When it comes to investing in your sleep, the right mattress can make all the difference. Enter the Simba Natural Hybrid Source Mattress (formerly the Simba Earth Source 2900 Wool Mattress) - a concoction of expert craftsmanship, premium materials, and clever design. Underneath the name sit a pocket spring unit, a layer of mini springs and British wool, all in a 28cm single-sided mattress.
How we assessed it
The support comes from 1000 CoreMax pocket springs, zoned so that each area responds to the weight on it and leaves the rest alone. Above them sit 1900 Aerocoil mini springs, conical so they can compress fully and bounce back, then layers of wool. On paper that points to a firm, level mattress with little roll-together, and owners agree: one wrote that "the pockets springs prevent roll together and bounce". Wool breathes better than foam, so we'd expect it to sleep cooler than a foam hybrid. Several owners who swapped from a foam mattress say so, though one found it held the heat better than their old mattress and moved to a lighter duvet.
Design and Features
The Simba Natural Hybrid Source Mattress comes equipped with an array of quality features promising a good, restful sleep. Encased in cloth pockets, the mattress hosts an ample density of pocket springs, with each spring individually adapting to your body's movement. This ensures a personalised sleeping experience, with the mattress tailoring its support to different parts of your body.
Taking comfort up a notch, mini pocket springs embedded within this mattress provide added comfort. These tiny titans of comfort work diligently to reduce motion transfer - an invaluable reassurance if you tend to share your bed.
Adding to this is the very plush wool layer. A dream for those who love to snuggle into their beds, wool, a natural insulator, promises year-round comfort. Its temperature regulating properties keep you warm on cooler nights, whilst helping to keep overheating at bay when the mercury rises: wool worn next to the skin has been shown to improve sleep even at 30°C.1
Ignore the toilsome task of flipping your mattress, as the Simba Natural Hybrid Source is single-sided, designed for convenience. All you need to do is rotate it every few months, and you are good to go!
Mattress Comfort
Owners put the Simba Natural Hybrid Source at the firm end of its medium to firm label. One summed it up as "a bit harder than expected but it's superb", and plenty say they wake with less back ache than on their old mattress. Not everyone gets on with it. One owner who sleeps mainly on their side found it "a bit shoulder crunchy for me on my side", and for another it was a "Very hard mattress" that hurt their back and shoulders.
However, do bear in mind that comfort is subjective and very much depends on personal preferences and sleeping habits. The medium-to-firm discomfort might not gel well with side sleepers who prefer a surface pliant enough to cradle their pressure points. But it's a thumbs up for back and stomach sleepers who crave a bit more rigid support. Simba's Natural Hybrid Source mattress provides the desired firmness while its top wool layer adds a gentle sink-in feeling, preserving the cushiony snugness.
Suitability
As for suitability, a medium-to-firm build like this should strike the right chord mainly with non-side sleepers of average weights. But those who favour sleeping on their backs might need to pause and reflect since the mattress' support layer leans more towards firm.
What Customers Thought
Customer reviews play an integral part in purchasing decisions, providing us with valuable insights about a product's performance in diverse user scenarios. The available reviews for the Simba Natural Hybrid Source seem to echo similar sentiments. Most users were thrilled with the value that the mattress brought to their sleep experience. They were particularly enamoured by the spring segments' ability to minimise partner disturbance and provide fine-tuned, individualised support.
The verdict
The Simba Natural Hybrid Source Mattress has of significant strengths like a supportive spring system, comforting wool layer, user-friendly single-side construction, and superb temperature regulation. However, it does stumble a little when it comes to suiting all sleeper types. Some consumers also pointed out the potential for compression over time, despite the impressive pocket and mini spring configuration. The 28cm depth may be a concern when pairing it with standard bedding, and its thermal regulation performance could still leave some sleepers feeling too warm for comfort.
Despite these minor points of caution, we think the Simba Natural Hybrid Source Mattress is a promising player in the sleep-improving arena. Like all purchases, it's important for you to weigh up its characteristics against your personal preferences and needs. But all things considered, this mattress is a potential standout feature in taking a step towards better sleep health.
