The OTTY Pure Hybrid Bamboo Mattress with Charcoal is a luxury hybrid mattress designed to offer a balanced blend of comfort, support, and natural freshness. This 25 cm deep mattress combines advanced memory foam technology with a robust pocket spring core. Its standout feature is the infusion of sustainable bamboo and activated charcoal into the memory foam, which aims to create a cleaner, cooler, and more hygienic sleep environment. With a medium-firm feel (rated around 6.5 out of 10 on the firmness scale), the Pure Hybrid Bamboo Mattress is engineered to suit a wide range of sleepers. From its cooling cover to its supportive base, every layer is crafted to enhance sleep quality. As an added bonus, OTTY backs this mattress with an excellent 100-night trial and a generous 10-year warranty. New customers can truly rest easy knowing their purchase is risk-free.
The Pure Hybrid Bamboo Mattress is built with several layers that each add to its comfort and durability:
Comfort Layers (Bamboo & Charcoal Foam): The top of the mattress features memory foam infused with bamboo and charcoal (including 2 cm integrated in the quilted cover). These layers provide instant cushioning and are naturally antibacterial and hypoallergenic. Bamboo boosts breathability and wicks moisture, while charcoal helps keep the surface fresh by reducing odours and excess moisture. When I ran my hand over the quilted top, it felt nicely padded and smooth, but you can still tell it's memory foam rather than a super springy top.Supportive Spring Core: Beneath the foam, a high-density support foam layer rests on top of up to 2,000 individually encased pocket springs (16 cm tall). This robust core adapts to your body's weight for targeted support and minimizes motion transfer. A sturdy base foam beneath the springs reinforces the whole structure and adds longevity, so the mattress retains its shape and support for years.Airflow Side Support: The mattress edges are encased with OTTY's unique Airflow side support. This gives you strong edge-to-edge support (no sagging if you sit or lie at the edge) and also allows air to circulate through the sides. The ventilation helps regulate temperature throughout the night and prevents that “overheated” feeling, keeping you cool and comfortable. That said, the reinforced edge can feel a touch firmer than the centre when you're right up against it. Firmness and Comfort The Pure Hybrid Bamboo Mattress is rated medium-firm (around 6.5 out of 10), which strikes a great balance between cushioning and support. There is enough plushness in the top foam layers to gently contour to your body, while the pocket spring core prevents you from sinking in too deeply. In other words, you'll feel comfortably cradled but still well-supported. This feel is neither overly soft nor overly firm, hitting a “just right” middle ground that many sleepers find comfortable. When I pressed my elbow into the top, it gave that slow memory foam hug, but it doesn't feel like you disappear into it.
Pressure Relief and Support The combination of contouring foam and responsive springs in this mattress provides excellent pressure relief without compromising support. The memory foam top layers cradle your body and cushion pressure points like shoulders and hips, reducing strain on joints. At the same time, the pocket springs distribute your weight evenly and supply adaptive support where you need it, helping to keep your spine in proper alignment. This dual action - cushioning up top and robust support underneath - can help minimize aches and pains, allowing you to wake up feeling more refreshed and free of stiffness. If you're a lighter side sleeper, you might find it a bit firm around the shoulder compared to a softer, deeper-foam hybrid.
Cooling and Breathability If you tend to sleep hot, the Pure Hybrid's design works in your favour. The bamboo-infused cover and charcoal-infused foam are there to help regulate temperature. Bamboo is naturally breathable and moisture-wicking, which means it helps dissipate heat and sweat. Charcoal further contributes by absorbing moisture and eliminating odours, keeping the mattress dry and fresh. On top of that, the mattress has a built-in Airflow ventilation system: the sides are ventilated and the pocket spring core allows air to circulate. Heat is less likely to build up around your body, so you can enjoy a cooler, more comfortable night's sleep. Still, it's got memory foam in the mix, so if you really run hot you may find it sleeps a bit warmer than a more latex-heavy hybrid.
Motion Control and Stability The Pure Hybrid is great at motion control, which is great news for couples. Thanks to the individually wrapped pocket springs and the absorbing effect of memory foam, movement on one side of the bed is less likely to disturb someone on the other side. If your partner tosses or gets up, the mattress isolates that motion very well. There is a bit of responsive bounce from the springs, but not enough to create significant shake or transfer across the mattress. Overall, you can expect a stable, undisturbed sleep even with two people sharing the bed.
Ideal User Types This mattress aims to cater to a broad range of sleepers, but a few groups in particular will enjoy what it offers:
Hot Sleepers: You'll appreciate the cooling design. The bamboo fabric and charcoal-infused foam help prevent overheating by wicking away moisture and allowing airflow, so you stay cooler at night.Allergy Sufferers: The natural bamboo and charcoal materials are hypoallergenic and resist dust mites and bacteria. This makes the mattress a good option if you have allergies, asthma, or sensitive skin, as it helps maintain a cleaner sleep environment.Couples: With excellent motion isolation, one partner's movements are less likely to wake the other. The medium-firm feel also hits a comfortable middle ground for different preferences.All Sleeping Positions: Whether you sleep on your side, back, or stomach, the medium-firm hybrid design provides a balance of cushioning and support to keep your spine aligned in any position.Those Needing Extra Support: If you have back pain or need extra support, the Pure Hybrid's sturdy core keeps your body in a neutral posture, which can help reduce aches and stiffness. Risk-Free Trial and Warranty OTTY's returns policy for the Pure Hybrid is a standout benefit. The mattress comes with a 100-night risk-free trial, allowing you to try it in the comfort of your home and return it for a full refund if it's not the perfect match (with no pickup fees or hassle). This generous no-risk trial gives new customers peace of mind when purchasing. The mattress is backed by a 10-year warranty, which means OTTY guarantees the materials and workmanship for a full decade. In short, you can be confident in the mattress's quality and have the security of getting your money back if it doesn't suit you. I also like that you get a proper amount of time to live with it, but 10 years is fairly standard for a hybrid at this price, so I wouldn't call the warranty a big step up.
