Overview

becky says

Many of the mattresses that I review are ones that I have gone to a store and tried out, other times I make a best judgement based on the specifications and reviews accumulated against products. Not in this instance however, this is my mattress and one that I have owned for the last couple of years. I have slept on it every night and can give genuine insight into suitability. 

Let's start with the support layer, this layer comes in the form of 1500 firm pocket springs that mould to your every movement. They are of extremely good quality, they do not creak or grown or make any noise whatsoever, but, they are firm and depending on your body type and personal preference will determine whether this is suitable or not.  

The comfort layer comes with a massive 75mm of memory foam. Did you know a large chunk of "memory foam" mattresses have as little as a 20mm layer of foam? 75mm is huge and you cannot feel any of the individual springs underneath the foam at all.

When it comes to preference, I really like this mattress both as a side sleeper and a back sleeper. However, my partner found it slightly too firm and insists a softer mattress would be more suitable for side sleeping when you have a bit of a "booty" and hourglass figure as the sinking feeling of the memory foam is slightly subdued with the firmness of the springs. Do not let any of that take away from what is a beautiful mattress that is supremely well made. 

Pay for room of choice delivery over delivery to the front door because this thing is really, really heavy. My partner and I spent 20 minutes and a lot of sweat getting it up a relatively small flight of stairs, pay the extra few quid and let someone else handle it.

How does it feel?

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.

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

  • 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.

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.

What Makes The Horizon Discovery 1500 Pocket Memory Mattress Great?

1500 responsive pocket springs provide incredibly personalised support

Pocket springs are probably the best support layer you can get in a mattress helping to provide measured and even support across your body where you need it most. What's more, the unique feeling of pocket springs hugs each point of your body, offering contouring across each pressure point to relieve aches and pains. Lesser models will frequently include alternatives to pocket springs like open coil traditional springs and reflex foam. Do not be fooled, while pocket springs are often slightly more money than their counterparts, you are typically getting a better spring system and base layer.

Super-deep memory foam layer for out-of-this-world comfort

Memory foam has properties that adapt shape of your body, immediately recovering its original shape once pressure is no longer applied. It adapts to your movements without sinking, ensuring that pressure is not produced, but without the wrapping feeling which would otherwise cause unnatural posture.

Extra breathable, fresh and cool - no overheating

Pressure-relieving and highly beneficial for your joints and back

Perfect balance of comfort and support - rated medium

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.

The mattress sides are reinforced with sturdy foam

No roll-together or roll-off - simply peaceful sleep

A good rigid support layer with full edge to edge support means you do not get the sinking characteristic associated with poorer quality mattresses when you move toward the edge of the mattress. This is great as it prevents falling out of the bed at night, but also prevents roll off and roll together allowing both you and your partner to have uninterrupted deep sleep.

Reinforced mattress border also provides more sleeping space

The cover can be easily zipped off and removed for dry-cleaning

Hypoallergenic - an excellent choice if you suffer from allergies

Allergy sufferers often experience the problem of waking up in the middle of the night or having to get up in the morning with a stuffy nose and eyes. The reason why you wake up with a stuffy nose is because your mattress has accumulated dust mites, mould and mildew, all of which are allergens. The solution is a hypoallergenic mattress is made from materials that do not support mould or dust mites. They also have anti-microbial properties that effectively kill any bacteria that may come into contact with it.

Single-sided for easy care - no need to turn over

A single sided mattress is typical for the industry and relates to how  a mattress has the comfort layer on one side of the mattress. only This means that the mattress only needs to be rotated rather than flipped. The benefit of single sided mattresses is that they require less upkeep in that there's no flipping, but also, there's less components involved in the creation which saves costs.

Rolled up for your convenience

Roll up mattresses, also known as bed-in-a-box mattresses are fairly new to the scene, first cropping up via the likes of Eve and Simba back in 2016. Since then there has been a rise in popularity due to their lower price point (due to delivery and storage costs) and their convenience for getting up stairs. Typically these mattresses have much the same support and comfort as a traditional mattress even with the positive points mentioned.

Depth: 27cm

The industry standard for mattress depth is 7 inches. With most offering a comfortable 10 to 14 inches, so this one at 10 inches is one of the most popular sizes. The higher the load, the deeper it needs to be but a quality mattress in this size can be equally as comfortable and supportive as a deeper budget mattress. 

10 Year Guarantee

A 10 year guarantee is a huge reflection of just how much trust the manufacturer and the retailer have in their product. for reference, mandatory requirements are for a 1 year guarantee.

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.

Pocket springs

Pocket springs are like natures own springy piece of comfort, except they are not from nature. Alas, pocket springs are a very good part of a mattress and often found in the more premium models. Lower quality products will frequently use open coil spring setups, where pocket springs house each spring in a tiny pocket for additional stability and continued support. Pocket spring typically lasts longer than open coil due to this.

Memory Foam

memory foam is one of the most well known materials used in the upper layer of mattresses. Memory foam basically contours to your entire body with moulding properties. Designed by NASA, this material rebounds to your touch and feels like you are floating on a cloud. Memory foam does not necesserily mean soft either, you can still have firm mattresses for those that want them with a bit of memory foam.

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.

Removable cover

Removable covers are great. We don't typically replace mattresses for 7-8 years. That's a lot of body fluids and protectors and sheets can only do so much. To that end getting that extra layer of cleanliness goes a huge way toward ensuring you get longevity out of your product.

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.

No roll-together

Nobody wants to wake up in a sweaty mess, conjoined to their partner. This generally happens when you both end up rolling into the middle while you sleep and is common with lower quality mattresses that do not half roll-together prevention. Truth is, any good mattress with adequate support structure should be roll-together by default. This specification tells you that the mattress should be of adequate quality.

Pressure Relief

One of the big complaints when settling into a new mattress is that it does not feel as comfortable as they hoped, where this mattress shines is in the enhanced pressure relief that it offers. Each part of your body exerts different amounts of pressure against the mattress and through the use of springs and foams, these products are able to offer significant pressure relief as a result across the entire body.

Hypoallergenic

This product is unlikely to cause any sort of allergic reaction. Ideal if you suffer from any sort of allergy problems

Medium

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.

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.

Rolled-up

Rolled up mattresses are ideal for anyone looking at trying to get a mattress up a tight staircase or in a car to bring home from the shops. Do not missunderstand just how troublesome getting a mattress up stairs can be. Heavy and cumbersome, sometimes a rolled up mattress that expands to the side of a full mattress anyway, may be the better option

Single-sided

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.

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
