Simba Hybrid

The Simba Sleep Hybrid mattress is built with five layers of comfort combining conical springs and memory foam. The five layers are as follows:

Breathable Sleep Surface

The top layer is detachable and washable so you can keep your mattress feeling fresher for longer. It’s hypoallergenic and super soft to the touch.

Open Cell Foam Layer

This layer is designed to help keep you cool by regulating the temperature while providing an extra boost of comfort.

Titanium Aero-Coil Spring Comfort Layer

The conical springs in Simba Sleep mattresses cradle your body from head to toe, keeping you supported throughout your sleep. Their design also helps to minimise disturbance between couples when sleeping in the same bed. The Simba Hybrid has up to  2,500 of these 25 mm conical springs.

High-Definition Foam with Edge Support

The layer of foam moulds to your body, ensuring top-level comfort throughout the night, whichever position you like to sleep in.

Zoned Base

The final layer is a zoned base that provides pressure relieving support to your sleep in all the right places.

Simba Hybrid Pro

As for the Simba Hybrid Pro, you’ll find it is made up of the following 7 layers:

Breathable Sleep Surface

This sleep surface is not only breathable, but it is also soft and lusciously thicker than that found in the Simba Hybrid.

Natural Wool Layer

Not only is wool soft, but it also acts as a natural fire retardant. This layer is unique to the Hybrid Pro.

Open-Cell Foam Layer

You’ll find this layer in both the Hybrid as well as the Hybrid Pro.

Two Unique Patented Titanium Aerocoil Spring Layers

Unlike the Simba Hybrid, the Hybrid Pro contains two layers of 25 mm conical Aeorcoil springs. Based on size, this mattress model can contain up to 5,000 springs. They are individually pocketed to reduce motion transfer.

High Definition Foam with Edge Support

This layer is found in both the Hybrid and the Hybrid Pro. In addition to being supportive, the edge support prevents you from sinking too much if you sit on the edge of your bed.

Zoned Support Base

The zoned support base is designed to provide different pressure relief and support to different regions of the body.

All Simba Sleep mattresses have been built to ensure the highest level of comfort, no matter which position you like to sleep in. They achieve this through their use of 2,500 to 5,000 conical pocket springs along with responsive memory foam.  You’ll find that there is minimal motion transfer so you won’t risk disturbing your partner.

3 years later

I purchased my king size Simba mattress approx. 3 years ago. Initially it felt very comfortable and both my husband and i loved it. Now 3 years later it still feels very comfortable however i have terrible back ache when waking and theres a noticeable ridge that runs down the middle of the mattress. My pain is so sore that I'm going to my docs to rule out a physical problem and if it is the case that theres nothing wrong then I'll have to buy a new mattress which wont be a Simba

Questions & Answers

David Little

Just ordered a mattress and wondered if pillows come automatically or do I have to apply for them – thanks – David

Currently, SimbaSleep is offering a promotion with two free pillows if you enter the code available at the top of their website when you check out. You may want to reach out to the brand directly to see if you can still get the pillows. SimbaSleep offers several ways to contact them on their site, including email, WhatsApp, and Live Chat.
Helene Donohue

I would need a queen size mattress. Is your EU Queen the same size as a US size? Also, can you ship to US? Thanks!

Simba does not ship to the US at this time. You may want to check out the most recommended mattresses in the US, as this is strictly a UK mattress review site.

Is the 100-night sleep trial the same if I pay with financing?


Hi Simba, I have a painful lower back. I have a bed 150 x 180cm — NOT 190cm that does not fit I’ve tried it.
Any advice is very welcome. Thanks Xandra

Unfortunately, Simba does not offer a mattress that is 150 x 180 cm. This seems to be a very unusual size and none of the brands we've reviewed carry it. Did you purchase your bed in the UK?
Maya Chatterjee

Thank you for the info.
Do not understand the terms:
360° high-density foam border
Zoned base

The 360 degree high-density foam border means that the foam border goes completely around the mattress to provide better edge support, so you won't sink so much if you sit at the edge of the bed. The zoned base means that the bottom layer of the mattress is divided into special support zones to better support your body based on common high pressure areas. This will help you sleep more comfortably.

Please can you tell me if your mattress contains any form of metal when talking about springs?

The springs are made of titanium, which is a metal.

Hi do any of your mattresses cater for someone that has shoulder pain,lower back pain hip and knee pain,I have tried firmer mattresses for my back but find very painful for shoulders after about 2 minutes on my back pain is constant and find it very hard to sleep

As we're not healthcare providers, we cannot recommend a mattress to alleviate pain. Instead, you should speak with your physician to determine if a particular mattress firmness would be best for you. That being said, your sleep position can affect which mattress firmness is most comfortable for you. If you sleep on your side, more pressure is put on your hips so it's better to choose a soft or medium firmness mattress. If you're a combination sleeper (sleep in multiple positions -- side, back, stomach), a medium-firm mattress tends to be a good choice. Simba Sleep is a good choice for those seeing a medium-firm mattress. For a softer mattress, check out MattressOnline.
