Mattress Performance Test

1. Pressure Relief

simba mattress pressure review

The Simba mattress is said to provide excellent pressure relief and our tests showed that this is true. Thanks to the small, conically shaped springs in the second layer of this mattress, together with the two foam layers - of which the second one has 7 support zones - this mattress helps relieve pressure in any sleeping position that you may prefer.

PositionResults
• Side SleepersSide sleepers should feel minimal added pressure on the hips or shoulders.
• Back SleepersBack sleepers can often feel that their hip section sinks too deep into the mattress. The mix of layers helps support this region of the body.
• Front/ Stomach Sleepers➮ Same as for the back sleepers, front sleepers should not feel any lack of support in their mid-section and no added pressure either. This position can however be compromised with heavier individuals.

2. Temperature Regulation

simba mattress temperature control

There are a few elements in this mattress that help improve temperature regulation. The presence of springs, although very small ones, help to add more airflow to the mattress, as do the zoned parts of the foam.

The covers structure seems to also help with dissipating heat. Our tests showed that the majority of heat would disperse rather quickly, making this a decent cooling mattress option.

3. Spinal Alignment

simba mattress spinal alignment

Mattresses for bad backs typically achieve a great balance between comfort and support. The base layer of the Simba Mattressis a high-density foam layer with 7 zones to help support your body where needed as well as providing pressure relief on critical areas. This will help to align the sleeper’s spine and thus help to prevent future possible back problems.

The results we got when testing for spinal alignment are very good and what seems to be the average among boxed mattresses.

4. Motion Isolation

When looking for a mattress for couples, motion transfer can be problematic if you are sleeping next to a restless partner. All-foam mattresses tend to be better at motion isolation than spring or hybrid mattresses but this hybrid model still showed decent results. Motion was detected on one side when bouncing heavily on the other.

5. Edge Support

When testing for edge support in a mattress we measure two things: sitting on the inner side of the edge and sitting on the very edge of the mattress.

The Simba mattress showed great results for edge support when sitting comfortably on the inner part of the edge and above average when sitting on the outer edge of the mattress. Many memory foam mattresses give way at the outer edge however the Simba Mattress has decent support.

Simba Mattress Firmness 

Firmness is very subjective. What you may consider firm another person may not. There are many factors affecting one's sensitivity to the overall firmness of a mattress.

Therefore one has to take into account the firmness rating from Simba themselves as a point of reference. They score it a 6.5 out of 10 on the firmness scale. By creating a medium feel mattress Simba hoped to meet most of the sleeper's needs in the UK. 

If you are one of those that tend to lean to the ends of the spectrum we would highly suggest you do your research on some of the best soft and firm mattresses.

The combination of the Simba-Pure top layer and the base layer helps give the mattress a comfortable and responsive feel. Yet still designed to be supportive enough to balance out your bodyweight evenly. The castellated base also helps to comfort the extruding areas of your body, especially for side sleepers. 

Simba Mattress Construction & Certifications

The Simba Hybrid mattress as its name suggests combines the comfortability of foams as well as the bounce of conical pocket springs.

Mattresses that harness the benefits of both pocket springs and memory foam are referred to as "Hybrid Mattresses". These have been very popular and are generally marketed as a novel item or a mattress that utilises the latest technologies.

The foams used in the Simba Mattress all received the CertiPUR label, which makes them suitable and safe to use for everyone. This label ensures that no unwanted harmful chemicals are used in the foams.

The Simba Mattress uses foam called "Simba-Pure" which has been developed without the use of 'TCPP'. TCPP is a flame retardant used in foams as early as the 1960’s this has, of course, increased in the UK since the introduction of the Furniture and Furnishings Fire Safety Regulations in 1988.

Besides TCPP, the foam is also free of bisphenols and parabens✓. Additionally, Simba state you shouldn't get that chemical smell when receiving new mattresses, also known as "off-gassing".

The mattress is produced here in Europe, sourcing materials from the UK and Poland. What’s also worth noting is that Simba’s manufacturer is a national bed federation approved member. A major role of the NBF is that of education of both the trade and consumers.

Simba has put a huge emphasis on mattress testing and in creating the ultimate mattress to suit almost all types of sleepers, take a look to what extent Simba has invested in creating their well-known Simba Mattress.

They have studied 180 million body profile measures taken from just about 10 million sleepers. Things taken into account were, height, weight, gender, pressure points, flexibility and even weight distribution. Covering almost all there is to cover. This involved comparing Simba Sleep’s data to The Sleep to Live Institute’s “databank” of over 10 million body profiles. which had been gathered using Kingsdown’s patented BedMatch system, according to an Advertising Standards Authority Ruling✓.

Simba has said to have built over 70 prototypes in order to create a hybrid that would suit the majority of the population here in the UK.

Simba Mattress Layers 

simba sleep layers
  1. Top Comfort Layer - This is known as the Simba-Pure layer. It an Open-Cell polyfoam layer. Open-cell polyfoam is known to be superior to regular polyurethane foam as a top layer as it allows for more air to freely flow through it making the layer non-heat retentive. Additionally, Simba has included graphite in this layer. According to a study✓, Mesophase pitch-derived open-cell graphite foams with excellent heat transfer properties have been developed by using a relatively simple manufacturing technique. Which suggests that graphite foam could be better at transferring heat than regular foams.
  2. Conical Pocket Spring Layer - The positioning of this layer beneath the top comfort layer is well planned. The springs are made to provide bounce and responsiveness to the sleeper as well as balancing out pressure disparities. The coils are enclosed in polyester pockets to keep them always facing upright and to protect the surrounding foams. The springs are conical means they have a cone-like shape and allow the spring to collapse to a height of the actual wire. Which is very important as the layer is not that thick. A king size mattress will have about 2,500 unique conical pocket springs (based on Simba Hybrid Original mattress). The titanium alloy✓ used is 100% British and manufactured in Leeds.
  3. High Definition Foam Layer - This layer acts as a transition layer between the foundation and the springs. Before memory foam was used but as memory foam is known to be heat retentive, Simba has decided to include a polyurethane-based foam for support which does not attain as much heat. Simba has also introduced "edge lift technology" as Simba calls it. That way you receive great support from edge to edge.
  4. Base Foam - This is the foundation of the Simba hybrid mattress. The supportive base layer is from high-density polyurethane foam. This layer has 7 different zones for support. These areas have grooves cut out to allow for more give in areas such as the hips and shoulders (also known as castellated). This helps to ensure correct spinal alignment. The grooves also help with airflow and hygiene.

Simba Mattress Cover 

With up to 700g light hand-knitted top cover (white half) is from 100% polyester to give it a stretchy feel. The cover now also includes 4 mattress handles which make it very practical in case you will need to move it.

Unfortunately, The cover is not removable or washable. The bottom half can be cleaned by using a damp cloth and rubbed in a circular motion. We would recommend using a mattress protector to keep your Simba Mattress clean.

The cover is made without any harmful chemicals and is said to be 'hypoallergenic', this term is used to describe textiles that cause or are claimed to cause fewer allergic reactions.  

How Thick Is the Simba Mattress?

simba mattress thickness

The Simba Mattress has a total depth of around 25,this means your current standard bedsheets should fit.

The mattress can also hold up to 18 stone or 114kg per person. We have a whole list of mattresses and their total limit if you are specifically looking for a mattress that can support heavier people.

Simba Mattress Trial Period and Warranty  

Simba offers a 200-night trial on all of their mattresses. Simply put, this means you can return it for whatever reason within 200 days from delivery.

This is amongst the most generous trial periods we have noticed from doing a whole post on the different types of mattresses with trials.

Simba’s reasoning behind this is that you experience the perfect nights’ sleep so you don’t need to keep the mattress wrapped in the plastic cover, just use like you normally would.

We’re confident it’ll be love at first night - but we give you 200 to be sure. If you decide to return your Simba, we’ll collect it for free (and don’t worry, we wouldn’t dream of asking you to get it back in the box).

If you feel the Simba hybrid mattress is not for you, simply give Simba a call or send an email to arrange a pickup. 

A courier will be sent over to remove the mattress from your home and donate it to a local charity or recycling centre whenever possible. You’ll then be refunded the full value of your order. 

 A 10-year warranty on each Simba Mattress ensures security in the long run and validates the mattresses test of time.  

Simba Mattress Delivery   

Your Simba Mattress, whatever the size, should be delivered in a convenient box within 1-3 business days. Simba deliver to the whole of the UK, this includes Scotland, Wales and offshore addresses.  

UPS or DPD is used as the standard free delivery service. Tracking is received about 24-48 hours before delivery. We did some undercover work for this Simba hybrid mattress review and found out all UPS deliveries are door-to-door service.

If delivery is missed, they will leave a calling card and re-attempt delivery on the next 2 business days (3 attempts in total).

Because of growing concern over safety, many bed in a box companies are now offering a ZERO contact delivery which Simba has also committed to.
