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.
Recommended UK mattress alternatives
Like the Casper mattress, the Leesa mattress is unfortunately no longer available in the UK.
Here, you'll find our favourite UK mattress alternatives. 👇
Leesa mattress composition
The Leesa mattress is a foam mattress made of three different types of foam:
- Avena foam
- Memory foam
- Sturdy base foam
The unique combination of these foams is what makes the Leesa mattress so special. 🏅
The firmer and cooler branded Avena foam is the ideal counterpart to the softer and warmer memory foam.
Leesa mattress layers
There are three layers in the Leesa mattress.
A top layer of Avena foam (5 cm)
Avena foam is a patented, durable material with a pleasant cooling effect. ❄️
The foam has a density of 50 kg/m³.
A middle layer of memory foam (5 cm)
The high-quality memory foam adapts optimally to the body's contours. 🤗
It also reduces pressure points and stores body heat, which is great for those cold winter nights.
The foam has a density of 45 kg/m³.
Base foam layer (15 cm)
The firmer base foam promotes stability and supports the upper comfort layers.
The foam has a density of 32 kg/m³.
What does sleeping on the Leesa mattress feel like?
The Leesa mattress is incredibly comfortable. 🥳
The first time you lie down on it, you can really feel how the foams adapt to your body.
But, even though the mattress adapts so well to the body, it is still firm and solid.
This makes the Leesa the ideal choice for people looking for a good, well-balanced mattress.
The memory foam distributes body weight and relieves pressure.
This is because the mattress only sinks in where it is stressed, and unnecessary pressure points are thus avoided.
Good choice for most sleepers
We recommend the Leesa for every sleeping position.
But it also provides sufficient sinkage, which is important for people who sleep on their side.
This allows the spine to remain optimally aligned.
That said, heavier-weight sleepers above 100 kg may find the Leesa mattress too soft and might be better off choosing a firmer model. 🧱
But for lighter-weight sleepers, the Leesa is absolutely perfect.
A good orthopaedic choice
Due to the unique mattress structure combining high-quality foams, the Leesa mattress adapts to the body in an ideal way.
This is also very helpful for people with high orthopaedic demands.
The Leesa mattress adapted perfectly to our trial sleeper.
The spine remained well supported and in a healthy position. 🦴
The mattress also allowed for sufficient sinkage in the shoulder area, as well as sufficient support in the lumbar region.
This optimal spinal alignment prevents a build-up of tension and back pain.
The Nectar mattress, which has a similar composition, also allows for optimal spinal alignment - and this mattress is available in the UK!
Is the Leesa suitable for couples?
The Leesa provides excellent motion isolation.
In our tests, the movement sensors showed that the mattress absorbs movement very well.
This means you won’t be disturbed if your partner tosses and turns at night.
The Leesa is thus an excellent mattress for couples.
Should you buy the Leesa mattress?
The Leesa mattress has all the characteristics of a very good mattress, which is why we highly recommend it.
But, it's no longer available in the UK, which is a pity.
We'd recommend you try out the Nectar mattress as the best available all-foam alternative.
