What our reviewers found

Pros

  • The mattress offers enhanced temperature regulation with its Staycool™ Gel foam layer, resulting in a cooler and more comfortable sleep environment.
  • It provides firm support yet gentle cushioning due to its high-density comfort layer and plush polyester layer, effectively easing aches and promoting better sleep quality.
  • Featuring 1600 independent pocket springs, the mattress adapts to individual body contours, helping reduce motion transfer and providing full body support.
  • Its microquilted finish and cool-touch surface create a soft, smooth, and refreshing sleep surface.
  • Equipped with air vents along its border, the mattress promotes breathability, helps maintain a fresh feel, and prevents the build-up of allergens, contributing to a healthier sleep environment.

Cons

  • Though highly supportive, the firm tension of this mattress might not be suitable for individuals who are side or light sleepers, as it may not adequately conform to the body's natural curves, leading to possible discomfort or pressure accumulation.
  • While the Staycool™ Gel foam layer provides a fresh feel, it might not be suitable for those who feel the cold easily. The cooling effect could potentially make them feel uncomfortable, particularly during colder months.
  • Despite the 1600 pocket springs offering independent movement and thus minimising sleep disturbances due to partner movements, the mattress may still not completely eliminate motion transfer, possibly causing disruptions for extra sensitive sleepers.

How we assessed it

The Sleepeezee Cool Refresh 1600 Pocket Mattress is a firm, single-sided mattress, 24cm deep, built on 1600 pocket springs (that count is for the king size). The comfort layers are a microquilted cool-touch cover, a soft polyester layer, 2cm of Staycool™ Gel foam and a high-density support layer. A 2cm foam layer won't let you sink far, so I'd expect you to lie on this mattress more than in it, and the firm rating looks right to me. That points to back sleepers first. Sleep on your side and you will want something softer. Heat should be the stronger suit: springs let air move, the border has vents and the gel foam layer is only 2cm deep. An owner with a king size backs the cooling up. As with any review I offer, let me stress the necessity for scepticism; after all, the best sleep solutions are an investment in your health and comfort.

Design and features

The Sleepeezee Cool Refresh 1600 Pocket Mattress, with its elegant design and technological enhancements, manages to stand out in a saturated market. The mattress fosters cooler comfort, taking advantage of a 2cm layer of Staycool™ Gel foam alongside a unique cool-touch sleeping surface. This subtle cooling effect matches our bodies' natural inclination to lower core temperature during sleep, thus encouraging better rests.1

Supported by 1600 individually encased pocket springs that move independently, this mattress provides tailored body support, contouring carefully to your unique weight and shape. This design comes alongside a high-density support layer, promising to prevent sagging over time, and a soft polyester comfort layer strategically placed to balance firm support with gentle cushioning.

Mattress comfort

Although the Sleepeezee mattress offers considerable firm support, potential consumers-particularly side sleepers-may find it too rigid for their liking. There's no denying the quality of its high-density support layer and the resilience it offers, however, the limited softness could be a sticking point for some. To my mind, side sleepers could find this firmness bordering on uncomfortable, inhibiting the quality of their sleep. Conversely, back sleepers, and possibly some stomach sleepers, could find the orthopaedic qualities beneficial.

Suitability

This mattress, with its combination of cooling gel technology and firm pocket sprung support, is best suited to those with a preference for a noticeably firm sleeping surface. It is particularly aimed towards back sleepers or those recommended by medical professionals to opt for an orthopaedic level of firmness. The mattress' heat regulating features may appeal to those who sleep hot. However, the lack of softness and contouring is a drawback for side sleepers or those who enjoy a plush sleeping experience.

What customers thought

Owner reviews are short and positive. One owner with a king size wrote that it is "very comfortable and the cooling effect works very well", and went on: "I used to feel hot under my goose down duvet now I am always at a very comfortable temperature". Another review is a single word, "Excellent". The firmness is still the thing to weigh up if you sleep on your side, and the mattress is single-sided, so you rotate it instead of turning it over.

The verdict

Despite its potential shortcomings for particular sleeper types, the Sleepeezee Cool Refresh 1600 Pocket Mattress delivers commendably in the areas it claims to. The high density support layer, combined with the Staycool™ Gel foam layer, presents an intriguing proposition for those seeking a cooler, firmly supportive sleep. However, the relative rigidity of the mattress may deter some potential buyers. For those in need of orthopaedic support or those recommended a distinct firmness by a medical professional, it's worth investigating. Yet, for side sleepers or those preferring softer support, you may want to explore alternatives. Despite its impressive features, the mattress fails to satisfy the broad sweep of sleeping preferences and styles.

Discerning buyers might also raise eyebrows at the Staycool™ Gel, scrutinising whether its proclaimed effects meet their expectations or merely serve as a marketing tool. The perceived coolness benefits could be overhyped and may not suit everybody. Such is the subjective nature of the mattress industry - even the most advanced, luxurious mattresses aren't immune to controversy. With our focus cemented on factual analysis, personal needs and preferences are, as usual, paramount when making the final buying decision.

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 5/5
  • 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.
