Why Our Sleep Experts Loved It

becky says

As a busy mum, I know firsthand the importance of a good night's sleep and the wonders it can do for a tired body. When I heard about the Sealy Keswick Firm Contract Mattress and its usage in established hotels and air BnBs up and down the country, I knew I had to share it with you all, as it's a bit of a corker!

First of all, let's talk about the PostureTech 660 Response Spring System. This revolutionary technology ensures that weight is distributed evenly across the mattress, resulting in superior support for all of your guests. No more tossing and turning trying to get comfortable - the Keswick has got you (or rather, your guests) covered. We've had first hand experience with the PostureTech spring system in the past and have seen it used in a few different configurations from Sealy over the last 12 months and for good reason. The spring system sits fairly mid-table, offering good body contouring and comfort at a more reasonable price point than traditional pocket springs.

But the technology doesn't stop there as the Sealy Edge Guard provides added durability and a larger sleeping surface for your guests, ensuring that they have the best possible sleep experience. Think of a typical mattress edge, it's droopy and you barely trust yourself to sit on the edge, let alone sleep on the edge. What the EdgeGuard does is reinforce this area allowing you to spread out and get closer to the edges, maximising the surface area while increasing the durability of the springs underneath (since you don't have to be in the same place). Top this layer up with additional hand tufting and finished with a durable and breathable damask cover and the end result is the Keswick, a product not only supportive but also stylish and comfortable too.

Now let's talk about the practicality. The Keswick is specifically designed to meet the demands of the contract environment, making it the perfect choice for hotels and guest houses. And with its compliance with BS7177:2008 Source 5 - Medium Hazard regulations, you can rest easy knowing that your guests are in safe hands (or rather, on a safe mattress). This grading is not optional when considering a product for guest houses and hotels, meaning the Source 5 grading is the minimum requirement necessary to be considered legal.

The above covers the specifications but sometimes it's important to have peace of mind too and if the specifications of this mattresses wasn't enough, the Keswick even comes with a 5 year guarantee. So not only will your guests keep coming back for more, but you can have peace of mind knowing that your investment is protected.

The fun doesn't stop there though and the Keswick is also available in bespoke specifications or sizes made to order. So whether you have a standard sized bed or something more unique, the Keswick has got you covered. The best part? It's made right here in the UK. Support local businesses and give your guests the sleep of their dreams with the Sealy Keswick Firm Contract Mattress.

So if you're a landlord or hotel owner and you are looking to upgrade your guests' sleep experience, look no further than the Sealy Keswick Firm Contract Mattress. Your guests (and your wallet) will thank you.

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews.

Key Performance Indicators KPI question mark

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews. For example, a firm pocket spring support layer is more breathable and offers better back support but may prove unsuitable for side sleepers, the reverse is true for a soft-medium tension reflex foam support layer. This is one of 100+ datapoints considered when generating the below ratings.


*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.


  • 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.


  • 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.

What Makes The Sealy Keswick Firm Contract Mattress Great?

PostureTech 660 Response System for outstanding weight distribution

The PostureTech 660  Response System is a revolutionary and totally unique product that finally addresses the root cause of back pain and neck pain. The system is an innovative mattress design that will help your back by providing the correct amount of support and alignment, allowing you to sleep more comfortably.

Sealy Edge Guard for long-lasting durability

Edge support offers a sturdy border across all edges of the mattress and gives you the opportunity to sleep in more positions and fully spread out on the product, embracing each and every part of the mattress and not having to stick to the middle. This is because the edging is reinforced and gives you that feeling of stability and roll-off prevention while you sleep.

Luxury damask cover

A damask cover has a pattern of small, repeated designs. These small designs are usually made from blocks of color. A damask cover can be made from many different types of fabric, such as cotton, satin and silk.The patterns on the damask covers can be simple or elaborate. The patterns can be made up of one color or a variety of colors.The name “damask” comes from the city of Damascus in Syria. The first damasks were woven in this city.

Hand tufted to secure the luxury fillings

Hand Tufting is a labor intensive process that involves securing the fittings to a mattress rather than having them operate independently and loose within. This small act not only secures, but also leads to the mattress lasting longer and feeling firmer. A hand-tufted mattress is great for anyone looking for additional stability while they sleep.

Supportive, firm feel

Firm Tension Support Mattresses are suited to those who prefer sleeping on their front and back. Typically sleeping on your back helps ensure the spine remains aligned throughout the night and is the most natural sleeping position that can prevent twisting and turning. A firm mattress ensures that a high level of support contours around your body, alleviating pressure across your entire frame in a more even manner than that of a soft mattress, most notably in the hips, neck and shoulders.Finally, if you are suffering from neck or back pain, a firm mattress can help alleviate these problems and result in a better and more relaxed sleep for many years to come.

Engineered to meet the demanding Contract environment

Complies with BS7177:2008 Source 5 - Medium Hazard

A domestic mattress would normally have a level 1 (low-hazard) fire resistance but this mattress goes the extra mile with a level 5 (medium hazard). This is the level of resistance normally used in higher-risk places such as hotels and hospitals.

5 year guarantee

A 5 year guarantee is quite rare in the industry and is a great indicator of the retailer beleiving in their product. Anything go wrong in the next 5 years, no drama, get it replaced.

Made in the UK

These are made and manufactured in the UK, meaning that they all meet the same exceptional quality and durability that we expect from genuine UK manufacturing.

Fire Resistant

Fire resistant does not mean the product will never catch fire, rather, it will not go up in flames quite so quickly. Resistant to fire in the same way that I am resistant to kisses, sooner or later you end up giving in.

PostureTech 660 Springs

A Posturepedic mattress has springs that are connected using a coil. The coil then runs the full length of the mattress, working as a hinge and allowing each spring to move independently into positions to suit the sleeper, contouring to each movement.

Reinforced mattress edge

One of the most common complaints in the industry is against mattresses with a weak mattress edge. It can often result in the user feeling like they are going to fall off the side of the bed and bed avoided. This mattress has a reinforced edge, something that helps ensure that particular scenario is avoided when you get close to a mattress edge while sleeping.

Damask cover

Damask is a fabric, woven in nature that is often used to upholster mattresses. It is typically made from linen or cotton and can typically be woven into delivate detailings required by the supplier. The fabrics are typically fairly hard wearing and should not cause problems

Bug Shield

The bug shield in this mattress is able to protect against bugs and mites. the shield works well to ensure that you get a great and clean nights sleep.


Firm mattresses are great for those looking for an extra bit of support, either because they have a higher BMI and leanm toward the heavier side, or because they have joint and muscle pain and appreciate a decent amount of support while they sleep. If you are not actively looking for a firm mattress it may be wise to consider something else from the range that is perhaps closer to the medium firmness rating

27cm deep

27cm is a deep mattress. You may require deeper sheets in order to be able to comfortably get them around the mattress. Regardless though, the general rule of thumb is that while depth is not entirely an appropriate guage of quality, you cannot get a good quality mattress with decent comfort and support in a thin frame. This size of mattress definitely adds credence to the fact that it is likely to be made of good quality internals and stand the test of time.


Double sided just means that the product can be flipped and still retain the same level of comfort. The fillings and dibres inside the product are capable of operating in any direction. Handy for settlement and to prevent dipping.

Includes turning handles

Oh turning handles are pointless I hear you say. Just try flipping and turning this product without handles. It can be a pain. Remember that mattresses should be both rotated and flipped frequently, not a problem if you are opting for a sinle, but those doubles and kings can get heavy. Handles are very good.

Handcrafted in the UK

Handcrafted in the UK means that the product is built here, by people being paid a fair and honest wage using certified and safe products of good quality and construction. UK manufacturing is some of th best in the world and all of that is reflected in this product

Approved by the National Bed Federation

The NBF is one of the most prestigious awarding federations in the industry, helped slightly by the fact that it is one of the only, however, it is still a great source of comfort knowing that this product holds approval by the team

Customer Reviews For The Sealy Keswick Firm Contract Mattress

Based on 1 reviews

I'm a really big guy and I was constantly buying new mattresses because I would always put too much pressure on one spot, so they would start sagging. This one is different though, it's firm enough to take my weight and feel really comfortable at the same time. It's great.
