Why Our Sleep Experts Loved It

becky says

The Jessica 800 Pocket Support Mattress is a new product from Sleepeezee that builds upon the foundation of last years Jessica mattress, adding variants around comfort layer and firmness to ensure mass-market appeal.

The Jessica is endorsed by Jessica Ennis-Hill, a gold medal Olympian and Dame. Jessica helped design this product due to her belief in sleep and rest being a key factor in training.

The Jessica 800 Pocket Support Mattress is available in a medium firm tension with an impressive pocket spring support layer. With 800 springs in the unit, you will be able to fully appreciate the body contouring on offer.

The pocket sprung version uses 800 individual pocket springs which are constructed from a combination of steel, offering the best of both worlds by combining the bounce of traditional springs and the body contouring and edge to edge support of a good quality and supportive base.

This mattress is designed to be used on top of a base, such as a divan bed or wooden slatted bed base. To ensure your mattress stays in good condition for as long as possible, we'd also recommend regular rotation between head and foot end every few months.

The Jessica is hypoallergenic which is great for people who suffer from allergies and is ideal for those who need to get a good night's sleep who suffer from allergies or asthma.

This mattress is available in any size, including Small Single (3ft), Small Double (4ft6), Double (5ft), King Size (5ft), Super King Size (6ft).

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.

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.

Features 800 traditional pocket springs for total support

This mattress is designed to provide the perfect balance between support and comfort. It features 800 custom pocket springs to provide the ideal level of bounce back for your weight. This allows you to sleep comfortably with full body contouring that outperforms poorer quality support layers.

Foam encapsulated for reinforced support and maximum amount of sleeping space!

A Platinum Breathable™ layer to help regulate body temperature

A mattress that is breathable allows air to circulate through it, keeping you cool and comfortable as you sleep. Many mattresses are made with materials that trap heat, causing you to wake up hot and sweaty. A breathable mattress helps you stay cooler and can promote a deeper, more restful sleep.

Has a firmness of medium-firm for the best balance of comfort and support

A medium to firm mattress tension sees the softness of a medium tension decreased slightly to offer better back and neck support without sacrificing too much in terms of comfort. Better suited toward back or stomach sleepers, this mattress may be a bit too firm for side sleepers who have protruding hips and shoulders that would otherwise dig into the support layer. For everyone else though, this mattress offers a great degree of comfort and support that will leave you waking up feeling refreshed.

All wrapped up in a beautifully designed, quilted and knitted cover

This mattress comes with a quilted cover. Many people overlook the cover as a need for consideration however, the right cover can add additional comfort and in the case of this one here, adds quilted comfort that offers a soft but hard-wearing cover that is both breathable and stylish.

Hypoallergenic for a cleaner, healthier sleep

Hypoallergenic mattresses are unlikely to cause allergies due to the materials involved, while the mattresses are not guaranteed to cause no reactions, they are the closest you will come with an off-the-shelf product toward preventing allergies.

It’s single sided - all you need to do is rotate it using the built-in, sturdy turning handles

Single sided mattresses typically offer great value at a slightly lower price point than their double sided alternatives. The benefit for you is that you won't need to flip your mattress although you will still need to rotate in line with manufacturer guidelines. 

100% recyclable and vegan-friendly

A product that is 100% recyclable is considered better for the environment and goes a long way to reducing your personal waste. Recyclable products and materials are able to be repackaged and remade into new products.

Mattress 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.

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.

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.


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


The fabrics, materials and fillings of this mattress are the result of what has been deemed vegan-friendly materials. Ideal for those expressing their beliefs while still requiring good levels of comfort and support from a product

Medium to Firm

Firmer than the average mattress, a medium to firm mattress is ideally suited to those that are looking for extra back support but still require and amount of comfort from their mattress. Ideally suited for a large range of the populus and becoming much more common, deviating away from the previous medium-for-everyone model.

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.


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

Customer Reviews For The Sleepeezee Jessica 800 Pocket Support Mattress

Based on 5 reviews

A very well made mattress that's firm but has a slightly soft top. The sides are firm too, so they don't sink down when you sit on the side, I'm very happy with it. It is very firm though, so I did experience some back pain until I bought a mattress topper. Just thought I'd mention this if someone else is considering purchasing this particular mattress. Beautifully made with lovely materials, I think it'll last for quite a few years.


Love my new mattress, right balance with comfort and support. Clearly well made high quality mattress.My last sleepezee bed lasted over 10 years, no reason to think this one won't do the same!


Supportive mattress, firm and great for a good night sleep and good posture, no aches or pains.
