Why Our Sleep Experts Loved It

becky says

The Sealy PostureLux Forbes Mattress is a high-quality sleep solution that has been designed to provide comfort and support to people who want a better night's sleep. It features a medium comfort grade, which means that it offers a balance of softness and firmness that may be suitable for a wide range of people. When it comes to suitability, we generally recommend medium tension mattresses for combination sleepers who sleep on their back, side or stomach. The tension is known as the goldilocks firmness thanks to its mass suitability meaning that if you are not too heavy or light, on average you will find success with this type of tension.

The comfort layer of the Sealy PostureLux Forbes Mattress is made up of a latex layer, which provides a sumptuous, comfortable feel. This layer is supported by a double layer of medium premium foam, which helps to alleviate pressure points and improve the overall sleep experience. These comfort layers work together to create what the retailer and manufacturer reference as a "complete comfort stack" that helps to keep the body comfortable and supported throughout the night.  It's not a combination we have seen before, but it's one that could work particularly well for providing an extra-deep unique comfort layer.

The support layer of the Sealy PostureLux Forbes Mattress is where the real magic happens. It features Sealy's exclusive PostureTech Core Support Plus™ spring system, which is designed to provide exceptional support and keep the spine in proper alignment. This helps to prevent discomfort and pain, and can contribute to a deeper, more restful sleep. We see this support layer in a lot of the new Sealy lineup from 2022 onwards whereby Sealy have refreshed the entire range with mid to high range products with better support. The support layer itself works particularly well, offering enhanced posture while still being soft enough for medium sleepers regardless of how they sleep.

In addition to its comfort and support layers, the Sealy PostureLux Forbes Mattress also features some advanced technology that helps to promote sleep health. For example, it has SilverFresh™ technology, which prevents the build-up of bacteria, and it has been certified by Allergy UK for its ProShield® technology, which helps to keep allergens at bay. These features can help to create a clean, healthy sleep environment that is more conducive to a good night's rest.

What's more, the Sealy PostureLux Forbes Mattress is handmade in the UK and comes with a 40-Night Sleep Guarantee, which allows customers to try out the mattress and see if it is a good fit for them. It also comes with a 5-year manufacturer's guarantee, which gives customers peace of mind and assurance in the quality of the product. The combination of these two benefits makes it one of the better choices on the market today as you have the reassurance that the product will stand the test of time.

About The Brand

Sealy is known for its commitment to quality and innovation in the sleep industry, and has a long history of producing high-quality mattresses that are designed to provide comfort and support to help people get a better night's sleep.

The company has a global presence, with products available in more than 100 countries around the world.

Final Thoughts

Overall, the Sealy PostureLux Forbes Mattress is a well-made, high-quality product that is worth considering if you are in the market for a new mattress. It offers a combination of comfort, support, and technology that promotes sleep health, and it is suitable for people who prefer a medium level of firmness and want a mattress that will alleviate pressure points and keep their spine aligned. Those with more specific needs, along with those who require additional back and neck support, should instead consider a firmer variant in the range. Those who are of a lighter BMI who sleep dedicated on their side, could consider a softer tension than this one, however, the medium does do a fairly good job that should prove suitable.

How does it feel?

Firmness of The Sealy PostureLux Forbes Mattress depends on bodyweight. Adjust your weight below to get an indication of how it may feel. Remember though that firmness is entirely subjective.

Reasons to Buy

A lot of new Sealy tech is included in this mattress, from the SilverFresh to the Core Support spring system. We expect these technologies to begin making their way down through the rest of the range over the next year or so.

Established retailer with a reasonable 5 year guarantee to help ensure consumer confidence.

Latex is one of the more preferable comfort layers thanks to its great breathability, making for the perfect all-season mattress.

Reasons to Avoid

Sealy have relaunched in the UK, pulling al previous products in their lineup and reinventing themselves back at the top with some ultra-premium mattresses. Unfortunately this comes at a price point that may well alienate most people looking for a mattress that has the specific benefits listed. For those that can afford it though, the PostureLux really is a fantastic choice for mixed combination sleeping all year round.

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.


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


  • 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.

What Makes The Sealy PostureLux Forbes Mattress Great?

Premium Sealy PostureLux patented mattress

Not only is the tech in this mattress unique to Sealy, but it is also unique to the PostureLux collection which is a small range coming out of the company toward the end of 2022.

It has a medium comfort grade

Medium tension mattresses are suitable for the vast majority of people as they are not too soft, nor too firm. This firmness can offer a good amount of back and neck support while still being soft enough to prove suitable for side sleepers. The key benefit for this type of layer is that it's sort of a "one size fits all" approach that gives your body the contouring and support necessary while remaining soft and squishy.

Exclusive PostureTech Core Support Plus™ spring gives exceptional support, available only at Dreams

Unique to Sealy, this design of spring is made of high-quality materials and has a specific design that helps to evenly distribute weight and reduce pressure points.

Features a latex layer for sumptuous comfort night after night

Combined with a double layer of Sealy's medium premium foam for a complete comfort stack

SilverFresh™ technology prevents build-up of bacteria to promote sleep health

SilverFresh technology is a unique technology developed to provide antimicrobial properties. Silver has long been known for its antimicrobial properties and has been used in a variety of applications, including medical treatments and consumer products.

Allergy UK have certified Sealy's ProShield® technology which keeps allergens at bay

The ProShield® technology used in the mattress is effective at reducing the presence of allergens such as dust mites and pollen, which can trigger allergy symptoms in some people.

Handmade 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.

Comes with our 40-Night Sleep Guarantee

The 40 night sleep guarantee is great as it allows you to exchange the product if you are not completely satisfied. This was one of the final challenges for online retailers to overcome comparable to traditional bricks and mortar where you can trial the product in store. Buy with confidence on this model.

Rest easy with a 5-year manufacturer's guarantee

A 5-year guarantee is generally considered to be a good length of time for a mattress guarantee. This provides a reasonable amount of protection for the consumer and demonstrates that the manufacturer has confidence in the quality of their product.

Customer Reviews For The Sealy PostureLux Forbes Mattress

Based on 16 reviews
Comfy but hot!

The mattress is comfy and supportive but I am finding it very hot to sleep on. Our bedding and duvet hasnt changed just the mattress. Its also very deep so you will need extra deep sheets. The grey bottom edge of the mattress shows through the side of white bottom sheets which is a shame. We dont roll together in the middle so from that aspect the mattress is good.

Wish I'd purchased sooner

Slept like a log for the first time in ages, from the first night following the delivery of my new mattress. Unfortunately, aches and pains from ageing have slowly crept up on me and I hadn't realised quite how bad my very old, original mattress was!! Good support but also very comfortable. Highly recommended.

Comfy mattress and good service!

Great mattress so far, very comfy and good service from Dreams. Remains to be seen on how well it weathers over time. We were set on getting a Sealy after trying many brands and even returning another mattress. Would absolutely recommend Dreams and Sealy so far.

Back pain gone!

I have had a bad back for a while and the first night sleep in this recommended mattress from the shop my back no longer hurt! Very impressed and happy with the service

Fabulous mattress

I was unsure because theres so many to choose from but if u have back problems then this is a very good well made mattress ! Top ratings from us ! Even the dog

Very comfortable

The Forbes is a sturdy and comfortable mattress. The structure stays in tact as you climb in and out of bed, however provides incredible support as you sleep.

Comfy mattress with plenty of support

Very comfortable. Manages to be both fairly soft yet also holds enough firmness to stay flat so we don't roll together in the middle.

Dreams, why go anywhere else.

The mattress is very comfortable and a great choice. The Dreams sales staff were excellent in helping us choose the right one.


Incredible. 100 times better than we could have imagined. Great advice from the Dreams staff means we have never slept so well
