Resspry King Size 12 Inch Memory Foam Hybrid Mattress Review: The Verdict on Cloud-Like Comfort and Support

For years, my partner and I were locked in a nightly battle. Not with each other, but with our old, lifeless mattress. It was a classic tale of tossing, turning, and waking up with more aches than we went to bed with. I’m a side sleeper who needs pressure relief for my shoulders and hips, while my partner sleeps on their back and needs solid lumbar support. Our old mattress failed us on both counts, creating a nightly compromise where neither of us truly won. We’d wake up feeling groggy, irritable, and as if we’d run a marathon in our sleep. We knew a change was essential, not just for our comfort, but for our overall health and well-being. This frustrating experience sent us on a deep dive into the world of modern mattresses, searching for a single solution that could end our sleep civil war. That’s when we discovered the promise of hybrid technology.

What to Consider Before Investing in a Hybrid Mattress

A hybrid mattress is more than just a place to sleep; it’s a sophisticated piece of sleep engineering designed to solve the fundamental conflict between softness and support. By combining layers of contouring memory foam with a core of responsive, individually pocketed springs, these mattresses aim to deliver the best of both worlds. They provide the pressure-relieving, body-hugging comfort that memory foam is famous for, while the springs offer the durable support, bounce, and breathability of a traditional innerspring mattress. This combination directly addresses common sleep problems like back pain, overheating, and partner disturbance, making it a powerful solution for a wide range of sleepers.

The ideal customer for this type of product is someone struggling to find that “just right” feeling. If you’re a couple with different sleep preferences, a sleeper who experiences aches and pains, or someone who tends to sleep hot on all-foam beds, a hybrid is likely an excellent choice. However, it might not be the perfect fit for those who crave the extreme, sinking softness of a pure memory foam mattress or the unyielding firmness of a traditional orthopaedic bed. For those seeking maximum portability for guest rooms or temporary use, a folding mattress might be a more practical alternative. For us, the promise of balanced comfort and targeted support made a hybrid the only logical path forward.

Before investing, consider these crucial points in detail:

• Dimensions & Space: Always double-check your bed frame’s measurements. The Resspry King Size 12 Inch Memory Foam Hybrid Mattress measures 200 x 150 cm, the standard for a UK King. Its substantial 30cm (12-inch) height also adds a luxurious, premium profile to the bed, so ensure your fitted sheets have deep enough pockets to accommodate it.
• Firmness & Support: “Medium-firm” is the most universally comfortable level, but it’s still subjective. The key differentiator here is the 9-zone support system, which provides varied firmness across the mattress to ergonomically support your head, shoulders, back, hips, and legs. This is a significant step up from single-firmness mattresses.
• Materials & Durability: A hybrid’s quality lies in its layers. Look for high-density foams, cooling gel infusions, and durable pocketed coils. Certifications like CertiPUR-US (for foam safety and performance) and Oeko-Tex (for textile safety) are crucial indicators of a well-made, non-toxic product, both of which this mattress holds.
• Trial Period & Warranty: A “bed-in-a-box” can feel like a leap of faith. A generous home trial, like the 100-night period offered by Resspry, is non-negotiable. It gives you ample time to let your body adjust and truly decide if the mattress is right for you. A long-term warranty (10 years in this case) signals the manufacturer’s confidence in its product’s longevity.

Choosing a mattress is a major decision, and it’s important to be fully informed. This review will break down every aspect of our experience, from unboxing to long-term sleep quality.

While the Resspry King Size 12 Inch Memory Foam Hybrid Mattress is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

Unboxing the Resspry: From Compact Box to Sleep Sanctuary

The arrival of the Resspry King Size 12 Inch Memory Foam Hybrid Mattress was, frankly, an event. We were expecting a massive, unwieldy slab, but instead, a surprisingly manageable box landed on our doorstep. The magic of vacuum-sealing technology is something to behold. With the help of the included cutting tool—a thoughtful touch that prevents accidental damage to the fabric—we carefully sliced through the plastic wrap. The mattress unfurled with a satisfying hiss, immediately beginning its transformation. We were initially sceptical, as many users are, when seeing it compressed. One reviewer noted they were “a bit concerned about thickness when it was vacuum packed,” a sentiment we shared. However, our concerns vanished as it rapidly expanded, reaching close to its full 12-inch glory within minutes. We followed the advice to let it breathe for about 48 hours to fully decompress and air out. While we noticed a faint “new product” smell, it was minimal and completely gone by the second day, a positive sign confirmed by others who found it “odor-free.” The first impression was one of substance and quality; the quilted Euro top felt plush and inviting, and the overall construction looked and felt far more premium than its price tag would suggest. You can check the latest price and trial information to see the value for yourself.

A Detailed Analysis of the Resspry’s Sleep Performance

After letting the mattress fully expand and acclimate, we spent several weeks putting it through its paces. We evaluated it on everything from initial comfort and support to how it handled motion transfer and temperature regulation. Here is our in-depth breakdown of the features that define the sleep experience on the Resspry King Size 12 Inch Memory Foam Hybrid Mattress.

The 9-Zone Support System: A Tailored Approach to Comfort

The flagship feature of this mattress is its 9-zone personalized support system, and I can confirm it’s not just marketing jargon. This is where the mattress truly shines. The design intelligently divides the mattress into nine distinct sections, each with a slightly different level of firmness delivered by the pocketed coils beneath the foam. The central third of the mattress, where your torso and hips lie, is noticeably firmer, providing crucial lumbar support and preventing your spine from sagging out of alignment. Conversely, the zones under the shoulders and knees are slightly softer, allowing them to sink in just enough to relieve pressure points. As a side sleeper, this was a revelation. I no longer woke up with a sore shoulder. The mattress contoured perfectly around my body’s curves, a feeling one user perfectly described as the mattress conforming “to the body so well that the body fits snug and feels well supported.” My back-sleeping partner also reported immediate benefits, feeling the mattress rise to meet and support the natural curve of their lower back. This targeted support is a feature often found in mattresses costing two or three times as much, and it’s a testament to the sophisticated engineering you can explore in its unique 9-zone support system.

Hybrid Harmony: The Perfect Marriage of Foam and Springs

The Resspry achieves a beautiful synergy between its foam and spring layers. The experience begins with the plush Euro top, a quilted layer that provides an immediate sense of luxurious softness. It feels, as one happy customer put it, “like a cloud.” Beneath this lies the gel-infused memory foam. This layer is responsible for the contouring and pressure relief, adapting to your unique shape to distribute weight evenly. Critically, the gel infusion works in concert with the pocket coil system to combat heat retention. The space between the individual coils allows air to circulate freely, wicking away heat and moisture. We tested this during a surprisingly warm week and never once felt like we were overheating—a common complaint with traditional memory foam. This was echoed by a reviewer who noted the mattress “must be really breathable as it doesn’t cause overheating.” Below the foam, the pocketed coil core provides the responsive, foundational support. This springiness gives the mattress a subtle bounce, making it easy to change positions without feeling “stuck” in the foam. It truly is the perfect balance: the initial hug of foam followed by the deep, resilient support of the springs. You can see the full specifications for yourself to appreciate the multi-layer construction.

Motion Isolation and Edge Support: A Game-Changer for Couples

For anyone who shares a bed, motion isolation is paramount. The individual pocketing of the coils is the key here; because each spring responds independently, movement on one side of the bed does not ripple across to the other. We put this to the test rigorously. My partner could get out of bed in the morning without me feeling so much as a tremor. It was remarkable. One user review captured this perfectly, stating, “It stays steady when you move and helps you sleep peacefully.” This feature alone has dramatically improved our sleep quality, ending the days of being woken up by a restless partner. Equally impressive is the edge-to-edge support. The perimeter of the mattress is reinforced with thicker coils, preventing the common issue of sagging edges. I could sit comfortably on the side of the bed to tie my shoes without feeling like I was going to slide off. This small detail has a big impact, as it makes the entire surface of the mattress usable, giving you more room to spread out. For a king-size bed, maximizing that real estate is a feature that significantly enhances sleep quality and perceived space.

What Other Users Are Saying

Across the board, the sentiment from other users is overwhelmingly positive and closely mirrors our own findings. Many, like us, were initially drawn in by the promise of a hybrid design at an accessible price point and were left “absolutely thrilled” with the quality and comfort. The ease of unboxing is a frequent point of praise, with one person noting that “Unpacking was completely effortless and took just a few minutes.”

The most consistent theme, however, is the transformative effect on sleep quality, particularly for those with back pain. One powerful testimonial comes from a user who found it “firm enough to support my painful back after multiple failed back surgeries.” Another simply stated, “This has to be the best mattress I have ever slept on… woke up refreshed in the morning back not aching.” While praise is widespread, the few minor critiques tend to focus on two things: the weight of the mattress, which one reviewer described as “pretty heavy,” making it a two-person job to set up, and the initial off-gassing smell. However, the same users almost always follow up by saying the smell dissipates completely within a day or two, confirming our own experience.

How the Resspry Mattress Compares to the Competition

While the Resspry King Size 12 Inch Memory Foam Hybrid Mattress is a formidable contender, it’s important to understand the landscape. Here’s how it stacks up against some other popular options, each catering to a slightly different need.

1. Silentnight Pocket Essentials 1000 Mattress Single

The Silentnight Pocket Essentials 1000 is a classic pocket sprung mattress from one of the UK’s most established brands. It focuses purely on its 1000-spring support system without the addition of memory foam layers. This makes it a great choice for traditionalists who prefer a bouncier, more responsive feel and may not enjoy the “sinking” sensation of memory foam. While it provides solid medium support, it lacks the advanced 9-zone targeting and the pressure-relieving contouring of the Resspry. Someone loyal to the Silentnight brand or who actively dislikes memory foam might prefer this, but the Resspry offers a more technologically advanced and nuanced support system for a similar price point.

2. Inofia Double Folding Mattress 15cm

The Inofia Folding Mattress occupies a completely different niche. Its primary selling point is portability and convenience. At 15cm, it’s half the thickness of the Resspry and designed to be folded up and stored away, making it an excellent solution for guest rooms, camping, or temporary living situations. While it does incorporate memory foam for comfort, it cannot compete with the deep, permanent support structure of a 12-inch hybrid like the Resspry. This is not a mattress for your primary bed; it’s a high-quality temporary solution. If space-saving and versatility are your top priorities, the Inofia is the clear winner, but for everyday luxury and support, the Resspry is in another league.

3. BEDZONLINE Single Memory Foam Mattress Orthopaedic

The BEDZONLINE mattress represents the all-foam alternative. It is marketed as a firm, orthopaedic mattress, designed specifically for those who need maximum, unyielding support. It uses layers of firm Reflex foam and memory foam to create a very solid sleeping surface. This is a great option for stomach sleepers or individuals who have been medically advised to sleep on a firm surface. However, it lacks the bounce, breathability, and targeted pressure relief of the Resspry’s hybrid design. The Resspry’s medium-firm feel offers a much better balance for side and back sleepers who need support without sacrificing cushioning comfort. If you need true orthopaedic firmness, BEDZONLINE is the choice; if you need balanced, adaptive support, the Resspry is superior.

Our Final Verdict: Is the Resspry Hybrid Mattress Your Ticket to Better Sleep?

After weeks of extensive testing, we can say with confidence that the Resspry King Size 12 Inch Memory Foam Hybrid Mattress is an outstanding product that delivers on every one of its promises. It strikes an exceptional balance between the plush, pressure-relieving comfort of memory foam and the robust, responsive support of a pocketed coil system. The 9-zone support is a genuinely effective feature that provides tailored comfort for all sleeping positions, making it a fantastic choice for couples with different needs. Add in the excellent motion isolation, sturdy edge support, and breathable construction, and you have a mattress that performs well above its price class.

We wholeheartedly recommend this mattress to anyone seeking a high-quality, medium-firm hybrid without breaking the bank. It is especially well-suited for side and back sleepers, couples, and individuals who suffer from common aches and pains. It has transformed our sleep, ending our nightly battles and leaving us feeling refreshed and supported every morning. If you’re ready to upgrade your sleep experience and invest in your well-being, we believe you will be just as impressed as we were. You can confirm its availability and current offers and take the first step towards a better night’s rest.
