhance the features of your mattress topper.

The cover is hypoallergenic, making it a great choice for people prone to allergies. 🤧

The top part of the cover is also removable and machine-washable at 40℃.

We would still recommend using a mattress protector, though, to safeguard both your mattress topper and the mattress underneath.

TOPPER: 40% OFF £300

Simba mattress topper cover

Conveniently, the Simba mattress topper cover features an anti-slip base layer on the bottom side and elasticated corner straps, which fit snugly around your mattress.

This means that your mattress topper stays firmly on top of your mattress.

Mattress toppers without straps, like many of the IKEA mattress toppers, tend to move around as you sleep.

This can be really uncomfortable.

Simba topper sizes

The Simba mattress topper is available in all the standard UK mattress sizes. 🇬🇧

These include:

  • Simba mattress topper single: 90 x 190 cm (3' x 6'3")
  • Simba mattress topper small double: 120 x 190 cm (4' x 6'3")
  • Simba mattress topper UK double: 135 x 190 cm (4'4" x 6'3")
  • Simba mattress topper UK king-size: 150 x 200 cm (5’ x 6’6”)
  • Simba mattress topper super king-size: 180 x 200 cm (6' x 6'6")

The wide range of sizes is convenient as it ensures you can get the topper for any size bed!

UK mattress sizes

Simba mattress topper depth

The Simba mattress topper has a depth of 7 cm (2.7 inches).

This is a good depth for toppers, above the industry standard of 5 cm (1.9 inches), ensuring that the topper really does change the way your mattress feels.

Did you know that deeper mattresses tend to look smart on any bed frame? Read our article on the best bed frames for some inspiration.

You do have to be careful, though, that your fitted sheets will fit over the depth of the topper and your mattress.

The Simba Performance fitted sheet is a good option and is available in all standard king, double mattress, and single sizes.

These are designed to fit over mattresses up to 40 cm deep (15.7 inches).

While you're kitting out your bedroom, you can also look at the Simba Performance bed linen set.

This includes a duvet cover and two pillowcases to complete your Simba look.

Simba mattress topper prices

The Simba mattress topper is an excellent product, but it is much more expensive than other mattress toppers on the market.

Silentnight mattress toppers, for example, are available at a mere fraction of the price. 😳

And comparable quality products, like the Eve mattress topper and the Panda mattress topper, are also much cheaper.

The premium price is primarily because of the hybrid nature of the topper.

Pocket sprung products are generally more expensive than all-foam products - except, of course, if you're opting for anything from Tempur!

Luckily, though, Simba offers frequent discounts and promotions - more on this below. 👇

Simba mattress topper discounts

Even though Simba products are on the higher end of the price range, the company does offer frequent discounts and promotions.

Most Simba discounts are available for the mattresses.

But, you'll also find "percentage-off" vouchers for purchases above a certain price range, which you can use for the Simba mattress accessories.

The price range usually sits at £300 or £350, and you can get up to 40% off! 🥳

Simba delivery conditions

Like most bed-in-a-box mattresses, the Simba mattress topper is delivered rolled up and boxed. 📦

Delivery is free of charge within the UK mainland and usually takes place within 1 - 3 working days.

You can also choose additional delivery services at an extra cost, include two-man delivery and next-day delivery.

The Simba mattress topper is much smaller and lighter than the actual mattress, so one person can easily handle it.

How do you unpack your Simba mattress topper?

Like the Simba mattress, the mattress topper is compressed.

Unboxing it is very simple:

  • Open the box on top of your mattress and roll out your mattress topper.
  • Cut off the plastic wrapping
  • Roll out the topper across your mattress.
  • Leave it to expand for at least 2 hours.

Your topper should be fully expanded in a maximum of 24 hours. ⏰

Does the Simba mattress topper come with a trial period?

The Simba mattress topper comes with a standard 14-day return policy.

But, Simba knows that it's important to try a mattress topper to see if it really suits you.

Normally, products returned within 14 days have to be unopened and unused.

Luckily, the Simba mattress topper comes with a 14-night trial.

This means you can actually test out the topper out at home to see if it works for you and your mattress.

TOPPER: 40% OFF £300

14 days isn't long.

Competitive products, like the Eve mattress topper, come with a 30-night trial period. 🗓

But 14 days is still plenty to see if you like a product - or hate it.

If you're not convinced, you can simply return the product and get a full refund. 💷

This makes the Simba Hybrid mattress topper a completely risk-free investment!

What if you need a new mattress?

Mattress toppers are great but they can't fix all of your mattress-related problems.

If you have an old mattress that's worn out or sagging, you will have to buy a brand new mattress.

We can highly recommend the following:

Is the Simba Hybrid mattress topper worth the money?

There's no denying that the Simba Hybrid topper is an excellent mattress topper.

But, it is quite a bit more expensive than other mattress toppers on the market.

If you have the budget, this is an excellent buy.

If not, we'd recommend you turn to comparable quality products that offer much better value for money, like the Panda mattress topper.

Frequently asked questions

  • Where is the Simba mattress topper made?

    All Simba mattress toppers are sourced and made in Europe.

    Mattress topper factories are based in the UK and in Poland.

  • Is the Simba topper environmentally-friendly?

    Like all Simba products, the foams used in the Simba mattress topper are guaranteed to be pro-planet and TCPP-free.

    Simba-Pure foam is a purer foam free from TCPP, phosphate, parabens, biocides, organic pollutants, and other chemicals. 

    It is also CertiPUR-certified.

  • Is the Simba topper a memory foam mattress topper?

    No, the Simba mattress topper is not a memory foam topper.

    Simba uses a combination of Aerocoil pocket springs, synthetic latex, and high-resilience foam to construct their mattress topper.

    Simba actually doesn't have many memory foam products, though you will find memory foam in the Simba Hybrid pillow.

  • Can I buy the Simba Hybrid mattress topper on Amazon?

    Yes, the Simba Hybrid mattress topper is available on Amazon in the UK.

    But, we always recommend buying directly from Simba Sleep.

    This guarantees you'll get the Simba quality and benefit from amazing discounts!

  • Can you put a mattress topper on a Simba mattress?

    Yes, you can indeed put a mattress topper on a Simba mattress.

    But you'd only really need one if the mattress is too firm for you.

    The Simba mattress topper is like a "small package" version of the Simba mattress.

    If you don't like the feel of the mattress, you probably won't like the feel of the topper either.

    That's why we always recommend using the 200-day risk-free trial period the Simba mattresses come with to decide if it's a good fit for you.

  • How do you store the Simba mattress topper?

    Conveniently, the elasticated corner straps serve a dual purpose.

    Not only do they keep the topper firmly on your mattress, but they also allow you to roll up the Simba topper and use the straps to fix it in place.

    This means transporting or storing the Simba mattress topper is very easy.
