Are Simba mattresses worth it? This is our experts' honest review

Score: 89/100

This is Simba’s original hybrid mattress, and according to our testers, the medium-firm design is still its best. Everyone praised the delivery and unboxing process.

Come bedtime, our testers loved the way its 2,500-odd springs and unique foam combine to offer support while contouring to the body with a cloud-like sink-in feel. For some, it also eased pre-existing aches and pains.

It was quiet when our testers moved during the night, and for most people, it regulated their body temperature well. You can even zip off its cover to wash it and keep things fresh.

As with our reader feedback, the odd tester noticed a dip forming over time, but this wouldn't stop them recommending it to others, with one reviewer telling us: “I'm sleeping a lot better since it's been in my life!”

This was a big hit with our testers. As its name suggests, it’s one of the brand's more premium designs and when you hear what’s inside its washable cover, you can see why. There are 11 different layers, including a total of 6,000 springs, as well as Simba’s foam tech, and a wool and bamboo layer for added breathability.

At nighttime, it was comfortable, supportive and quiet when anyone moved around, thanks to the edge-to-edge support. Impressively for a mattress with foam in, its temperature regulating claims proved true, even for testers who run hot at night: “I used to lose sleep overheating at night and couldn't settle,” one told us, “but this mattress has transformed my sleep, so I can go about my day to day feeling less stressed.”

Again, it's a medium-firm mattress, so if you like a firm finish it may be a little too soft (it was for one tester), and like the Hybrid, you should rotate it as per the brand’s instructions to avoid any dips forming. You may also need to buy deeper sheets.

But our panel loved it on the whole. “It’s very hard to get out of bed in the morning, it’s so comfortable!” said one. Which is just the level of cosiness we dream of in a mattress.

This is the priciest mattress in Simba's natural fibre Earth range, complete with luxurious cashmere and mohair layers and a whopping 6,700 springs. From the very first night, it wowed testers with its hotel-quality plushness, tailored support and temperature-regulating capabilities.

The medium firm mattress is suited to a range of sleepers, and was particularly popular for easing aches and pains. One tester even said it helped with their insomnia, saying it was like “sleeping on a cloud.”

The Simba Earth Apex is a notably deep and weighty mattress. It provides luxurious support, but it does require deep-fitted sheets (and perhaps a second person to help with regular rotation). It sprang back into shape each morning with ease, and no dips, sagging or soft spots were detected during testing.

There’s no denying that the Earth Apex sits at the luxury end of the mattress market, but with its plant-friendly natural layers, advanced spring support system and 10-year guarantee, the majority of testers felt it was a worthy investment (after all, you can’t put a price on better Zs).

Score: 85/100

Also part of Simba's Earth range, the Source mattress is a more affordable option, with 2,900 springs and fewer layers. Still, it won over even the fussiest of sleepers in our tests.

Striking a balance between plush and firm, it comfortably cushioned pressure points and eased aches, with one sciatica sufferer saying they’re now able to sleep soundly through the night – no mean feat. For those sharing a bed, it isolated movement, leaving even the lightest sleepers free from wriggle worries.

Style-wise, it looks and feels premium. But it is deep so you may need to invest in new sheets. Unboxing was mostly smooth sailing; however, some panellists were left hunting online for set-up instructions, and a few noticed a scent that lingered for up to two weeks. This wasn’t an issue for everyone, but it’s worth bearing in mind if you’re sensitive to smells.

For a mattress that’s kind to your back and the planet, our panel felt it earned its price tag. Smartly designed, sustainably made, and seriously comfortable, it’s an instant upgrade to your sleep set-up.

The Simba Hybrid Ultra has 8,500 springs, the most of any mattress we’ve tested. There are also 13 different layers to this design, including four spring layers, cushioning foam, and a cooling combination of wool, bamboo, charcoal and kapok (an airy plant fibre with a natural wax coating that makes it moisture resistant).

All this doesn’t come cheap, but rest assured you won’t feel a pea through all those layers; everyone who tried this mattress found it comfortable to sleep on. It ticked the boxes for support (easing back ache for some), temperature regulation, stability and quietness. No dips formed over the testing period either, and everyone would recommend it to friends and family.

However, it is heavy, which our testers marked it down for as they struggled to get it into position. This also makes the required rotation harder, and you’ll definitely need to invest in deep sheets.

But if you can enlist a second pair of hands to help you move it, and you have the budget, it’s a standout buy. As one tester said: "This mattress is wonderful! It's just so comfy; I can't wait to lie on it every evening."

Positioned between Simba’s Hybrid mattress and its Luxe offering, this is a good Goldilocks buy. It has eight different layers of foam, springs (there are 5,000 of them!) and more, with testers finding it a reliable temperature regulator thanks to the layer of cooling British wool. They also found it sturdy, supportive and, most importantly, comfortable.

It had a slight memory foam smell, but this dissipated within a couple of days. Again, some noted slight dipping over time, but this didn’t impact its overall comfort.

This is another all-rounder from the brand that provided quality shuteye for our testers. We appreciate it may be tricky to decide on the right design for you. When weighing up your options, we suggest deciding on the features that interest you the most (natural fabrics, cooling capabilities etc.) and seeing what you can get for your budget.

This more budget option has four layers, including a washable cover, 1,000 springs, a foam base and a top layer. As you’d expect then, it doesn’t quite provide the same hotel-level comfort as some of the others on this list – some testers loved the support it offered, while others found it wasn't quite right.

But our panellists found it temperature-regulating and told us it was stable and quiet when partners moved at night. A dip started forming for one tester, but everyone else praised its quality.

Those who loved it said they wouldn't hesitate to recommend it, with one telling us they felt “super rested in the morning” and would keep using it. If you need a precise level of support however, we’d suggest investing in something more premium.

Score: 79/100

The final mattress in Simba’s Earth range, this medium firm design – which blends premium all-natural materials with advanced tech – is designed to help you “escape the stresses of the day”. It’s 30cm deep and comprises 10 layers, including British wool for next-level comfort and superior temperature regulation. The CoreMax sprung base is designed to minimise motion transfer and the two Aerocoil spring layers provide extra support and pressure relief.

Our panellists rated the durable, sturdy design, noting that it felt well-made with no signs of damage or dipping after six weeks of testing. They were able to use their standard sheets – no need to invest in new ones – and they liked that it didn’t have a strong smell on arrival. It did a good job of regulating their temperature overnight and the majority of testers said the medium-firm design provided ample support and cushioning, too. It was also quiet when they moved around.
