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.
Otty mattress composition
The Otty Original Hybrid mattress is a 4-layer hybrid mattress that combines the unique properties of an innerspring mattress with a top layer of memory foam.
It contains 64% springs and 36% foam.
The 4 layers:
- Temperature-regulating memory foam
- High-density support foam
- 16 cm (6.2") pocket springs
- HD base foam
But what does all of this mean?
Temperature-regulating memory foam (3 cm / 1.18")
The first layer of the Otty Hybrid is a layer of memory foam with cooling properties.
The innovative Otty Hybrid Cool Blue Gel memory foam has been designed to enhance breathability, allowing for a cooler sleep. ❄️
The cooling gel foam also has additional pin holes for airflow.
This allows excess heat to flow out of the mattress and cool air to draw in.
High-density foam (3 cm / 1.18")
Specially designed Reflex Foam provides comfort, stability, and support.
This supportive sleeping surface prevents you from feeling the innerspring layer underneath.
Up to 2000 pocket springs
The Otty mattress relies on up to 2000 pocket springs (depending on the mattress’s size) to maximise support and minimise motion transfer. 🚣
The Otty Hybrid has 16 cm (6.2") full-size pocket springs instead of mini springs for a more quality experience.
This is also the prime reason for the mattress’s premium stability and medium-firm rating.
5 cm HD base foam
The base layer of the Otty mattress provides a solid foundation that enhances stability and gives the mattress its durability, enabling it to be enjoyed for a long time.
The base foam layer acts like the "bones" of the mattress, keeping everything stable and preventing sagging over time.
Side support panels
In addition to the mattress’s 4 layers, the Otty Hybrid also features airflow side support panels. 🌬️
These encourage enhanced temperature regulation and provide a more stable sleeping surface with edge-to-edge support.
How firm is the Otty mattress?
The Otty Original Hybrid mattress is the firmest in the Otty Sleep range. 🧱
This Otty firm mattress is on the firmer side at 7 out of 10 on the Sleep Hero firmness scale, where 1 is the softest and 10 is the firmest.
If you’re of a larger build, it might still feel a little too soft, but it’s much firmer than other hybrid mattresses and pure memory foam mattresses. 🧽
Heavier weight people feel more comfortable on pure innerspring mattresses as they are firmer than other mattresses and offer much more stability.
They’re also the preferred choice for stomach sleepers who need firmer support.
Otty Hybrid cover
The Otty Hybrid mattress features a luxurious, thick-knit mattress cover that provides a soft and comfortable sleeping surface.
A disadvantage is that the cover has no handles, which makes transporting and turning the mattress a little more complicated. 🤔
Can you wash the Otty mattress cover?
The Otty mattress cover is completely removable and can be machine-washed at 40 degrees.
This makes it a good choice for anyone who sweats at night and wants to keep their mattress fresh. 🧼
It’s also ideal for allergy sufferers, as regular washing of the cover helps remove dirt and dust accumulated on the cover.
Despite the washable cover, we recommend you use a mattress protector to keep your new Otty mattress safe from stains and accidents.
