wowttrelax Memory Foam Mattress Small Double Medium Firm Review: The Budget Bed-in-a-Box We Didn’t Expect to Love

For years, I felt like I was on a never-ending carousel of mattresses. I’d wake up with a familiar ache in my lower back, a stiffness in my neck, and the groggy feeling of a night spent tossing and turning rather than truly resting. Like many people, I’d tried everything: ultra-plush pillow-tops that felt like clouds for a month before sagging into hammocks, and traditional spring mattresses that eventually developed a knack for poking me in the ribs. One user review resonated deeply with my own journey, stating, “Having a back issue really makes you take note of where and what you are sleeping on.” This single sentence perfectly captures the frustrating and expensive cycle of trial and error. The truth is, a bad mattress doesn’t just ruin your night; it sabotages your day, impacting your energy, mood, and productivity. Finding a solution that offers genuine support without demanding a premium price felt like an impossible dream. This is the challenge that led us to test the wowttrelax Memory Foam Mattress Small Double Medium Firm, a contender in the bustling bed-in-a-box market promising restorative sleep on a realistic budget.

What to Consider Before Buying a Memory Foam Mattress

A mattress is more than just a piece of furniture; it’s a foundational investment in your health and well-being. It’s the key solution for achieving deep, restorative sleep, which is critical for physical recovery, mental clarity, and overall mood. A quality memory foam mattress, specifically, is engineered to solve the problem of pressure points. By contouring to your body’s unique shape, it distributes weight evenly, alleviating stress on the hips, shoulders, and spine. This leads to reduced tossing and turning, better spinal alignment, and a significant decrease in morning aches and pains. The main benefits are targeted support, excellent motion isolation (so you don’t feel your partner move), and a longer lifespan than many traditional spring mattresses.

The ideal customer for this type of product is someone facing persistent discomfort, back pain, or restless nights on their current mattress. It’s particularly well-suited for side sleepers who need cushioning for their shoulders and hips, and back sleepers who require firm but gentle spinal support. Couples also benefit greatly from the minimal motion transfer. However, a memory foam mattress might not be the best fit for everyone. Strict stomach sleepers often require an exceptionally firm surface to prevent their hips from sinking, and some individuals who tend to sleep very hot may prefer a hybrid or latex mattress with more airflow, despite modern gel-infused foams. For those who crave the significant bounce of a traditional innerspring, an all-foam construction might feel too “deadening.” In these cases, exploring hybrid mattresses could be a worthwhile alternative.

Before investing, consider these crucial points in detail:

• Dimensions & Space: The wowttrelax Memory Foam Mattress Small Double Medium Firm comes in a 4FT Small Double size (120x190cm). Before purchasing, measure your bed frame and your room meticulously. This size is perfect for single sleepers who want extra space, guest rooms, or couples in a more compact bedroom. Ensure you have enough room to walk around the bed comfortably. Also, consider the 20cm (approx. 8-inch) height and how it will sit within your bed frame and align with your bedside tables.
• Firmness & Support: This mattress is rated “Medium Firm,” which is often considered the universal sweet spot for comfort, accommodating a wide range of sleeping positions and body types. This rating aims to provide enough plushness to contour and relieve pressure points while being solid enough to keep your spine properly aligned. Your personal preference and body weight will play a role; heavier individuals may find a medium-firm mattress feels softer, while lighter individuals might perceive it as firmer.
• Materials & Durability: The wowttrelax features a two-layer foam construction: a 4cm gel memory foam comfort layer on top of a 16cm high-density support foam base. Gel-infused memory foam is a significant upgrade over traditional memory foam as it’s designed to dissipate heat more effectively, helping to regulate temperature throughout the night. The high-density base is crucial for preventing sagging and ensuring the mattress maintains its shape and supportive qualities for years to come.
• Ease of Use & Maintenance: As a “bed-in-a-box,” this mattress is compressed, rolled, and shipped directly to your door, making it much easier to manoeuvre through tight hallways and staircases. Once unboxed, it requires a period of 24-72 hours to fully expand. The cover material is listed as Polyvinyl Chloride or Vinyl with “Hand Wash Only” care instructions. We always recommend using a waterproof mattress protector to safeguard your investment from spills and stains, extending its lifespan significantly.

While the wowttrelax Memory Foam Mattress Small Double Medium Firm 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 wowttrelax: First Impressions and Key Features

The arrival of the wowttrelax Memory Foam Mattress Small Double Medium Firm was a familiar yet exciting experience. It arrived in a surprisingly manageable box, weighing just under 14kg. This immediately brought to mind one user’s comment about being initially worried by its lightness compared to other mattresses they had owned. We shared that brief moment of scepticism—could something this light offer serious support? Getting it to the bedroom was a breeze, a stark contrast to wrestling with rigid, traditional mattresses. Once we carefully cut away the plastic wrap, the mattress began to expand with a satisfying hiss. There was a faint, typical “new foam” scent, known as off-gassing, but it was minimal and dissipated completely within 24 hours in a well-ventilated room. The mattress has a simple, clean aesthetic with its grey and white tight-top cover. It feels soft and skin-friendly to the touch. We left it for the recommended 48 hours to reach its full potential before our first night’s sleep test.

Performance Deep Dive: Comfort, Support, and Real-World Use

A mattress’s true worth is only revealed after several nights of sleep. It’s about how your body feels when you wake up, day after day. We put the wowttrelax Memory Foam Mattress Small Double Medium Firm through its paces for several weeks, evaluating everything from its core support structure to how well it regulates temperature. Here’s our detailed breakdown of what you can expect.

The Two-Layer Foam System: A Breakdown of Comfort and Support

The heart of this mattress is its simple yet effective two-layer design. The top 4cm layer is gel-infused memory foam, and this is where the magic happens. As we lay down for the first time, we immediately felt this layer contouring to our body’s curves. There was no jarring firmness, but rather a slow, adaptive sinking feeling that cradled the shoulders and hips—the primary pressure points for side sleepers. This is precisely the kind of targeted relief that memory foam is famous for. One user, who had struggled with back issues and mattresses that were too soft, noted that this one “ticked both boxes…Firm not soft ✔️Flat surface to the top ✔️.” Our experience confirmed this sentiment entirely. The support isn’t aggressive or board-like; it’s deep and consistent.

Beneath this comfort layer lies the 16cm high-density foam base. This is the unsung hero of the mattress, providing the structural integrity and preventing that dreaded feeling of “bottoming out.” It acts as a stable foundation that keeps the spine in neutral alignment, which is critical for preventing and alleviating back pain. We found that whether sleeping on our backs or sides, our spines felt straight and supported throughout the night. The medium-firm rating felt accurate to us, landing at about a 6.5 out of 10 on the firmness scale. It provides the pressure-relieving hug of memory foam without the quicksand sensation some softer foam beds can have. This combination makes it a versatile choice that we believe will satisfy a wide range of sleepers looking for that perfect balance, a feature that really sets it apart in the budget category.

Breathability and Temperature Regulation

One of the historical complaints against memory foam has been its tendency to trap body heat. The “sleeping hot” phenomenon is a deal-breaker for many. Wowttrelax aims to combat this with its use of gel-infused memory foam and a breathable cover. During our testing period, which included some unseasonably warm nights, we were pleasantly surprised. The mattress did an admirable job of remaining temperature-neutral. We never experienced that clammy, overheated feeling that can disrupt sleep. While it doesn’t have the active cooling properties of high-end hybrid mattresses with extensive airflow channels, it performs significantly better than older, traditional memory foam models. One user highlighted the “breathable design” that “keeps temperatures regulated.” Our findings align perfectly with this. The gel infusion seems to work as intended, wicking away excess warmth from the body’s surface, allowing for a more comfortable and uninterrupted night’s sleep. For the vast majority of sleepers, the temperature regulation of this mattress will be more than sufficient.

Edge Support, Motion Isolation, and Durability

For anyone who shares a bed or uses the edge to get dressed in the morning, edge support and motion isolation are crucial. We tested the edge support by sitting directly on the side of the bed. Like most all-foam mattresses, there was a noticeable compression, but it wasn’t a precipitous drop. We never felt like we were about to slide off, which is a good sign for a bed in this price range. Getting in and out of bed was stable and easy.

Where the wowttrelax Memory Foam Mattress Small Double Medium Firm truly shines is in motion isolation. We placed a glass of water on one side of the bed and had another person get in and out on the other side. The water barely rippled. This is a massive benefit for couples, especially if one partner is a restless sleeper. You are highly unlikely to be disturbed by your partner’s movements during the night, a feature praised by users who noted its suitability for couples. In terms of durability, the high-density foam base is designed for longevity. While our test period was a matter of weeks, one user reported that after a year, their mattress had “maintained its shape and support.” This anecdotal evidence, combined with the quality of the foam we experienced, suggests that this mattress is built to provide consistent support well beyond its initial months of use.

The Unboxing Experience and Dimensional Accuracy

It’s important to address a recurring theme in user feedback: the final expanded height. The product is advertised as 20cm thick (approximately 8 inches). Several users noted that their mattress did not reach this full height, settling closer to 7 inches. In our own test, after 72 hours, our mattress measured just shy of the advertised 20cm, around 18.5-19cm. While this is a minor discrepancy, and one that did not impact the comfort or support in our experience, it is an inconsistency worth noting for buyers who have specific height requirements for their bed frame. Another minor point of feedback was that the cover’s grey and white pattern might differ from the one pictured online. Our review unit matched the description, but it’s a small detail to be aware of. Ultimately, these seem to be minor cosmetic or dimensional variations that, for most people, are overshadowed by the mattress’s excellent performance and outstanding value. For those seeking this level of comfort, it’s easy to see its full feature set and user reviews online.

What Other Users Are Saying

Sifting through customer feedback provides a clear and balanced picture of the wowttrelax Memory Foam Mattress Small Double Medium Firm. The overwhelming sentiment is positive, with most users expressing delight and even surprise at the quality delivered for such a reasonable price. Many echo the sentiment of one happy customer who said, “I’m so happy with this mattress, it’s just perfect! Very comfy and supportive… amazing for the price!” Another user, who was initially sceptical due to the mattress’s low price, was pleasantly proven wrong, stating it was “wonderfully soft and comfortable” and that the “foam seems to spread your body weight really evenly.” This praise for its comfort, support, and value is the most common thread.

However, the feedback isn’t without its criticisms, which lend authenticity to the overall picture. The most frequently mentioned issue is the dimensional discrepancy. As one “Not happy customer” pointed out with a photo, their mattress was “much less than 20 centimeters” even after two days. Another user confirmed this, measuring theirs at “7” rather than the 8” as advertised.” This appears to be the most significant and consistent drawback, alongside minor complaints about the cover’s appearance not perfectly matching the listing photos. These critiques, while valid, seem to be outweighed by the mattress’s core performance for the majority of buyers.

How Does the wowttrelax Compare to the Alternatives?

No product exists in a vacuum. To understand its true value, we must compare the wowttrelax Memory Foam Mattress Small Double Medium Firm to other options available. We’ve selected three distinct alternatives to see who might prefer a different path to a good night’s sleep.

1. Silentnight Pocket Essentials 1000 Mattress Single

The Silentnight Pocket Essentials 1000 offers a fundamentally different sleep experience. Instead of foam layers, it uses 1000 individual pocket springs, which provide a more traditional, bouncier feel. This might be preferable for those who dislike the “sinking” sensation of memory foam and enjoy a more responsive surface. As a pocket-sprung mattress, it will likely offer superior edge support compared to the all-foam wowttrelax. However, it is a single mattress, making it unsuitable for couples, and it won’t have the same contouring pressure relief or motion isolation that makes the wowttrelax so appealing for those with joint pain or restless partners.

2. BEDZONLINE 3ft Single Memory Foam Mattress Firm Orthopaedic

The BEDZONLINE mattress is a closer competitor, also being an all-foam design. The key differences lie in its firmness and thickness. At only 11cm thick and rated as “Firm” with an orthopaedic focus, this mattress is designed for those who need maximum, uncompromising support, often at the recommendation of a healthcare professional. It would be an excellent choice for strict back or stomach sleepers who must prevent their hips from sinking. In contrast, the wowttrelax’s 20cm height and medium-firm rating provide a much more balanced and plush feel, offering more cushioning and pressure relief, making it a better all-rounder, especially for side sleepers.

3. Direct Manufacturing King Mattress Storage Bag

This is not a mattress but an essential accessory that every mattress owner should consider. A heavy-duty storage bag is invaluable for moving house, redecorating, or storing a guest mattress when not in use. It protects your investment from dust, moisture, dirt, and damage. While the wowttrelax offers a great night’s sleep, this storage bag from Direct Manufacturing offers peace of mind and protection for the long term. It’s not an alternative to sleep on, but rather a complementary purchase to ensure any mattress, including the wowttrelax, remains in pristine condition for years.

Our Final Verdict: Is the wowttrelax Memory Foam Mattress Worth Your Money?

After extensive testing and careful consideration of user feedback, our verdict is a resounding yes. The wowttrelax Memory Foam Mattress Small Double Medium Firm delivers a level of comfort, support, and pressure relief that far exceeds its budget-friendly price tag. It successfully navigates the fine line of a medium-firm feel, providing a gentle contouring hug without sacrificing the essential support needed for proper spinal alignment. For those suffering from back pain, restless nights, or the disruptions of a fidgety partner, this mattress offers a genuinely effective and accessible solution.

Its primary weakness is the potential for a slight discrepancy in its fully expanded height, which for us, was a minor issue that didn’t detract from the superb sleep quality. If you are a first-time buyer, furnishing a guest room, or simply seeking to end your cycle of uncomfortable nights without emptying your wallet, this mattress represents outstanding value. It proves that a deep, restorative sleep doesn’t have to be a luxury. We wholeheartedly recommend it. If you’re ready to wake up feeling refreshed and pain-free, we suggest you check the latest price and discover the comfort for yourself.
