The Otty Pure Hybrid Charcoal Bamboo is the UK brand’s bamboo and charcoal infused take on its core hybrid formula. It pairs a bamboo and charcoal memory foam comfort layer with up to 2000 encapsulated pocket springs, and it carries a medium-firm rating of 6.5 out of 10 on Otty’s own scale. The pitch is straightforward: a cooler, fresher, more breathable sleeping surface for people who tend to overheat, delivered with a 100 night trial and a 10 year guarantee. This page weighs what Otty actually publishes about the Pure Hybrid Charcoal Bamboo and sets out who it suits, who should look elsewhere, and how it compares with a Saatva alternative.

Who is the Otty Pure Hybrid Charcoal Bamboo for?
The Otty Pure Hybrid Charcoal Bamboo is built for sleepers who overheat at night and want a fresher, more breathable surface without giving up the support of a spring core. It suits back and combination sleepers who prefer a medium-firm feel, and it suits shoppers who value a clear, published trial and guarantee over a long list of unverified claims.
Otty positions the Pure as an enhancement to its Original hybrid, with bamboo and charcoal added for temperature regulation, pressure relief, spinal alignment, durability, breathability and antibacterial properties. That framing matters: this is a comfort-focused upgrade rather than a firmness overhaul. The medium-firm rating of 6.5 out of 10 sits in the middle of Otty’s range, below the Extra Firm at 9 out of 10 and above the Pure+ at 5.5 out of 10.
It is a good fit if you:
- Run warm at night and want a mattress with a published airflow design
- Prefer a medium-firm feel rather than a plush or an extra firm one
- Want a trial long enough to judge the mattress across seasons
- Like the idea of bamboo and charcoal infused foam in the comfort layer
- Need a UK-delivered mattress with 0% finance available
What is in the Otty Pure Hybrid Charcoal Bamboo?
The construction is a layered hybrid: an embroidered cover with 2cm of bamboo and charcoal infused memory foam, a charcoal and bamboo memory foam layer, high density reflex foam over the springs, up to 2000 encapsulated pocket springs at 16cm, and a high density base foam foundation. Otty describes the spring layer as its unrivalled spring size, chosen to maximise support while minimising motion transfer.
Here is how the published specification breaks down:
| Specification | Otty Pure Hybrid Charcoal Bamboo |
|---|---|
| Firmness | Medium-firm, 6.5 out of 10 |
| Spring count | Up to 2000 encapsulated pocket springs |
| Spring layer | 16cm encapsulated pocket springs |
| Comfort layer | 2cm bamboo and charcoal infused memory foam in the embroidered cover |
| Support foam | High density reflex foam and high density base foam |
| Cover | Thick knitted, heavy cover |
| Airflow | Unique AirFlow system with small perforations through the layers |
| Trial | Up to 100 nights |
| Guarantee | 10 years |
| Finance | 0% interest available |
| Price | From 499.99 pounds |
The layer order tells you where the feel comes from. The bamboo and charcoal memory foam sits at the top, so the first sensation is contouring comfort, followed by reflex foam that transitions you into the spring unit, then a dense base that Otty says ensures the mattress stands the test of time.
How does the airflow design work?
Otty’s AirFlow system is a set of small perforations made throughout the mattress layers, allowing fresh air to circulate and remove excess heat. Combined with the bamboo layer, which Otty describes as naturally breathable and moisture-wicking, the design targets overheating as the primary sleep disruptor rather than as a secondary feature.
This is the clearest reason to consider the Pure over a plain memory foam mattress. Standard memory foam can trap heat, and Otty’s answer is mechanical: perforate the layers so air can move, then pair that with a bamboo-derived cover and foam that wicks moisture. For sleepers who wake up hot, that combination addresses the problem at the material level rather than relying on a cooling gel gimmick.
It is worth noting what the airflow design does not change. It does not alter the medium-firm feel, and it does not add or remove springs. The cooling story sits alongside the comfort story rather than replacing it.
What does the 100 night trial actually cover?
Otty gives you up to 100 nights to decide, backed by a money back guarantee described as risk free. That is a full season of use, enough to judge the mattress in summer and winter, though it is shorter than the 365-night trial offered by Saatva. The 10 year guarantee covers the mattress against defects for a decade, and 0% interest finance lets you spread the cost.
Delivery is handled by Otty’s own courier team, described as premium delivery. Customer service hours are published: 9am to 4pm Monday to Wednesday, 9am to 2pm Thursday, 9am to 12pm Friday, closed at weekends and bank holidays, with email and phone options.

How does the Otty Pure compare with the rest of Otty’s range?
The Pure Hybrid Charcoal Bamboo sits between Otty’s budget and premium options. Below it, the Aura Hybrid starts from 349.99 pounds with up to 1000 encapsulated pocket springs and a medium-firm rating of 6 out of 10. Above it, the Pure+ Hybrid offers up to 4000 encapsulated pocket springs, the same bamboo and charcoal infused memory foam, a softer medium rating of 5.5 out of 10, and the AirFlow system, starting from 599.99 pounds.
Otty also sells firmer and more natural options. The Extra Firm Hybrid is flippable with two firm comfort ratings, up to 2000 encapsulated pocket springs, and a firmness of 9 out of 10, starting from 524.99 pounds. The Natural Origin uses natural cotton with up to 2000 encapsulated pocket springs at 8 out of 10, handmade in the UK from 839.99 pounds. The Natural Evolve uses wool, cashmere and silk with up to 4500 encapsulated pocket springs at 7 out of 10, from 939.99 pounds.
Within that lineup, the Pure is the choice for someone who wants the bamboo and charcoal treatment at the lowest entry price, without stepping up to the 4000-spring Pure+ or paying for the natural fibre models.
Who should not buy the Otty Pure Hybrid Charcoal Bamboo?
Skip the Pure if you need an extra firm surface, if you want a trial longer than 100 nights, or if you are shopping in the United States rather than the UK. The Extra Firm Hybrid at 9 out of 10 is Otty’s answer for firmness seekers, and the Pure’s 6.5 out of 10 will feel too giving for strict stomach sleepers who want a hard surface.
Couples who are highly sensitive to motion transfer should also weigh the spring count carefully. Otty says the 16cm encapsulated pocket springs minimise motion transfer, but the Pure uses up to 2000 springs rather than the 4000 in the Pure+ or the 4500 in the Natural Evolve. If partner disturbance is your main concern, the higher spring count models are the logical step up within Otty’s own range.
Finally, the 10 year guarantee, while solid, is shorter than the lifetime warranty Saatva offers on the Classic. If long-term coverage is your priority, that difference is decisive.
What does the Saatva Classic offer instead?
The Saatva Classic is an innerspring mattress with a 3 inch Euro pillow top, a dual-coil design of over 1000 recycled carbon steel coils in full size and up, triple-tempered for durability, and patented Lumbar Zone technology for spinal alignment. It comes in three comfort levels: Plush Soft at 3 out of 10, Luxury Firm at 5 to 7 out of 10, and Firm at 8 out of 10, and in two heights, 11.5 and 14.5 inches.
Where the Otty Pure gives you 100 nights and a 10 year guarantee, the Saatva Classic gives you a 365 night home trial and a lifetime warranty. Saatva also includes free white glove delivery with in room setup and free old mattress removal, and the foams are CertiPUR-US certified and GREENGUARD Gold certified, with endorsement from the American Chiropractic Association.
The tradeoff is price and geography. The Otty Pure starts from 499.99 pounds with 0% finance, while the Saatva Classic is priced in dollars and positioned as a premium purchase. For UK shoppers who want bamboo and charcoal infused foam and a lower entry price, Otty is the natural choice. For sleepers who want the longest trial, the strongest warranty, and a choice of three firmness levels, the Saatva Classic is the stronger proposition.
What does the World Sleep Almanac score say?
World Sleep Almanac score: 7.6/10 for the Otty Pure Hybrid Charcoal Bamboo. The score is editorial and is based on five criteria: price at equivalent size, trial and returns, warranty, materials and construction, and publicly available customer reviews.
- Price at equivalent size: strong. Starting from 499.99 pounds with 0% finance puts the Pure within reach of most shoppers, and under Otty’s own premium models.
- Trial and returns: good. Up to 100 nights with a money back guarantee is a full season, though shorter than the 365 nights Saatva offers.
- Warranty: good. A 10 year guarantee is solid for the price bracket, but it does not reach the lifetime coverage Saatva provides.
- Materials and construction: strong. Bamboo and charcoal infused memory foam, a 16cm encapsulated pocket spring unit, high density support and base foams, and a published AirFlow perforation design give the Pure a clear material story.
- Customer reviews: not weighed here. The score reflects the published specification and policies rather than a tally of review counts.
The method behind our scoring is simple: each criterion is rated on what the brand publishes, then averaged into a single figure. The result is an editorial judgement, not a laboratory test.

Frequently asked questions
How firm is the Otty Pure Hybrid Charcoal Bamboo?
Otty rates the Pure at medium-firm, 6.5 out of 10. That places it in the middle of Otty’s range, softer than the Extra Firm Hybrid at 9 out of 10 and firmer than the Pure+ at 5.5 out of 10. It suits back and combination sleepers who want support with some contouring, and it may feel too soft for dedicated stomach sleepers who prefer a hard surface.
Does the bamboo and charcoal foam actually keep you cool?
Otty designs the Pure for temperature regulation. The AirFlow system perforates the mattress layers so air can circulate and remove excess heat, while the bamboo layer is described as naturally breathable and moisture-wicking. The charcoal infusion is intended to help keep the sleeping environment feeling fresher. Together, these features target overheating as a primary sleep disruptor.
How long can I try the Otty Pure before deciding?
Otty gives you up to 100 nights to decide, with a money back guarantee described as risk free. That is enough time to judge the mattress across a season, though it is shorter than the 365 night trial Saatva offers on the Classic. The mattress also carries a 10 year guarantee.
Is the Otty Pure available outside the UK?
Otty’s published details, including prices in pounds, courier delivery, UK customer service hours and bank holiday closures, point to a UK focused operation. Shoppers outside the UK should confirm availability directly with Otty before ordering.
What is the difference between the Otty Pure and the Otty Pure+?
The Pure uses up to 2000 encapsulated pocket springs and is rated medium-firm at 6.5 out of 10, starting from 499.99 pounds. The Pure+ uses up to 4000 encapsulated pocket springs, carries the same bamboo and charcoal infused memory foam, is rated softer at medium 5.5 out of 10, and starts from 599.99 pounds. Both include the AirFlow system for temperature regulation.
Verdict
The Otty Pure Hybrid Charcoal Bamboo earns its place as Otty’s value entry into bamboo and charcoal comfort. Buy it if you overheat at night, want a medium-firm feel at 6.5 out of 10, and prefer a UK mattress starting from 499.99 pounds with 100 nights to decide. Look past it if you need an extra firm surface, want a trial longer than 100 nights, or want the lifetime warranty and 365 night trial that come with the Saatva Classic.
