Simba Mattress | The Ultimate Evaluation

Simba mattress UK claims its mattresses are the best thing since sliced bread – with the most five-star reviewed mattresses globally that come with a simple, no-hassle 10-year guarantee ensuring a replacement if it falters in that time.

So why are so many Simba customers contacting Winstons Beds to complain that their Simba mattress has formed an indentation right down the middle or notable body impressions, leaving them with restless nights?

The most concerning point is that the consumers allege Simba Sleep refuses to honour its guarantee, using “independent inspectors” to visit the customer’s home and report that the defects are not significant enough to claim a replacement.

Simba mattresses do not come cheap – their top-selling kingsize mattress is priced around £600 – and the online reviews are undoubtedly excellent. Nevertheless, if you take a look closer, a different view soon emerges. Consumers are offered the chance to gain back the cost of the mattress if they are prepared to leave a post-purchase review – which means many of the reviews you are reading are written before any problems emerge.

A number of those who contacted Winstons Beds say that they feel as though Simba has mistreated them. The consumers paid £699 for their king size mattresses, and within a year of use, the mattress developed an indentation right down the middle and body impressions on either side, which drove them into the guest room to get a good night’s sleep.

An article from Guardian Money has advised that they receive a complaint about a Simba mattress every four to six weeks and that Simba had stated they will now review these complaints. However, Simba has sold over 350,000 mattresses, so this issue of indents and impressions may only affect a fraction of their customers.

What is Viscogel?

Viscogel is memory foam infused with graphene, effectively promoting cool temperatures and higher quality sleep. In addition, Viscogel ensures full-body support and mattress durability.

What is Polyurethane Foam or Simba Open Cell Pure Foam?

Simba Open Cell Pure Foam or Polyurethane Foam is a cooling foam that has an open-cell structure which keeps you cool by using graphite particles.

What is the difference between Winstons Micro Pocket Springs and Simba’s Micro Conical Pocket Springs?

Conical springs collapse further than non-conical springs meaning a conical spring will give the mattress a little more bounce. At Winston’s, we prefer to construct the mattress with a 250GSM layer of Wool, Cashmere & Silk as the top layer, 5cm ViscoGel as 2nd layer, and 2.5cm Neuform Memory Foam as the 3rd layer to give the mattress more give and bounce than conical springs can achieve.

Why do Winstons use graphene and what is it?

Graphene is bonded carbon atoms in a honeycomb lattice structure and is one of the most abundant elements on the earth and vital for life. It is one of three naturally occurring forms of carbon found in metamorphic rock and a common mineral consisting of hundreds of thousands of layers.

Why do I want graphene in my mattress?

Graphene has revolutionary attributes that make it a miracle material used in many applications in the electronics, medicine, food, sports and energy industries.

It has now found its way to consumer goods, including innovative uses in foams that offer some exceptional benefits to mattresses and sleep.

Here are the ways graphene in your mattress will improve your sleep:

Thermal conductivity

• Graphene’s thermal conductivity makes it effective in heat dissipation by carrying heat away from the body to maintain a comfortable temperature throughout the night.

Electric conductivity

• Carbon’s natural electric conductivity enables carbon fibres in a mattress to assist the body discharge accumulated static charge, which promotes a night of deeper and more rejuvenating sleep.

Antibacterial

• Graphene has antibacterial properties with strong cytotoxicity to bacteria, which means it will eliminate bacteria.

We compared the Simba mattress range against 5 others, including mattresses from Emma Mattress, Eve Mattress, Ergoflex Mattress, Brook and Wilde Mattress and the coming soon Winstons No1 Hybrid bed in a box mattress.

You’re likely to have seen advertisements for Simba mattresses, ensuring ‘gravity-defying comfort’ and ‘cooler sleep’ due to its five layers, which incorporate a mixture of springs and memory foam.

At £650.46 for a Simba double mattress, currently reduced from £879, the Simba Hybrid is relatively cheap among its online rivals except when compared against the Winstons No1 Hybrid. Nonetheless, we believe the Simba mattress will support your back for many years and is best suited to back sleepers from 10-16 stones and side or front sleepers who weigh from 11-18 stones.

Mattress Firmness relates to how firm or soft a mattress will feel. Bed in box companies state their mattress will suit any sleeper up to a certain weight which is generally 28 stones. We believe this to be utterly false as most if not all bed in a box mattresses are medium-firm comfort grades; therefore, they will only be suitable for specific types of sleepers and weight groups.

We use a weight and sleeping position-based table referenced from medical blogs to help convey if a medium-firm bed in a box mattress is right for you.

The Hybrid is Simba Sleeps best selling mattress. It’s made up of 5 layers: A 16cm (6.3 inches) foam core with a micro pocket-spring layer between two layers of foam, topped with a 2.5cm layer of foam. It’s a bed in a box mattress, so it’s delivered roll-packed in a box to your front door with a 10-year guarantee and 200-night trial. If you decide the mattress is not for you and you choose to return it, Simba offers a hassle-free return.

Simba currently has three mattresses in its bed in a box collection, and we have purchased and tested all three.
