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.
Comfort: Nectar vs Simba mattress
The Nectar and Simba Hybrid offer medium-firm support, low-motion isolation, and excellent spinal support and comfort. 🙌
But comfort is subjective.
That's why you need to consider your individual needs, which determine how comfortable you might feel on either mattress.
Both mattresses are great for side sleepers
The Nectar and Simba mattresses are designed to contour around the joints for immediate pressure relief, making them an excellent choice for those who sleep on their side.
The Nectar and Simba Hybrid can adapt around the joints in the side sleeping position, even for lighter sleepers who typically find it more difficult to sink into a standard mattress. ⚓
Take a look at the Nectar (pictured left) and the Simba (pictured right) below:
Both mattresses are rated medium-firm, making them the ideal firmness for side and back sleepers.
The Nectar Memory Foam mattress has a more solid feel, while the Simba Hybrid has a softer, springier surface.
Unfortunately, both mattresses are too soft for stomach sleepers who require a mattress with firm support.
Sleeping on a mattress that’s too soft prevents the spine from remaining in a neutral position and may cause back pain. 😖
We'd recommend a firmer hybrid option to stomach sleepers, such as the Origin Hybrid mattress.
The Simba Hybrid is the best at absorbing motion
Both mattresses provide a "hugged in" feeling that gently cushions pressure points and a supportive base that distributes weight evenly.
They also have excellent motion isolation. ✔️
This means you shouldn't feel your partner moving around on the other side of the bed while you sleep.
Both mattresses absorb motion exceptionally well, especially compared to standard coil mattresses.
However, the Simba Hybrid has the best motion isolation.
While the Nectar Memory Foam mattress is pretty good at absorbing motion, we still felt a little movement from our partner during the night. ⛵
The Nectar mattress is slightly firmer
The Nectar and Simba Hybrid are both considered medium-firm, which makes them particularly appropriate for side and back sleepers.
To determine firmness, we rank each mattress between 1 - 10, where 1 is the softest and 10 is the firmest.
However, we rated the Nectar mattress slightly firmer with a 7/10 rating compared to the Simba Hybrid, rated 6/10 on our Sleep Hero firmness scale. 👇
While the Nectar foams provide more solid support, the Simba Hybrid's pocket spring layer is more flexible than the firm base foam layer on the Nectar mattress.
This means the Simba Hybrid has slightly more give, which might be more comfortable for lighter-weight sleepers.
Yet, fans of a firmer-feeling mattress may find the Nectar mattress more suitable. 🧱
The Simba Hybrid has better edge support
Edge support is the stability and firmness at the very edge of the mattress.
Memory foam mattresses often fall short in this area because foam tends to sink and can even sag over time.
The Nectar mattress has average edge support.
This is not ideal for those who regularly sit on the end of their bed to get dressed or put on their slippers in the morning.
The perimeter of the mattress isn't solid enough for frequent sitting, and you may find that the end of the mattress dips when all your weight is concentrated in that area.
However, the Simba Hybrid fared much better in our edge support test. 👍
We had various testers sit on the edge of the mattress.
Each tester felt supported when sitting along the very edge of the Simba Hybrid.
The Simba Hybrid includes a new support core base and edge-to-edge springs designed to promote stability around the entire edge of the mattress.
The Simba Hybrid is more breathable
Memory foam is known for retaining heat, leading to a warmer sleep experience. 🥵
However, the Simba Hybrid mattress offers a slight advantage as it includes both Simbatex foam and springs, which allows for better airflow and temperature regulation.
The Simbatex foam in the Simba Hybrid also includes cooling graphite to help regulate body temperature. ❄️
Overall, the Simba Hybrid has the best breathability and would be the better option for hot sleepers.

Cover: Nectar vs Simba mattress
The Nectar mattress has a moisture-wicking top cover made of a Tencel and cotton mix, with grey mesh sides for better air circulation and a non-slip base to keep it in place.
The Nectar cover doesn't include handles, but the non-slip base is perfect for lift-up ottoman beds as it prevents the mattress from sliding. 🎿
The Simba mattress has a sleek design, with a 500g polyester cover that is hypoallergenic and has carrying handles for easy movement.
Both the Nectar and Simba covers are removable, but the Simba has the advantage of the top cover also being fully washable at 40°C.
This makes it a better choice for allergy sufferers who may benefit from a washable cover to remove bacteria and dust mites. 🦠

Warranty: Simba vs Nectar mattress
When it comes to mattress guarantees, both Simba and Nectar have a lot of promise.
However, Nectar's "Forever Warranty" offers more coverage. ✅
The Simba mattress comes with a 10-year guarantee, while the Nectar mattress has an unmatched "Forever Warranty".
For the first 10 years, the Simba and Nectar warranty work the same.
If a fault is found, these brands will replace or repair the mattress for free during the first 10 years of ownership.
After 10 years, Nectar will repair, re-cover, or replace the mattress or cover at their discretion, with a transportation cost of £65 each way.
After 10 years, Simba's mattress warranty expires, and any repairs or replacements needed will be your responsibility, and you'll have to cover the costs.
To ensure the longest lifespan for your mattress, pair either with a mattress protector.
A mattress protector prevents accidental damage and bacteria build-up over time.
So if you spill a drink on your mattress, you won't have to worry about your warranty becoming void. ☔
Nectar and Simba both offer waterproof mattress protectors:
