15. How we test

For a rested night's sleep, you need to upgrade to the best mattress of 2023. If you don't know where to start, T3 are here to help as we've tested out a wide range of mattresses to find the ones that deliver the most comfortable and supportive sleep. This comprehensive best mattress guide UK will help you find the perfect option, whatever your sleeping style, preferences or budget.

If you're struggling with an ancient, worn-out mattress, you'll likely find that the process of buying a new one has changed a lot over the years. While you can still head to a big out-of-town store to bounce up and down on a few options, the majority of mattress shopping now happens online (what a surprise). You can pick the mattress that suits you best, get it delivered as a bed-in-a-box and in most cases, try it out for at least 100 nights (sometimes up to a year) with the option to return it if it doesn't agree with you.

Our number one best mattress is the luxurious Simba Hybrid Pro, which combines springs and foams and delivers sumptuous comfort and impressive cooling properties. If you want to sack off springs altogether, check out the Emma Original; it's extremely comfortable and great value to boot. If neither one of those take your fancy, we have plenty of hybrid and other material options for you to explore, and if you're a memory foam fan, you can check out our best memory foam mattress guide.

As the mattress industry is fiercely competitive, big discounts are common (read: you can basically ignore that RRP), so make sure to check out Amazon for any deals on our best mattresses. The price widget with each entry on our list will automatically pull in the cheapest price for each model, but you can also consult our best cheap mattress deals page for a rundown of where to find the best bargains right now.

Firmness: medium

Top cover not removable

The Simba Hybrid Pro is one of Simba's high-end offerings, and delivers exceptional comfort. It's on the pricey side, but for our money it's the best premium mattress around – in fact, it has picked up the T3 Best Mattress Award for two years running, in 2021 and 2022.

The seven specially engineered layers include a dreamily soft top layer, a natural wool layer to help regulate temperature, and two layers of springs. The top layer of softness gives you something to sink into as you lay down, but just a little, before you hit the supportive layers underneath, which deliver a reassuring level of firmness. These firmer lower layers also make it easy enough to move around on, and the motion isolation and edge support is good too. Many memory foam mattresses can trap heat, but in our Simba Hybrid Pro review, our tester was very impressed with the temperature regulation on the Hybrid Pro. The only down-side of the design, really, is the lack of removable cover; a feature we'd usually expect at that kind of price point.

The Simba Hybrid Pro is rated 6.5 out of 10 on the firmness scale, which means it's at the softer end of medium. If you prefer something firmer, check out the Brook + Wilde Elite (number three in this list) in Firm, or the Eve Premium Hybrid instead (our Eve Premium Hybrid vs Simba Hybrid Pro breaks down the differences between those two). The Hybrid Pro sits at the pricier end of the market, but Simba mattress deals are a regular occurrence, so you shouldn't have to pay RRP. And if you like the sound of a Simba but can't afford this one, we also highly rate the cheaper, less advanced Simba Hybrid Original.

Reasons to avoid

Too soft for some preferences

The comfortable, versatile Emma Original sits right at the top of our best memory foam mattress ranking, earning a solid four stars in our Emma mattress review. The design of this medium-firm mattress is simple but effective. Three layers of different foams: Airgocell foam on top (to mould gently to your body), viscoelastic memory foam in the middle (for pressure relief and support), and a firm HRX foam foundation. The cover features a temperature-regulating top and a breathable non-slip bottom as well as handles for rotating (you don't have to flip it), and it's removable and machine-washable, too. The RRP of this mattress fluctuates, but regular Emma discount codes and deals mean it's typically amongst the most reasonable options around.

There are a couple of potential down-sides to be aware of. The first is that the Emma Original tends to trap heat a little, so if you sleep hot, you might be better going for a hybrid model, as the springs offer better airflow. Second, it's on the softer side. If you need more support, we'd recommend a firmer option like the Nectar memory foam mattress (number 8) or Otty Pure mattress (number 5).

Too firm for some

The first and only mattress from Panda London, the Panda Hybrid Bamboo mattress is an eco-friendly firm and comfortable offering, made of premium bamboo materials. Bamboo is sturdy yet silky soft, meaning it'll last for a very long time. Panda's very own bamboo infused foam acts like memory foam that moulds to the body, cradles it and aligns the spine while you sleep.

Where Panda London stands out from the rest is its eco-friendly and sustainable credentials. All organic bamboo in its products are sourced from approved forests, grown pesticide free and is vegan friendly. Panda reduces its environmental impact at every stage of the product’s lifecycle, and the foam in the mattress can be 100% recycled. See our 5-star Panda London Hybrid Bamboo mattress review for more details.

Reasons to avoid

Edge support could be better

The OTTY Pure mattress pushes the boat out with some pioneering materials. In place of regular memory foam you've got a foam made from bamboo and infused with charcoal; both materials chosen for their temperature regulating, anti-fungal and antibacterial and hypoallergenic properties. It's hard to gauge those things when sleeping on it, but thankfully it also shines when it comes to comfort. 

In our OTTY Pure review, our tester found this mattress superbly supportive, with decent temperature regulation and great build quality. OTTY says it's a 6.5 on the firmness scale but we think it feels firmer than that – perhaps a 7.5. The surface feels plush and soft when you press on it with your hand, but lying down there's great overall support, including underneath your hips. You'll also sink in very slightly, but this is a mattress you sleep 'on' rather than 'in'. The layer of generous 16cm springs are there more for support than bounce.

You do pay a premium for the bamboo and charcoal, so if this mattress is out of your price range, consider the OTTY Hybrid Original, which we were also impressed with. Or hold out for an OTTY discount code to take the price down. If you want the feel of more traditional memory foam, alternatives to explore would be the Emma Original or Eve Original.

Takes a week or so to 'break in'

The Premium is Emma's high-end offering, and it combines many of the features from the ultra comfy original, but builds on them for something that's generally more luxurious. The big structural difference is the addition of tall springs, which have the effect of making this model firmer than the Original, and also promoting airflow through the mattress so it sleeps cooler (if we're nit picking, it does still trap heat a little bit).

In our Emma Premium mattress review, our tester noted no sinking feeling to speak of (another key point of difference compared to the Original), but instead a firmly bouncy sleep surface. We found it took a little while to break in – around a week – but after that, it was both dreamily comfortable and ultra supportive. Delivery was smooth, and you've got that 200-night trial and 10 year guarantee for peace of mind. Like most entries in this best mattress guide, we'd suggest ignoring the (quite high) RRP, as there's almost always a good Emma mattress deal to take the price right down.

Too firm for some

A new and improved version of the Emma Premium, the Emma NextGen Premium has made some serious advancements when it comes to its heat control. The mattress has brilliant temperature control and heat regulation, which helps you keep cool and at a pleasant temperature throughout the night. Surprising, considering how soft, cosy and thick its cover feels.

Like most Emma mattresses, the Emma NextGen Premium has a firm level of support and comfort, which might be firm for some but will suit most people and their sleep positions. The hybrid mix of foam and springs moulds to the body but doesn't give that sinking feeling you find with some hybrid mattresses... oh and it's pretty affordable too!
