Why our sleep experts loved it

Embarking on a quest for a perfect night's sleep can be a daunting task, especially with a plethora of mattress options available in the market. Amidst the myriad of choices, finding a mattress that meets your specific needs regarding comfort, support, and sustainability can be quite a challenge. Enter the Silentnight Castleton 800 Pocket Sprung Eco Mattress - a cutting-edge product that promises to match the sleeper's need for comfort with conscious efforts in sustainability.

How We Test

In order to provide a comprehensive and reliable review, we committed extensive time examining the Silentnight Castleton mattress in-store. We put it through a stringent series of tests, assessing the mattress for comfort, support, breathability, and its eco-credentials. We also compared its performance under different conditions, including in a cooler store environment and when subject to constant pressure, just as it would experience in a home setting.

Design and Features

The Silentnight Castleton 800 Pocket Sprung Eco Mattress is teeming with notable features, all designed to render an unparalleled sleeping experience for a wide range of sleepers. Harmonising medium comfort grade and Eco Comfort Fibres™ created from recycled plastics, this mattress offers well-rounded support while standing proud in its sustainable initiatives.

The surface is laced with a beautifully soft, hypoallergenic knitted cover, adding a luxury touch to the product. Arguably, one of its most remarkable features is its construction around individual Mirapocket® springs, providing a customized and zoned support system catered to your body.

Mattress Comfort

The Silentnight Castleton mattress offers a perfect balance of support and pliability. Ideal for back and side sleepers, this medium tension mattress provides a high level of comfort, and encourages an improved sleeping posture, but it can offer a sufficient level of comfort for stomach sleepers as well. Its eco comfort fibres are breathable and work remarkably well in maintaining an optimum sleeping temperature.

Suitability

This mattress is suitable for a broad spectrum of users, given its universally engaging medium comfort grade. It is especially ideal for average-weight individuals, regardless of their sleeping position. The design of this mattress offers excellent countouring and support, proving particularly beneficial for back sleepers by providing additional comfort and support.

What Customers Thought

Customer reviews have been rather mixed, though it's important to take each with a unique context. Many lauded the Silentnight Castleton for its excellent support and commendable comfort level. The cooling feature of the mattress, which can be attributed to the Eco Comfort Fibre™ layer, also received much praise.

A few customers, however, expressed views about the mattress size being slightly smaller than expected. Others mentioned that the firmness of the mattress caused mild discomfort, though these reports seemed to lessen over time, suggesting a potential breaking-in period. There was also mention of the Silentnight logo being misaligned, though this does not affect the performance and overall experience of the mattress.

The Verdict

The Silentnight Castleton 800 Pocket Sprung Eco Mattress brings forth a harmonious blend of comfort, support, and sustainability. Its combination of medium support and the advanced Eco Comfort Fibre layer makes it a stand-out choice among the competitive mattress landscape. While its firmness has rendered mixed reviews from customers, the general consensus remains positive. Whether you're an eco-conscious shopper or prioritise comfort and support over all else, the Silentnight Castleton could be an excellent choice.

  • Back Sleepers
    ★★★★★
    ★★★★★
  • 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
    ★★★★★
    ★★★★★
  • 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
    ★★★★★
    ★★★★★
  • 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.

    ★★★★★
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
