Vesgantti Single Memory Foam Mattress 18CM Review: The Ultimate Comfort on a Budget?

There’s a specific kind of dread that accompanies furnishing a guest room, a university dorm, or a child’s first “big kid” bed. It’s the challenge of finding a mattress that delivers genuine comfort and support without commanding a premium price tag. For years, I’ve navigated this exact problem, testing countless “budget” options that promised the world but delivered lumpy, unsupportive nights and a lingering sense of buyer’s remorse. The compromise always felt too great; either you paid a fortune for a well-known brand, or you settled for a thin, lifeless slab of foam that did more harm than good to your back. This search for the elusive sweet spot—where affordability, quality construction, and restorative sleep intersect—is what led us to the Vesgantti Single Memory Foam Mattress 18CM. Could this mattress-in-a-box finally be the answer for spare rooms and smaller spaces everywhere?

What to Consider Before Buying a Memory Foam Mattress

A mattress is more than just an item of furniture; it’s a key solution for achieving restorative sleep, which is fundamental to our overall health and well-being. A high-quality memory foam mattress, in particular, is engineered to solve several common sleep problems. It excels at pressure relief by contouring to the body’s unique shape, alleviating stress on joints like the hips, shoulders, and knees. This body-hugging property also leads to excellent motion isolation, meaning the movements of one person are far less likely to disturb a partner. Furthermore, modern memory foam mattresses often incorporate cooling technologies to combat the material’s old reputation for trapping heat, ensuring a more comfortable and regulated sleep temperature throughout the night.

The ideal customer for this type of product is someone facing the need for a comfortable, supportive sleeping surface in a compact space, such as a guest room, child’s bedroom, or student accommodation. It’s perfect for those who prioritise pressure relief and motion isolation and appreciate the convenience of a bed-in-a-box delivery. However, it might not be the best fit for everyone. Individuals who are significantly heavier may require a thicker, more robust mattress with zoned support or reinforced coils. Likewise, those who prefer the traditional, bouncy feel of an innerspring mattress might find the “sinking” sensation of memory foam less to their liking. For these users, a hybrid or a classic pocket sprung mattress could be a more suitable alternative.

Before investing, consider these crucial points in detail:

• Dimensions & Space: Always double-check the exact measurements of your bed frame against the mattress dimensions (90x190cm for a UK single). An 18cm thickness is relatively slim, making it an excellent choice for bunk beds or trundle beds where height clearance is a concern. Ensure it fits your space without being too tight or leaving large gaps.
• Firmness & Support: “Medium Firm” is a subjective term. This mattress is designed to offer a balance, but your personal preference, body weight, and primary sleeping position (side, back, stomach) will influence how it feels to you. Memory foam provides support by contouring, which differs significantly from the uplifting support of springs. We found it provided an excellent balance, a sentiment echoed by users who described it as “not too soft and not too hard.”
• Materials & Durability: The quality of the foam is paramount. The Vesgantti uses a combination of gel-infused memory foam and high-density support foam. Certifications like CertiPUR-US and OEKO-TEX STANDARD 100 are crucial indicators that the materials are free from harmful chemicals and are safe for your home, providing peace of mind alongside comfort.
• Ease of Use & Maintenance: The bed-in-a-box concept is incredibly convenient, but remember the initial 48-72 hour expansion period. A feature we particularly value is the removable, washable cover. This makes long-term hygiene and maintenance significantly easier, helping to prolong the life and freshness of your mattress.

While the Vesgantti Single Memory Foam Mattress 18CM 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 and First Impressions: The Ocean-Inspired Sleep Experience

The arrival of the Vesgantti Single Memory Foam Mattress 18CM is an event in itself. Like all modern bed-in-a-box mattresses, it arrives in a surprisingly compact, manageable package. Unboxing was straightforward: we simply positioned the rolled mattress on the bed base, carefully cut away the plastic wrapping, and watched it come to life. There was that satisfying hiss as the vacuum seal broke and the mattress began to rapidly expand. We did notice a faint “new mattress” smell upon opening, a common trait of vacuum-sealed foam products. However, as one user also noted, this odour dissipated completely within a day of airing out the room. Vesgantti recommends 48-72 hours for full expansion, but we found it reached about 95% of its 18cm height within the first few hours. The first thing that stands out is the unique “Ocean-Inspired” cover. The turquoise trim, wave-like stitching, and playful whale patterns give it a fresh, calming aesthetic that feels far more premium than its price point suggests.

A Deep Dive into the Vesgantti’s Performance and Features

After letting the mattress fully expand and airing it out, we put it through its paces over several weeks. We evaluated it based on the core pillars of a great mattress: comfort, support, temperature control, and overall usability. Our goal was to determine if its real-world performance lived up to its impressive list of features.

Comfort and Support: Striking the “Goldilocks” Medium-Firm Balance

The single most important aspect of any mattress is how it feels to sleep on, and this is where the Vesgantti Single Memory Foam Mattress 18CM truly shines for its category. The company describes it as “medium-firm,” and our testing confirmed this is an accurate and well-executed balance. The multi-layer foam construction is key to this success. The top layer consists of a gel-infused memory foam designed to contour to the body. As soon as you lie down, you feel it gently yield, cradling your shoulders and hips to alleviate pressure points. This is the classic memory foam “hug” that so many people love. We found this particularly beneficial for side sleepers, as it allowed for proper spinal alignment without creating pressure on the joints.

Crucially, this softness is underpinned by a much firmer, high-density foam base. This foundational layer prevents you from sinking too deeply into the mattress, providing the essential support needed to keep your spine in a neutral position. The result is a sleep surface that feels both plush and supportive. As one user aptly put it, “Lying on top you feel totally relaxed and every joint is supported yet the surface doesn’t seem to have moved.” This sensation of consistent, edge-to-edge support is remarkable for a mattress at this price. During our tests, we experienced no “bottoming out” and woke up feeling refreshed and free from the aches and pains that can come from a less supportive mattress. It’s this intelligent construction that makes it such a solid choice for those looking to find a budget-friendly mattress that still prioritises posture support.

Temperature Regulation: Beating the Heat with Cooling Gel and Breathable Mesh

One of the historical drawbacks of traditional memory foam has been its tendency to trap body heat, leading to an uncomfortably warm sleep environment. Vesgantti tackles this head-on with a two-pronged approach. First, the top comfort layer is infused with cooling gel particles. These particles are engineered to absorb and dissipate heat away from the body, helping to maintain a more neutral temperature throughout the night. While it won’t feel actively “cold” to the touch like some high-end cooling systems, we noticed a significant difference compared to older, basic foam mattresses. There was a distinct lack of that “sleeping in an oven” feeling that can plague dense foam.

The second, and perhaps more impactful, feature is the 3D breathable mesh fabric that runs along the entire border of the mattress. This is a design element often found on more expensive models. This highly porous material acts as a ventilation system, allowing air to flow freely in and out of the mattress core. This constant airflow helps to carry away the heat absorbed by the gel foam, preventing it from building up. During our testing, even on warmer nights, the mattress remained comfortably cool and breathable. This effective temperature regulation is a standout feature that elevates the Vesgantti Single Memory Foam Mattress 18CM above many of its competitors, making it a viable option even for those who typically sleep hot.

Design, Durability, and Everyday Practicality

Beyond the core performance metrics, the thoughtful design details of the Vesgantti contribute significantly to its overall value. The “Ocean-Inspired” cover isn’t just for looks; it’s made from a soft yet durable polyester fabric that feels pleasant against the skin. More importantly, it features a high-quality zipper that allows you to remove the entire cover for machine washing. This is a huge advantage for long-term hygiene, especially if the mattress is for a child’s room or a guest bed that sees infrequent but varied use. Keeping your sleep environment fresh and clean is effortless.

We were also impressed by the brand’s commitment to safety and quality, as evidenced by its CertiPUR-US and OEKO-TEX STANDARD 100 certifications. These independent verifications guarantee the foam is made without ozone depleters, heavy metals, formaldehyde, or other harmful chemicals, ensuring it’s safe for every member of the family. The mattress also performs well in motion isolation. While less critical for a single mattress, it speaks to the quality of the foam; placing a glass of water on one side and pressing down on the other resulted in minimal disturbance. The only practical design flaw we and other users identified is the lack of handles on the sides. At 11.35 kg, it’s not overly heavy, but the absence of handles makes rotating it or moving it for cleaning a bit more cumbersome than it needs to be. Despite this minor inconvenience, the overall build quality and practical features are exceptional for a mattress that offers such great value.

What Other Users Are Saying

Our positive experience with the Vesgantti is strongly reflected in the broader user feedback. The overwhelming consensus is one of surprise and satisfaction, particularly concerning the mattress’s comfort-to-cost ratio. Many users highlight that it hits the “perfect” medium-firm level, making it a versatile choice for guest rooms and children. One happy customer summarized this sentiment perfectly, stating, “If you’re looking for a comfortable budget single foam mattress, this is a solid choice. It’s not luxury tier but for the price, it offers excellent comfort and support.”

Praise is also frequently directed at the convenience of the delivery and the quick expansion process. The quality of the materials and construction is another common theme, with one reviewer noting, “This is an extremely good quality mattress, supportive, and comfortable… The materials used are really good.” The minor criticisms we found are consistent with our own findings. The most common complaint is the lack of side handles, which multiple users found made moving the mattress “a bit tricky.” A few also mentioned the initial off-gassing smell, though all agreed it faded quickly.

How Does the Vesgantti Compare to the Alternatives?

While the Vesgantti Single Memory Foam Mattress 18CM excels in its niche, it’s important to understand how it stacks up against other products that serve different, or adjacent, needs. Here’s a look at three notable alternatives.

1. Inofia Double Folding Mattress 15cm

The Inofia Folding Mattress serves a completely different purpose. Where the Vesgantti is a permanent sleep solution, the Inofia is all about portability and temporary use. Its tri-fold design makes it incredibly easy to store in a closet or transport in a car, making it the perfect choice for camping trips, sleepovers, or accommodating unexpected guests when you don’t have a dedicated guest room. While its 15cm foam construction is comfortable for short-term use, it lacks the sophisticated multi-layer support and cooling technology of the Vesgantti. If you need a versatile, storable sleep surface for occasional use, the Inofia is superior; for a permanent bed, the Vesgantti is the clear winner.

2. Direct Manufacturing King Mattress Storage Bag

This product isn’t a mattress at all but rather a crucial accessory for one. This heavy-duty storage bag is designed to protect a mattress from dust, moisture, and pests during a move or while in storage. It addresses a key logistical challenge that mattress owners face. For someone purchasing the Vesgantti for a university dorm, this bag would be an invaluable companion for moving in and out each year. It’s a complementary product, not a competitor. If you anticipate moving or storing your mattress at any point, investing in a high-quality bag like this is a very wise decision to protect your investment.

3. Silentnight Pocket Essentials 1000 Single Mattress

The Silentnight Pocket Essentials 1000 is a direct competitor but offers a fundamentally different sleep technology. Instead of an all-foam construction, it uses 1000 individual pocket springs as its core support system. This creates a bouncier, more responsive feel with more “push-back” support compared to the contouring “hug” of the Vesgantti’s memory foam. Those who dislike the sinking feeling of memory foam or prefer a more traditional mattress feel will likely prefer the Silentnight. However, the Vesgantti generally offers superior motion isolation and pressure-point relief due to the nature of its foam layers. The choice between these two comes down to a personal preference for springs versus foam.

Our Final Verdict: Is the Vesgantti Single Memory Foam Mattress 18CM Worth It?

After extensive testing and analysis, we can confidently say that the Vesgantti Single Memory Foam Mattress 18CM represents exceptional value and is a standout performer in the budget mattress category. It successfully avoids the common pitfalls of cheap foam mattresses, delivering a genuinely comfortable, supportive, and cool sleeping experience that far exceeds its price point. The balanced medium-firm feel makes it a versatile choice for a wide range of sleepers, while thoughtful features like the cooling technologies and washable cover add a layer of practicality often reserved for more expensive models.

While the lack of side handles is a minor annoyance and its 18cm profile may not suit heavier individuals, these are small trade-offs for the immense quality and comfort on offer. We wholeheartedly recommend it for anyone needing a high-quality single mattress for a guest room, a child’s bed, a student flat, or any space where you need maximum comfort without a maximum budget. If you’re looking for a mattress that proves you don’t have to spend a fortune for a great night’s sleep, your search may very well be over.
