Why our sleep experts loved it

The Sealy Derwent Contract Firm Mattress has received rave reviews from customers for its comfort and support but what is it that makes this one stand out? The PostureTech 660 Response System is designed to offer excellent weight distribution and support, which has helped many users sleep more soundly and wake up feeling refreshed with enhanced body contouring leading to additional support. Further to this, the Edge Guard feature provides edge-to-edge support, ensuring that the entire sleeping surface is stable and comfortable, maximising surface area and increasing durability.

The mattress is covered in a luxurious micro-quilted soft damask cover, adding to the overall comfortable feel of the product. It is also firmer in feel, so it may not be the best choice for those who prefer a softer mattress or who sleep on their side in a dedicated capacity. However, the firmness of the mattress has been praised by many users who prefer a firmer feel for enhanced back and neck support.

One of the standout features of the Sealy Derwent Contract Firm Mattress is that it has been engineered specifically to meet the demanding requirements of the contract environment. It is also compliant with BS7177:2008 Source 5 - Medium Hazard, which adds to its overall quality and durability.

Customers have also appreciated the option to order bespoke specifications and sizes, as well as the availability of quantity discounts for larger orders. The 5 year guarantee is an added bonus, giving users peace of mind about their investment. The fact that the mattress is made in the UK is another plus for many customers.

What does source 5 mean?

In the context of the Sealy Derwent Contract Firm Mattress, "Source 5 - Medium Hazard" refers to the level of fire resistance of the mattress. BS 7177 is a British Standard that sets out the requirements for the fire resistance of mattresses, pillows, and upholstered bed bases.

Source 5 is the category for medium hazard products, which are intended for use in environments where the risk of fire is higher than normal, but not at the highest level. Examples of such environments include hotels, hostels, and student accommodation.

In order to comply with BS 7177:2008 Source 5 - Medium Hazard, the Sealy Derwent Contract Firm Mattress must have a certain level of fire resistance, which is achieved through the use of special fire-resistant materials and construction techniques. This ensures that the mattress meets the necessary safety standards for use in commercial environments where the risk of fire is higher than normal.

Customer feedback and long term reviews

It appears that overall customers have had a positive experience with the Sealy Derwent Contract Firm Mattress. Many customers have reported that the mattress is comfortable and provides good support, with a few customers stating that they get a "good night's sleep" on it.

Some customers have mentioned that the mattress took a bit of getting used to due to its firmness, but overall they have found it to be comfortable. One customer mentioned that the mattress is cool, which could be a desirable feature for some users.

There are a few reviews that do not provide any specific feedback about the mattress, but overall the majority of the reviews are positive and suggest that customers are satisfied with their purchase.

Suitability

*Assuming average weight, suitability will vary dependant on body type, use the quiz above for a more tailored guide.
  • 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.

Performance

  • Stability
    ★★★★★
    ★★★★★
  • 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
    ★★★★★
    ★★★★★
  • 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
    ★★★★★
    ★★★★★
  • 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
    ★★★★★
    ★★★★★
  • 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
    ★★★★★
    ★★★★★
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.
