What Our Customers Say
Ensuring You Sleep Undisturbed
Disturbed sleep means less energy during the day to all the things that matter to you. We have identified the most common causes of sleep disturbance and developed our mattresses to combat them.
Prevent Overheating While Sleeping
Overheating at night is one of the most common reasons for disturbed sleep. This is why we create many small perforations throughout the mattress layers (the AirFlow system), allowing fresh air to circulate throughout the mattress, removing excess heat and ensuring you stay cool, all night long.
Maximise Support & Spine Alignment
Springs are the king of support in a mattress. The Pure+ uses a total of up to 4000, encapsulated pocket springs split between 2 separate comfort layers. This creates the perfect spine alignment and support for your joints and back, ensuring you wake up pain-free and ready for the day ahead. Each sleeper is supported individually, preventing any sleep disturbance caused by the other’s movement.
4000 Pocket Sprung Mattress FAQs
-
Is a 4000 spring mattress good?
Yes, a 4000 spring mattress is generally considered high-quality. The high number of pocket springs provides excellent support and comfort, as each spring works independently to contour to your body and reduce pressure points. This can lead to a more restful and supportive sleep experience. We find this to be the maximum number of springs at which you can still feel the difference in comfort.
-
What is the highest number of pocket springs in a mattress?
The highest number of pocket springs in a mattress can exceed 5000, with some luxury models featuring even more. The more springs, the finer the level of support and contouring, though the difference becomes less noticeable at higher counts. It's important to balance spring count with other factors like mattress materials and construction.
-
Is 1000 pocket sprung better than 2000?
A 2000 pocket spring mattress generally offers better support and durability than a 1000 pocket spring model, as it provides more individual points of support. However, the best choice depends on personal preference and comfort needs, as well as factors like firmness and mattress materials.
-
What are the disadvantages of a pocket spring mattress?
While pocket spring mattresses offer great support and durability, they can be heavier and more expensive than other types. Additionally, they may not provide as much contouring as memory foam mattresses, which is why our hybrid mattresses combine the two materials, for the best of both worlds!

Frequently Asked Questions
How Firm Is The OTTY Pure+ Mattress?
The OTTY Pure+ scores 5.5/10 on our firmness scale, where 10 is firm. This makes it a medium mattress.
Do I Need To Rotate My Mattress?
Yes, you must rotate your mattress once a month for the first 12 months and then once every 3 months thereafter. See full terms here.
What Base Do I Need For My Mattress?
OTTY can be used with a variety of standard bed bases, such as divans, slatted frames, adjustable beds, or platform beds. We highly recommend slatted bases because they allow better airflow beneath the mattress.
However, we do not offer any guarantee using the mattress with steel bed frames and thin steel supports, as they may not offer the essential support needed for the mattress. This lack of support could potentially result in sagging over time.
See T&Cs for full terms.
I Sleep On My Side, Is This Mattress Right For Me?
The OTTY Pure+ has a total of 5cm of memory foam, fixed on top of the 4000 encalpsulated pocket springs, which allows your body to sink in a little and feel supported. We recommend the Pure+ for side and back sleepers.
CertiPUR/Europur Approved. FIRA Certified
All OTTY foam is CertiPUR and Europur approved, meaning that both the quality and toxicity of the foam have been tested time and time again and pass the highest standards set by the governing body.
FIRA is the UK’s designated testing house for BS7177 Fire Hazard testing which all furniture products must go through. All OTTY products are fully compliant with the UK fire regulations.
