What our reviewers found

Pros

  • Thanks to its firm tension and orthopaedic support, this mattress highly caters for back sleepers and those with special alignment needs, providing an enhanced sleeping comfort.
  • The integration of 1200 pocket springs provides a dynamic response to body weight, ensuring optimal pressure relief and minimised motion transfer for unwavering night-long comfort.
  • Comprising sumptuous layers of high density foam and a cosy knitted fabric cover, the mattress achieves a fine balance of firmness and breathability, promoting unbroken, blissful slumbers.
  • Drawing on the design qualities of mattresses supplied to Ireland's top hotels, the Kaymed Heavy Sleeper Mattress offers a truly luxury 'hotel' feel right in the convenience of home.
  • The single-sided property and inclusion of four turning handles make for fuss-free maintenance, while the robust 10-year guarantee ensures peace of mind for a decade's worth of restful nights.

Cons

  • The firm tension of the Kaymed Heavy Sleeper 1200 Pocket Hybrid Mattress may not be suitable for side sleepers, potentially causing discomfort due to insufficient pressure relief on the shoulders and hips.
  • While the mattress has orthopaedic support, it may not be ideal for those who prefer a softer, more contouring sleep surface, as the firmness could lead to a feeling of sleeping "on" rather than "in" the mattress.
  • The single-sided design, although convenient for maintenance, means that the mattress cannot be flipped to evenly distribute wear and tear, potentially affecting its longevity.

The quest for a sound slumber often feels like an elusive pursuit, yet with the right mattress, it becomes an achievable reality. Tucked within the array of contemporary sleep solutions is the Kaymed Heavy Sleeper 1200 Pocket Hybrid Mattress. This particular model promises a blend of firm support and comfort by using the power of both pocket springs and reflex foam-a hallmark of progressive mattress design. Can this mattress truly offer the spine-aligning, body-supporting capabilities it has? With a well-regarded brand heritage and thoughtful construction, this mattress certainly warrants a closer look, and I'm here to lend my expertise to unveil whether it delivers on its promises.

How we assessed it

On paper this is a firm mattress built for heavier bodies: 1200 pocket springs with a high-density reflex foam comfort layer, 33cm (about 13 inches) deep. My rule is weight first, then sleeping position, so I'd expect a heavier back sleeper to get on with a build like this and a lighter side sleeper to find it a plank. The 1200 count is quoted for a king size, so expect fewer springs in a single or a double.

Design and Features

The Kaymed Heavy Sleeper comes equipped with 1200 individually pocketed springs. This detailed system caters to personalised support, allowing each coil to respond keenly to bodily movements, thereby distributing weight effectively and minimising motion transfer-a boon for partnered sleepers.

Underpinning the pocket springs is a layer of reflex foam, designed to provide orthopaedic-level support that aims to enhance spinal alignment, a vital feature for promoting a healthy sleep posture and alleviating back issues. This synergy between foam and springs is carefully crafted to deliver firm but comfortable support-it's precisely this hybrid construction that echoes through the design inspired by high-end hotel mattresses in Ireland.

The mattress's cover, a soft knitted fabric, is both cosy and breathable. This design ensures enhanced airflow, helping to maintain a cooler sleep environment, which is particularly appreciated amid fluctuating UK temperatures. Added convenience with its single-sided nature also means easy maintenance-there's no need for flipping, just periodic rotations using its sewn-in handles.

Mattress Comfort

In the context of firmness, this mattress firmly plants its flag. The semblance of a rock-solid structure doesn't deter from comfort, thanks to the reflex foam. Still, despite its cushioned embrace, this mattress is decidedly for those who prefer a solid foundation to their sleeping surface. If you are a back sleeper, you'll likely find this ortho-supportive offering perfectly fit for your needs.

The mattress promises a "hotel" feel-plush yet resilient, enveloping the consumer in a supportive embrace meant for rejuvenation overnight. I don't think a firm build like this quite caters to side sleepers, who might find its rigidity a tad overwhelming.

Suitability

Evaluating the user profile most apt for this mattress, it's evident that back sleepers looking for orthopaedic support will find solace in its features. While stomach sleepers may also derive comfort from its structure, side sleepers may need to proceed with caution unless firmer support is their specific requirement.

The Verdict

Ultimately, the Kaymed Heavy Sleeper 1200 Pocket Hybrid Mattress stands as a robust option within its category for those devoted to the firm-support philosophy. With a brand long celebrated for quality springs and clever hybrid compositions, it is a reliable selection, particularly for back sleepers and those with health-driven mattress choices.

Its 33cm depth points to a thoughtfully engineered piece, keenly aiming to offer a bridge between durability and comfort while maintaining a luxurious “hotel-at-home” feel. As the mattress landscape evolves, this slightly varies even the staunchest traditional expectations by supporting a firm orthopaedic route. For those who fit its demographic of seekers, I wholeheartedly recommend exploring it further while remaining cognisant of the narrow user suitability.

Suitability

  • Back Sleepers 4.5/5
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers 3/5
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers 5/5
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.

Performance

  • Breathability 4/5
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress 4/5
  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • Stability 4.5/5
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.

Ease of Use

  • Turning handles 5/5
  • Mattresses typically need to be rotated frequently and having turning handles can be massively beneficial, particularly in larger sizes which can become fairly heavy.

Odour

  • Initial Odour 4.5/5
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour 5/5
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

Brand Rating

  • Overall Brand Rating 4.5/5
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.
