Simba Hybrid Pro mattress review in brief
- Impressive 4,800 springs in its 8-layer hybrid structure
- Simbatex foam promotes airflow
- Average motion isolation
There’s a host of excellent value medium-firm mattresses in the Tom’s Guide best mattress edit, and the Simba Hybrid Pro stands out for its comfort, good pressure relief and cushioned support.
The best-selling Simba Hybrid Pro is a great all-rounder that features a supportively medium-firm base layer with a plush and breathable comfort layer on top. With eight layers of micro springs and cooling Simbatex foam within its 28cm (11-inch) thick structure, it’s Simba’s best-selling mattress. With its natural wool comfort layer, it feels a little plusher but just as supportive as the classic Simba Hybrid.

As a well-respected bed-in-a-box brand, Simba has a host of hybrid mattresses in its online range available for delivery in the UK, some European countries and launching soon in the USA. The Simba Hybrid Pro comes with a middle of the range price tag and medium-firm support, but there are multiple options to choose from in Simba’s collection.
The Simba Hybrid Ultra Mattress is a design that costs considerably more than the Hybrid Pro, but which offers a more luxurious offering of support and springs, for example. There’s also the more budget-friendly Simba Hybrid Mattress and the entry-level Simba Essential that are also great value and feature Simba’s graphite infused Simbatex foam that provides comfort and cooling.
While testing the Simba Hybrid Pro in late autumn, I found this mattress reliably provided a peaceful night’s sleep. This is due to its luxuriously thick 28cm frame that features a CertiPur stability layer, a removable cool-touch cover and double titanium alloy Aerocoil spring layers. It’s the kind of mattress that looks and feels like it’s designed to stand the test of time and, to date, it has done a good job at maintaining its promise of offering optimal support, pressure relief and cooling.
I’ve reviewed its design and performance here in detail and highlighted its edge support, motion isolation and ability at providing good pressure relief. While it didn’t perform as well as in my motion isolation tests, I was impressed with its overall performance and mark it out as a reliable buy for side and back sleepers in particular.
Simba Hybrid Pro mattress review: price & deals
- A mid-range mattress in the Simba lineup
- Comes with a 200-night trial (UK) 100 night trial (USA)
- Includes a 10-year warranty
In this review I’ve tested the UK version of the Simba Hybrid Pro, which is Simba’s mid-range mattress and current best-seller with very impressive specs.
You’ll currently pay full price for the Hybrid Pro. However, that does come with a free pillow, duvet and mattress protector included. But if you time it right, you could it reduced by up to 25% in the Simba mattress sales. (You’ll most likely see the best discounts at peak sales times such as Black Friday and Cyber Monday).
The mattress comes in seven sizes with the current pricing as follows:
- Single (UK): £799 (£599.25 on sale)
- Small Double (UK): £1,199 (£899.25 on sale)
- Double (UK): £1,199 (£899.25 on sale)
- EU Double (UK): £1,199 (£899.25 on sale)
- EU Queen (UK): £1,299 (£974.25 on sale)
- King (UK): £1,299 (£974.25 on sale)
- Super King (UK): £1,399 (£1,049.25 on sale)
If you can’t pay the full price upfront, you can spread the cost with Simba’s finance options. For a single you would pay £15.84 monthly based on 48 monthly instalments, for example.
When you click to buy your mattress, Simba offers several add-ons to enhance your mattress. You can choose from accessories such a Simba Performance Mattress Protector, from £79.20, or a Simba Hybrid Pillow (from £109) and Simba Hybrid Duvet (from £139 for a single). Each mattress purchased comes with a 200-night sleep trial and 10-year warranty for peace of mind.

Simba Hybrid Pro mattress review: materials
A step up from the Simba Hybrid in terms of price, comfort and thickness, the Pro has eight layers of foam and springs in its 28cm frame. It features a Supportcore Spring base, a wool top layer, Simbatex cushioning foam, a CertiPur foam base layer and a zip-off breathable cover that can be machine washed.
Simba Hybrid Pro mattress review: firmness & comfort
- 4,800 springs and Simbatex foam create a medium-firm feel
- Aerocoil micro springs for minimum movement and uninterrupted sleep
- Simbatex foam claims to have five times more airflow than memory foam
As Simba’s bestselling design, the Simba Hybrid Pro comprises eight layers and is firmer than the brand’s classic Hybrid, but comes with a a more plush top wool layer.
The Hybrid Pro features a ‘Stratos cool-touch’ removable cover that features a natural wool layer and breathable graphite infused Simbatex foam so you get cushioning without feeling too hot.
Beneath this, Aerocoil micro spring layers compress individually to offer support and provide pressure relief in key areas such as the hips and shoulders while limiting movement from side to side. 1,000 pocketed tempered steel barrel springs and core foam layers ensure the base is secure so there’s no risk of rolling off and the mattress feels stable.
As a side and back sleeper who switches positions in the night and favours a medium-firm mattress over a very firm one, I enjoyed sleeping on this mattress. I found that it offered the support and reliability of a firm mattress, disguised beneath a plush and welcoming top layer. I share the bed with my front-sleeping partner who often starts on his side and ends up on his front and prefers firm support. He agreed that the mattress provided a nice mix of cushioning comfort while making him feel well supported.
It took me a few nights to get used to the feel of the cushioned top layer, but after a week of sleeping on this mattress all thoughts of previous favourite mattresses had disappeared. My partner was not as convinced, however. While he found it comfortable he would prefer a firmer mattress long-term.
Simba Hybrid Pro mattress review: performance
- Plush top layer with good pressure relief
- Acceptable motion isolation
- Excellent stability and good side support
I trialled a king size version of Simba Hybrid Pro over a wooden slatted bed frame for three months during the autumn months. I tested its performance, motion isolation, edge support, cooling and ease of setup.
It’s hard to tell how the mattress will fare over time, but we will report back on longevity further down the line. But with its soft and tactile materials and visibly good-quality stitching, it looks like a design that’s built to withstand its promise of comfort. And if not, there’s always Simba’s 10-year guarantee and 200-night trial to fall back on.
Setup
The king size version Simba Hybrid Pro weighs around about 49kg (108lb) once unpacked. Simba mattresses can be heavy and the Hybrid Pro will need two people to carry and rotate. It’s not as heavy as the Simba Hybrid Ultra, however, which is the brand’s most premium design weighing 50kg (110lb) for a king size.
The weight of the Simba Hybrid Pro does, however, give it that air of luxury normally associated with premium pocket sprung mattresses. The mattress comes rolled up and vacuum-packed in plastic packaging to make it easier to deliver. Once it had been put in place on my bedframe by the delivery team, I was able to slice open the plastic packaging and allow the mattress to take shape.
It wasn’t until around four hours after opening it from its vacuum-packed roll that the Simba mattress looked formed enough to sleep on. But for the mattress to fill out completely so that the sides feel sturdy and its cover doesn’t look saggy, it’s best to wait up to 72 hours.
Score: 4 out of 5
Off-gassing
Luckily, Simba mattresses don’t seem to suffer from this problem and like both the Simba Hybrid and Simba Hybrid Ultra that I’ve tested in the past, the Simba Hybrid Pro had very limited off-gassing that disappeared within a day of opening.
Score: 5 out of 5
Pressure relief
Effective pressure relief is integral to the quality and design of a good mattress and will make all the difference to comfort. With good pressure relief you’ll be supported in all the right places so that your shoulders, hips and lower back to gently sink into the mattress while keeping the rest of your body supported.
While this mattress has a good amount of cushioning at its top layer, it has a firm and stable base with ‘SupportCore’ springs that cradle the body and this is what kept both myself and my partner feeling well supported.
The cushioning takes a bit of getting used to, and while it does feel a little squishy, there’s a definite firmness underneath so I didn’t feel like I was ever sinking in.
I used an 8kg kettlebell and measured the sinkage of this mattress just under 5cm (2″), which is about average for a medium firm mattress. In comparison, I measured the sinkage of the tall and lofty Simba Hybrid Ultra at 3.8cm (1.5″).
Score: 4 out of 5
Motion transfer
Mattress companies have upped their game in recent years to improve motion transfer technology and Simba’s designs tend to score high marks in this area. Good motion transfer technology is important as having your mattress wobble when you get in and out or if your partner changes sleep positions at night is no fun.
Simba Hybrid Pro is designed with Aerocoil microsprings to help reduce movement through the mattress. The springs – along with a wool top layer – help to give the mattress a cloud-like feel, but they compress individually and respond separately to reduce disturbance from side to side.
Overall, I found that the mattress did well to limit movement across its surface, which came as a surprise as I was expecting the softer top layer to make the mattress less stable. Both myself and my partner managed to get a good night’s sleep. And on most occasions, we didn’t get disturbed by the other when turning or switching positions at night.
I also tested the motion transfer technology using a 3kg weight and empty wine glass to simulate someone getting in and out of bed. I dropped the weight 25” away and 10” away where the glass stayed put. At 4”, it buckled, however, which proves that while the motion transfer technology is good here, it’s not the best we’ve seen.
Score: 4 out of 5
Temperature regulation
There are various ways in which the Simba Hybrid Pro mattress keeps its cool. The knitted polyester cover has a distinctive diamond stitching and features a breathable wool layer. The mattress also has a layer of open structure graphite-infused Simbatex foam to encourage air flow and is proven to provide five times more airflow than standard memory foam. The breathability is enhanced by the Aerocoil microsprings that compress individually and push fresh air upwards to make you feel cooler.
I tested this mattress at the end of autumn when the balmy weather was fading and the room temperature never went above 20°C (68°F). During the testing period I used a Simba Hybrid 3-in-1 Duvet that seemed to complement the mattress well to keep me at a comfortable temperature all night long.
Score: 4 out of 5
Edge support
It’s refreshing when you find a mattress with good edge support as this is a feature that’s so important for overall comfort as you sleep. Good edge support not only gives you maximum sleep surface, but it ensures a more comfortable fit when getting in and out of bed. It also makes it easier to change the bed sheets and ensure fitted sheets sit more securely.
While testing this mattress I found the edge support good. The corners of the mattress weren’t quite as stable as the sides, but overall the mattress felt stable from edge to edge and secure enough so that I could sit on the side without slumping.
Score: 4 out of 5
Durability
Three months later I’m still impressed with the Simba Hybrid Pro. It’s a mattress that holds its shape well without sagging like some designs can. It feels stable and sits nicely on the bedframe, it’s easy to rotate every now and then to keep it in shape and, most importantly, it feels reliably comfortable.
I’ll be interested to see how well it fares in a year’s time, but so far so good. And if there are any issues, there’s always the 10-year warranty to fall back on.

Simba Hybrid Pro mattress review: user reviews
The Simba Hybrid Pro is an award-winning mattress that has plenty of positive reviews. At the time of writing it has a score of 4.8 out of 5 on the Simba website, based on over 36,000 reviews, with customers praising its comfort, support, motion isolation and temperature regulation, with many noting that sleeping on the Hybrid Pro had resulted in reduced aches and pains.
Should you buy the Simba Hybrid Pro mattress?
Having slept on the Simba Hybrid Pro for three months, I think it’s great option for side and back sleepers looking for a blend of sink-in pressure relief, underpinned by sturdy support. That means that means that while the touch points of the mattress are cradled, your spine will be held in healthy alignment with the rest of your body (that’s good news for anyone with back pain).
While I think it’s best suited to side and back sleepers, it’s also comfortable for average weight stomach sleepers too. (For heavier back and stomach sleepers, you will likely require something firmer.)
There’s no getting away from the fact that with a King costing £1,299 at full price, the Simba Hybrid Pro is expensive. However, it’s a premium hybrid mattress that does everything well; temperature regulation is reliable, motion isolation is great and it’s comfortable from night one.
Still, if you’re looking for a cheaper alternative, you’ll find my suggestions below.
