becky says

Today we're looking at something new to the Relyon line-up and one that is yet to be reviewed by other customers. Don't let the lack of reviews put you off however, Relyon have plenty of clout in the industry and know their way around mattresses. The 650 designator in the name comes from the open coil traditional spring quantity which we be looking at in more detail further down.

Let's  unpack this and start with the support layer. The support layer is the area that typically features the springs, but occasionally can feature a foam layer. It it the area which helps protect your back and spine, providing the support necessary to enjoy a good night's sleep. While support can relate to comfort, it is more about contouring to your body and ensure you do not wake up in pain.  The traditional spring system is sufficient and features a medium tension. What I like about the medium tension here is that it will largely suit most people regardless of the position you sleep in nor you or your partner's weight. There are exceptions to this obviously, overweight or underweight should consider perhaps a softer or firmer option, but generally this is considered the goldilocks of comforts and the sweet spot.

Onto the comfort layer and you get a quality plush, pillow-soft quilting over the top to protect you against the springs beneath and to provide an extra taste of luxury. combined with this you have soft white fibre fillings that are also wonderfully comfy relative to the price point and one that should work well with the open coil springs.

Finally you have the smooth knitted cover that is both soft and durable. The combination will ensure that your mattress remains protected. You also have turning handles as part of this cover and while you do not need to flip the mattress, you should still rotate it head to toe in order to help with settlement and prevent dipping over its lifespan.

Reasons to Buy

The Comfort Pure 650 Mattress by Relyon is a part of their Comfort Collection. Designed to offer a medium level of comfort, this mattress is not too soft, but not too firm. The double layer of open coil springs gives double the comfort and support, ensuring that you get the best night's sleep. The mattress features an easy to clean and easy to move with white knitted cover.

You also get a 5 year guarantee which is pretty amazing given the low price point. Relyon clearly have a lot of confidence in the makeup of this product and that should instill further confidence in it. Ultimately, this is a mid-range mattress at a fairly budget price point and well worth a consideration.

Reasons to Avoid

A single sided mattress has the benefit of not needing to be flipped. However, the downside to this is that you only have one side of fillings which may slightly reduce the lifespan of the mattress. After all, when both sides have comfort layers you an maximise double the surface area on which you sleep. That said, you do get better value in initial costs as you are paying for less luxury materials so it does even itself out.

The only other stand out negative in this mattress would be around the spring system. While perfectly suitable for the majority of people, open coil traditional spring is beaten in most scenarios by the pocket spring support layers in more expensive mattresses. However, it all comes down to value, this mattress will largely be suitable for most people and at the price point there is simply no way to feature a pocket spring layer as an alternate.

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 Relyon Comfort Pure 650 Mattress Great?

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

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.

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

Part of the Comfort collection by Relyon

Relyon mattresses are built with the highest quality materials and craftsmanship. Designed for a huge degree of comfort, they include a great all-round measured support with a comfort layer on top that instantly absorbs movement and provides pressure relief. The comfort collection provides support and durability for years to come, so you can sleep soundly knowing that your mattress will stand the test of time.

Featuring a dual-layer of 650 supportive open coil springs

Open coil mattresses feature a traditional spring design that dates back centuries. They are a low cost solution for bed retailers that provides a good quality sleeping solution that is capable of providing adequate body contouring and reasonable support.

The double layer of springs gives double the comfort and support!

Rated medium - not too soft but not too firm

A medium tension mattress like this is the goldilocks of mattress tensions. Not too soft, nor too firm, medium is typically suitable for the vast majority of people that are looking for a good nights sleep. If you are of average build without back or neck problems, this should be a suitable product. If you are of lower BMI and a side sleeper, consider a softer mattress, whereas if you are of a higher BMI and suffer neck and back pain, consider a firmer tension.

Plush, pillow-soft quilting for extra luxury

A pillow top works as a permanent additional comfort layer that sits at the top of your mattress offering an additional degree of thickness to help separate you from the base support layer. Ideal for those who want more softness and luxury that allows them to sink deeper.

Soft white fibre fillings are wonderfully comfy

Smooth knitted cover is micro-quilted to lock in the plush fillings

A knitted cover offers a number of advantages over competing products. These covers are breathable which helps keep you cool and the mattress hygienic resulting in a cooler nights sleep that has you sleeping deeper for longer. Knitted covers also have the benefit of being softer than many others making them an ideal choice.

No-turn for easy care - simply rotate every month to keep in great condition

It is import to rotate your mattress because it helps ensure even settlement of fillings and ensure even distribution is maintained. Further to this it also means that more than one area of the mattress is used equally, increasing longevity and lifespan as part of typical mattress care.

Easy to move with built-in turning handles provided

Depth: 29cm

29cm is a fairly good depth for a good quality mattress. Plenty of room for a decent spring system and enough fillings to provide more than enough comfort. While depth is not necessarily a guarantee of quality, it certainly helps.

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.

Traditional open coil springs

Open Springs offer fairly decent support that is evenly spread across the mattres. However, where budget allows, we would tend to steer people toward a pocket spring mattress, these might be a little bit more money, but the support is superior and consistant across the product

Soft white fibres

White fibres tend to be a mixture of polester and other non-descript synthetic fibres

Knitted Cover

It is common in the industry to have a knitted cover, these covers can come in a variety of patterns but are typically hard wearing and do not present problems for consumers.


A Medium firmness mattress is the most common build offered due to the range of suitability offered in such a mattress. This type of mattress will be better suited toward averagely weighted people, while lighter people should opt for a medium-light, and heavier people considering a medium-firm.

29cm deep

Most experts recommend a minimum of 4 inches on the top layer and 6 inches for the core so this is ideal at 11/12 inches. Generally, the heavier the load the deeper the mattress should be. This depth covers a wide range of body type sitting comfortably in the most popular section of the scale.


Single sided means only one side is comfy. Positives are you only need to rotate the mattress occassionaly rather than the more cumbersome rotate and flip. Downside is the lifespan of the product may suffer as a result, only marginal, but worth mentioning.

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.
