Simba touts the most 5-star reviews of any UK mattress brand, but is it just because they’ve been on the market for decades longer? Since 2017, Nectar has proved a worthy challenge to the veteran sleep company and is quickly compiling its own lot of 5-star reviews.

But when both the Nectar mattress and the Simba Hybrid mattress continually receive rave reviews from customers and mattress review sites alike, choosing between them is all the tougher. So, to help you decide which mattress is best for you, we’ve provided a side-by-side mattress comparison of Nectar and Simba Hybrid. We’ll break down all the key points you need to consider when finding a mattress that fits your sleep needs.

Our Top Picks For May 2024


The fundamental difference between Nectar and Simba is that Nectar is a foam mattress and Simba offers two hybrid mattresses: the Hybrid and the Hybrid Pro. For the sake of this article, we’ll focus on the original Simba Hybrid here and not the Pro. Whereas the Nectar mattress is made of various foam layers, the Simba Hybrid mattress is composed of both foam and springs.

Both feature 5-layer construction and measure 25 centimetres high.


This hybrid mattress likewise consists of five layers: a breathable sleep surface, cooling comfort layer, supportive pocket springs, responsive memory foam, and a zoned base for targeted pressure relief.

This all-foam mattress includes five layers: an adaptive cooling mattress top, smart memory foam, pressure-relieving memory foam, a 7-zone foam support base, and a sturdy positioning base.

Both brands prioritise pressure relief and support for the spine and joints. They achieve this via a zoned approach. Of course, each brand has its own way of exacting this support method. Likewise, Simba and Nectar both aim to improve edge support using innovative mattress technology.


The Simba Hybrid mattress also uses support zones to cater to individual body parts, but that’s not all. Pocket springs cradle your body, while memory foam moulds to it without the feeling of sinking in.

Their 360-degree high-intensity foam border boosts edge support to make getting in and out of bed a breeze.

The 7-zone support layer caters to individual parts of the body to ensure that your body receives the attention it needs. For example, the Nectar mattress is softer at the shoulder-level to allow for optimal spinal alignment. Meanwhile, it provides sturdier support at hip-level to prevent lower pressure.

Heat Regulation & Breathability

One of the most important factors affecting your quality of sleep is body heat. As such, heat regulation is crucial to consider when choosing which mattress is best.

Simba and Nectar have each designed their mattresses to keep sleepers cool. Nectar focuses on improving the breathability of memory foam, while Simba has the benefit of an air-circulating coil layer.


Simba Sleep has come up with a proprietary open-cell foam layer that regulates body temperature. As a hybrid mattress, it also has the benefit of a spacious coil layer, which allows hot air to move through the mattress, away from sleepers.

Traditional memory foam traps body heat, insulating sleepers as they sink into it. To prevent overheating, Nectar has developed its own memory foam that’s 30 times more breathable than most. Its adaptive cooling layer also serves to wick away heat and evaporate moisture for a more comfortable night of sleep.

Motion Transfer

The Simba Hybrid mattress and Nectar mattress are both recommended for their ability to limit motion disturbance. This is an important feature for partners sharing a bed, especially if one or both are restless sleepers.


Simba’s pocket springs help localise any motion disturbance to prevent transfer to other parts of the mattress.

Among nearly all reviews, the Nectar mattress registers practically no motion transfer at all. Those who toss and turn in the night will love this mattress.


Both mattresses are about a 6 on the 1 to 10 firmness scale. Medium-firm mattresses like these are the most popular because they cater to all sleepers. Back sleepers, side sleepers, stomach sleepers, and combination sleepers will all feel comfortable.

Because both mattresses feature similar firmness ratings, customers should prioritise other factors in their mattress comparison. Focus on construction and support instead.

Ecological Impact

Unfortunately, mattresses have not always had the best environmental impact. Many old mattresses get thrown in landfills that are polluting the planet, while noxious off-gassing can pollute the home.

Thankfully, modern mattress brands like Nectar and Simba Sleep are actively working to change that.


Simba is also dedicated to the environment, using manufacturing practises that produce zero waste. All manufacturing by-products are recycled. They also refrain from using animal products and products tested on animals and are vegan-friendly.

Like Nectar, the Simba Hybrid mattress has CertiPUR certification for its foams.


Dedicated to the environment, Nectar has partnered with the organisation ClimatePartner to improve the manufacturing process. All Nectar mattresses are effectively carbon neutral.

The Nectar mattress is also CertiPUR-certified, meaning the foam is free of harsh chemicals and gasses.

Notable Features

To set themselves apart from the rest, both brands include features on their mattresses that you won’t find elsewhere. For example, both Simba and Nectar have created unique mattress covers. See what else they’ve included here:


Simba has also developed its own mattress cover that, unlike Nectar’s, is removable and washable. Their mattress cover is also hypoallergenic, so it’s an especially great choice for those who may struggle with allergens.

The Simba Hybrid mattress also has the added benefit of being sold in stores. You can find them at select locations of John Lewis and Partners and Bensons for Beds across the UK. The best way to test any mattress, however, is by ordering it and sleeping on it for at least a month.


Nectar developed a unique mattress cover that is adept at keeping sleepers cool throughout the night. It is also scientifically shown to be more breathable than cotton and better suited to circulating heat and air.


Just as Simba and Nectar are comparable in many fields like firmness and motion transfer, they are sold at a similar price point. Both mattresses are rather affordable. However, each brand has its own trial and guarantee periods.

The Simba Hybrid mattress comes with a 100-night trial and a 10-year warranty. Simba also offers free shipping.

The Simba UK Double-sized mattress costs £799.

Both brands offer frequent sales, so you can usually get their mattresses for less. For example, at the time of writing this article, the double-size Simba is on sale for £559.


The Nectar mattress comes with a 1-year trial period and a forever warranty. This is one of the most generous offers on the market, especially considering that each mattress purchase comes with two free premium pillows.

The Nectar UK Double-sized mattress costs £569.


Simba and Nectar are both superb mattress brands, but before you make a commitment to one, take time to consider all the factors. Good sleep is fundamental to good health, so this is a decision you should take seriously.

Both cater to all kinds of sleepers, so you should make your choice based on the features that matter most to you. If you prioritise low environmental impact, you might want to choose Nectar’s carbon-neutral mattress. If you sleep hot, you might prefer the air circulating coils of the Simba Hybrid mattress.
