wowttrelax Folding Double Mattress 6 Inch Review: An Honest Look at Comfort vs. Convenience

We’ve all been there. You get a text: “Can’t wait to see you this weekend!” Suddenly, the spare room, which doubles as a home office and a storage zone for things you can’t bear to part with, needs to transform into a comfortable guest suite. The dreaded air mattress comes to mind—the slow deflation, the noisy pump, the feeling of sleeping on a glorified pool float. Or perhaps it’s the annual family camping trip, where the thin roll-mat feels less like a bed and more like a cruel geological survey of every pebble and root beneath you. The problem is universal: we need a sleeping solution that is comfortable for our guests (or ourselves) but disappears without a trace when it’s not needed. Not solving this means subjecting loved ones to a terrible night’s sleep, which can sour a visit, or enduring back pain on an adventure, which ruins the experience. The search for a portable, storable, and genuinely comfortable mattress is a modern domestic quest.

What to Consider Before Buying a Folding Mattress

A folding mattress is more than just an item; it’s a key solution for versatile living, transforming any space into a potential sleeping area in seconds. Its primary benefits are its incredible space-saving design and its multi-functionality. Unlike a traditional mattress that demands a permanent bed frame and a dedicated room, a folding mattress offers the freedom to accommodate guests, create a comfortable camping setup, or even provide a plush floor seating area for movie nights, all while being easily stowed away in a cupboard or the boot of a car. It bridges the gap between the inconvenience of an air bed and the permanence of a full guest room, offering a tangible, supportive sleeping surface that’s ready at a moment’s notice.

The ideal customer for this type of product is someone facing spatial constraints or requiring a flexible sleeping arrangement. This includes apartment dwellers, families who frequently host guests, caravan owners, and avid campers. It’s a lifesaver for those who need a reliable guest bed but lack the space for a permanent one. However, it might not be suitable for those who need a primary mattress for nightly use over many years, or for individuals with severe orthopedic conditions who require a specialised, high-end support system. For daily sleeping, a traditional pocket sprung or hybrid mattress would be a more durable and supportive alternative. If portability isn’t a primary concern, investing in a permanent mattress is always the better long-term choice for sleep health.

Before investing, consider these crucial points in detail:

• Dimensions & Space: A UK standard double mattress is 135cm x 190cm. When unfolded, ensure you have this much floor space clear. Crucially, check the folded dimensions to confirm it will fit in your intended storage space, be it a wardrobe, under a bed, or in your vehicle. The thickness, in this case, 6 inches (15cm), is a vital factor for comfort—anything less can often lead to feeling the hard floor underneath.
• Firmness & Support: This is perhaps the most critical, and subjective, factor. Manufacturers use terms like “Medium Plush” or “Medium Firm.” A mattress that is too soft will cause you to sink, potentially leading to poor spinal alignment and back pain. One that is too firm can create pressure points on your hips and shoulders. For a temporary mattress, a medium firmness is often the safest bet to accommodate a variety of sleepers.
• Materials & Durability: The core material dictates the entire sleep experience. High-density foam provides foundational support, while memory foam is known for its slow-response, pressure-relieving contouring. A simple, low-density polyurethane foam will feel more “spongey” and offer less support. The quality of the outer cover is also important; a removable, washable, and breathable cover significantly enhances hygiene and longevity.
• Ease of Use & Maintenance: The primary appeal of a folding mattress is convenience. Look for integrated carrying handles, a lightweight design (around 13kg is manageable for most adults), and a simple folding mechanism. A non-slip bottom is a fantastic feature that prevents the mattress from sliding on hard floors. Long-term care is simplified immensely by a machine-washable cover, which is essential for a product that might be used in various environments, from a living room to a tent.

While the wowttrelax Folding Double Mattress 6 Inch presents itself as a compelling choice, its performance on key factors like support can be a deal-breaker for some. It’s always wise to see how it stacks up against the competition, especially for those with specific health concerns. For a broader look at models specifically designed to protect your back, we highly recommend checking out our complete, in-depth guide:

First Impressions: Unboxing the Promise of Convenience

The wowttrelax Folding Double Mattress 6 Inch arrived in a surprisingly compact, vacuum-sealed box. At 13kg, it was easy for one person to manage, a promising start for a product built on portability. Upon opening, the mattress began to decompress immediately. The manufacturer suggests 48-72 hours for full expansion, but echoing the sentiment of one user, we found it reached a usable state in a remarkably short time—within about 15 minutes, it looked nearly full-sized. The deep grey and white knitted cover felt soft and high-quality to the touch, and the inclusion of sturdy carrying handles sewn into the side was a thoughtful design choice. Unfolding it from its compact, four-section cube into a full double mattress was effortless. Our initial impression was of a well-designed, convenient product that seemed to perfectly address the challenge of temporary bedding. On paper, with claims of memory foam and orthopedic support, it positioned itself as a premium, comfortable solution. However, the true test would be in the sleeping, and that’s where our findings began to diverge from the marketing claims. You can see its full feature set and official description online.

Performance Under Pressure: A Deep Dive into the wowttrelax Mattress

A folding mattress has to master two contradictory disciplines: it must be substantial enough to provide a restorative night’s sleep, yet light and compact enough to be managed and stored easily. It’s a difficult balance to strike. We put the wowttrelax Folding Double Mattress 6 Inch through rigorous testing, using it as a guest bed for a long weekend, a floor sofa for movie nights, and a general lounging pad. While it excels in portability, our deep dive revealed significant shortcomings in its most fundamental role: providing comfortable sleep support.

The Great Foam Debate: A Closer Look at Comfort and Support

This is the heart of the matter and where our experience confirmed the concerns raised by other users. The product is described as having a 2-layer construction of “certified memory foam” and “bamboo charcoal high-density foam,” with a “Medium Plush” firmness. However, upon testing, these claims did not hold up. When we unzipped the cover to inspect the core, we found a single block of foam, differentiated only by two colours. There was no distinct top layer of memory foam. Genuine memory foam has a slow-response characteristic; when you press into it, it holds the impression for a few seconds before slowly returning to shape. This foam, however, was highly responsive and “spongey,” springing back instantly, which is typical of standard polyurethane foam.

This material difference has a profound impact on sleep quality. Instead of the contouring, pressure-relieving hug of memory foam, we experienced a distinct lack of support. When an average-sized adult lay down, they would sink deeply into the mattress, almost feeling the floor beneath them, especially at pressure points like the hips and shoulders. This aligns perfectly with feedback from one user who found it “too spongey and soft” and noted you “just sink straight down in it.” For us, this wasn’t “Medium Plush”; it was simply soft. After just one night, our tester reported feeling a slight stiffness in their lower back. This validates the experience of another user who developed back pain after six nights, concluding it’s only a solution if “you don’t want them to stay too long.” This fundamental discrepancy between the advertised material and the actual product is the mattress’s biggest failing. It’s a critical point to consider, and we advise prospective buyers to check the latest product details and user feedback to see if this has been addressed.

Portability Perfected: Unboxing, Storage, and Handling

While the foam was a letdown, we cannot fault the design when it comes to convenience. This is where the wowttrelax Folding Double Mattress 6 Inch truly shines. The 4-fold mechanism is brilliant. It transforms a 190x135cm mattress into a neat, manageable cube of roughly 67x135cm with a height of 60cm. This compact form is incredibly easy to store. We slid it into a standard wardrobe with room to spare, a feat impossible for a traditional mattress or even most tri-fold designs. The 13kg weight is well-distributed, and the built-in handles feel robust and securely stitched, making it easy to carry up and down stairs or out to the car.

The speed of deployment is another major victory. Going from stored cube to ready-to-use bed takes less than 30 seconds. There’s no pump to find, no waiting to inflate, and no complex frame to assemble. This immediacy makes it far superior to an air mattress for impromptu sleepovers. The non-slip bottom is also a genuinely useful feature. On our laminate flooring, the mattress stayed put, even with some tossing and turning. For anyone prioritizing ease of handling and minimal storage footprint above all else, this mattress delivers flawlessly. Its portability is, without a doubt, a feature that really sets it apart in the portable bed market.

A Jack of All Trades? Assessing Its Multi-Functional Use

The manufacturer promotes the mattress for various uses: camping, caravans, guest beds, and even as a makeshift sofa. We tested its viability in these different scenarios. When folded into its sofa position (by stacking two sections to form a backrest), it creates a low, comfortable floor seat. It’s perfect for kids’ playrooms, student dorms, or for casual lounging while watching a film or playing video games. The soft foam that fails for sleep support is actually quite pleasant for this kind of short-term, upright seating.

For camping or caravan use, its utility is conditional. The 6-inch thickness does an admirable job of insulating you from the cold, hard ground. However, the lack of support remains an issue. If placed on an already soft surface like grass or a carpeted caravan floor, it’s a decent upgrade from a sleeping bag. But on a hard, uneven pitch, you’re likely to feel every lump and bump through the soft foam. As a guest bed—its primary advertised function—it’s a mixed bag. For children or small adults who sleep soundly on any surface, it’s perfectly adequate for a night or two. But for the majority of adults, especially those with any sensitivity to mattress firmness, the lack of support will likely become an issue after the first night. It’s a temporary solution in the truest sense of the word. You can explore its potential uses and see visual examples on its product page.

What Other Users Are Saying

Synthesizing feedback from other buyers reveals a consistent and telling story. There’s an initial wave of enthusiasm centered on the product’s convenience and appearance. One user was thrilled, stating, “Wowww much better than expected! It was ready to use in 10 minutes! Extremely comfortable! So beautiful!” This captures the positive first impression that we also experienced—it unboxes well and looks great.

However, this initial positivity is often tempered by experiences after sleeping on the mattress. The core criticism, which we confirmed in our testing, is the discrepancy in the foam. Multiple users stated plainly, “Not memory foam,” and described the interior as “one piece of soft foam, just two different colours.” This leads directly to the primary complaint about performance: a lack of support. As one individual noted, “it’s too spongey and soft, needs to be firmer as you just sink straight down in it.” The most damning feedback comes from the user who suffered back pain after less than a week, a clear indicator that for some, this mattress is not suitable for multi-night use.

How Does the wowttrelax Compare to the Alternatives?

No product exists in a vacuum. To give the wowttrelax Folding Double Mattress 6 Inch proper context, it’s essential to see how it stacks up against other popular sleeping solutions, both direct competitors and different types of mattresses altogether.

1. Inofia Double Folding Mattress 15cm

The Inofia is the most direct competitor to the wowttrelax. It’s also a 15cm (6-inch) folding mattress, but it uses a tri-fold design instead of a four-fold. The key difference often highlighted in user feedback for the Inofia is the foam quality. It is generally regarded as being firmer and more supportive, with a top layer that feels more genuinely like memory foam. While it may not fold down into as compact a cube as the wowttrelax, it offers a better balance between portability and genuine sleep comfort. For buyers whose primary concern is providing a truly comfortable night’s sleep for guests, the Inofia is likely the superior choice, even if it’s slightly less convenient to store.

2. Silentnight Pocket Essentials 1000 Pocket Sprung Mattress Single

Comparing the wowttrelax to a traditional mattress like the Silentnight Pocket Essentials highlights the trade-offs. The Silentnight is a permanent, non-folding mattress designed for nightly use. Its pocket sprung system provides far superior, zoned support that adapts to body weight and prevents motion transfer. It is undoubtedly the healthier and more comfortable option for long-term sleeping. Of course, it has zero portability. This alternative is for someone who has decided against a temporary solution and has the space for a permanent guest bed. If you have a dedicated spare room, investing in a proper mattress like this is a much better choice than any folding option.

3. Vesgantti 3FT Single Pocket Sprung Pillow Top Mattress Medium

The Vesgantti represents a middle ground in the world of permanent mattresses, offering a hybrid design with pocket springs for support and a foam pillow top for plush comfort. Like the Silentnight, it’s not portable. However, it’s a great alternative for someone who has found the wowttrelax far too soft and is now looking for a permanent single bed solution. It offers the “best of both worlds”—the responsive support of springs with the cushioning comfort that the wowttrelax attempts, but fails, to deliver with its overly soft foam. It’s an excellent choice for a child’s room, a daybed, or a single guest bed where quality of sleep is the top priority.

The Final Verdict: Is the wowttrelax Folding Mattress Worth It?

After extensive testing, our verdict on the wowttrelax Folding Double Mattress 6 Inch is mixed, with a strong caveat. As a feat of design for convenience and portability, it is an outstanding product. Its 4-fold system, manageable weight, and quick setup make it one of the easiest temporary bedding solutions we’ve ever tested. The washable cover and non-slip bottom are excellent, practical features.

However, a mattress must first and foremost be comfortable and supportive, and this is where the wowttrelax falls significantly short. The foam used does not perform like memory foam and is far too soft to be described as “Medium Plush.” It fails to provide adequate support for most adults, leading to a “sinking” feeling and potential back pain. We can only recommend it for very specific, limited use cases: as a floor sofa for lounging, a play mat for children, or as a bed for very occasional, single-night stays for non-discerning guests. If you need a mattress for multi-night use, for adults, or for anyone who values supportive sleep, we strongly advise looking at firmer alternatives.
