Why Our Sleep Experts Loved It

becky says

Do you have trouble falling asleep because of your mattress? Are you not getting enough rest because your mattress is uncomfortable and causes pain in your back, neck and other parts of your body? If so, a new mattress could be the solution to your problem. Orthopaedic mattresses are specifically designed to alleviate pressure from sensitive areas on the body such as the spine, hips and shoulders. They achieve this by offering enhanced support for these problem areas. Let's dive into the specifics starting with the comfort layer that sits at the top.

A Sealy Ortho Plus Silver mattress is made of MemorySense Foam comfort filling, this is a variant of memory foam that has been in use since NASA first developed it decades ago. This variant is fairly new and unique to Sealy, as such long-term reviews are still out for verdict. In the short term, however, this foam has proven just as adept at proving a luxurious and soft upper layer that is fast becoming a fan favourite.

Onto the base layer and the mattress features PostureTech springs that are designed to relieve pain in the back, hips, shoulders and other problem areas. It is a great option for those who are looking for a mattress that can offer relief from common aches and pains caused by ageing or poor sleep posture. The PostureTech springs have been around long enough now to become established and are one of the front runners in the orthopaedic arena for their fantastic support and reasonable price point. Do be aware, however, that the wound tension on these springs is firmer than standard and as such we have a medium-firm designation which might mean that side sleepers of average build may not find the comfort they are looking for with this type of support system. For those who are predominantly sleeping on their back, this is a strong support layer that is reinforced by a fantastic 5 year guarantee, highlighting the great quality and craftsmanship that has gone into the design and materials in a Sealy mattress.

When it comes to mattress depth, there is no right or wrong answer to an extent, and in this case, the mattress comes in at a respectable 25cm thick which is deep enough to reinforce the quality inside, but not too deep that you need to consider new specialist sheets, a win-win for the consumer.

Customer feedback is so far excellent but it is important to note that there are no long-term reviews of this particular Sealy configuration. This is because Sealy has recently deprecated their entire product line-up as part of a UK-wide refresh and we are only just (at the time of writing), through to the other side. As such, we have 30+ reviews so far, all of which are extremely positive with many happy with the great compromise between a slightly higher firmness and the rewards of orthopaedic feel for the back and neck. People are also complimentary of the price point which fits securely in the lower to mid quadrant, something which is sure to delight people enduring current economic hardship.

How does it feel?

Reasons to Buy

A Sealy Ortho Plus Silver mattress offers many benefits that can improve the quality of sleep and while the configuration shown here is new, the PostureTech springs utilised have been a staple of good quality Sealy mattresses for a much longer period with much fan-fare and customer happiness.

All popular UK sizes are available although limited Euro sizing on offer.

Next day delivery available for choice options as of now.

Reasons to Avoid

Somewhat specialist mattress that won't suit those not looking for orthopaedic style support, although the medium firm tension may expand suitability somewhat versus the traditional firmer experience shared by many in the orthopaedic space.

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 Ortho Plus Silver Memory Mattress Great?

PostureTech Core Support Springs

Providing even weight distribution, the PostureTech spring system feels soft then gradually gets firmer as pressure is applied. The entire spring unit is twice tempered, making it strong. Their Smaller diameter means they can fit more into an area, allowing for a more fine-tuned level of support.

25cm deep

A 25cm mattress is a good depth for a product of quality. Plenty of room for some good quality springs and enough space for a good top layer of comfort. This side of product should just about fit a standard sheet but do not be surprised if you find you do need to upgrade to a deeper fill sheet to fit over the mattress.

Medium Firm Support

Medium Firm is a tension that ranks around 7 out of 10 on the firmness scale. Where 5 is considered the standard average firmness, a 7 is slightly firmer. This tension is still largely suitable for the vast majority of people, especially those that like sleeping on their back, or, suffer from back/neck pain that requires a firmer feel.

Orthopaedic Support

Do you suffer from back pain? If so you will likely find that an orthopaedic mattress will be massively beneficial to you. Slightly firmer in the comfort side of things but ultimately with a better support layer means that your back and neck will thank you for years to come.

Reinforced Edges

Reinforced Edges provide a higher density area around the mattress supplying a stronger resistance to pressure.  As well as preventing the mattress from sagging and extending its lifespan the firmer edges give you extra usable space and edge to edge support.

No Need To Turn

This means that the product does not need to be turned over, but make no mistake, that is not the same as saying a product does not need to be rotated. If you do not want dips in your mattress with time, be sure to rotate evenly every month where possible

No roll together

Specifically designed with roll together prevention in mind. This means the product likely has better quality internals and offers better support than other mattresses in the same price point.

Turning Handles

Have you ever tried rotating or flipping a mattress without handles? You have to do that weird thing where you use your head as a third arm as you sort of nudge it with your face. Take the handles as a blessing

Hand Tufted

A tufted mattress is often a sign of high quality, Unlike quilted mattress which binds the soft layer directly to the other layers, traditional tufting uses several thick straps to hold the layers together through the spring unit, binding it at each side.

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.
