How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.
Simba mattress topper composition
The Simba Hybrid topper aims to replicate the feel of the Simba mattress in a smaller package.
There are four layers to the Simba Hybrid topper.
These layers are:
- Super soft, breathable top cover
- Cooling open-cell Simba-Pure synthetic latex foam layer
- 2,500 Aerocoil 20 mm pocket springs enclosed in 100% polyester pockets
- High-resilience & high-density zoned Simba-Pure support base foam
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.
Does the Simba topper sleep hot?
Many of the best mattress toppers are made of memory foam.
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.
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.
To test this, we contrasted the Simba topper to the Panda memory foam topper.
Even though the Panda topper has cooling features, it still felt significantly warmer than the Simba topper.
If you're a heavier sweater or if you sleep hot, then going for a hybrid topper like the Simba is an excellent idea. 👌
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.

What does the Simba mattress topper weigh?
The Simba mattress topper can be quite bulky, depending on the size you go for, but it won't weigh more than 20 kg (44 lbs).
Here is a breakdown of the sizes and weights:
- Simba mattress topper single: 11.1 kg (24.5 lbs)

Luckily, mattress toppers won't have to be moved often as your mattress protector and bedding will stretch above the topper itself.
Simba mattress topper depth
The Simba Hybrid 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). 🥳
It also ensures that the topper really does change the way your mattress feels!
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 UK king, UK double, and UK 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 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! 🥳
We collect all of the best discounts on our discounts page.
If there are any Simba mattress topper discounts currently running, we'll also display them throughout this article.
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 essential to try a mattress topper to see if it suits you.
Usually, 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 at home to see if it works for you and your mattress.
Fourteen days isn't long.
Competitive products, like the Panda 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 return the product and get a full refund. 💷
This makes the Simba Hybrid mattress topper a completely risk-free investment!
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.
