Best Firm Mattress UK – A 2018 Expert Buyers Guide

Best-Firm-Mattress-UKSo you’re after the Best Firm Mattress?

Well you’re in the right place!

I’ve rounded up and reviewed the 5 best firm mattresses available. Whether you’re looking to sort out a bad back or you just can’t sleep on the soft bed you’ve got now we’ve got you covered.

But before we dive into finding the best firm mattress let’s take a look a some of the different things you have to consider.

Best Firm Mattress Material

Getting the right material in your mattress is a great place to start, it’s the foundation of the mattress and the base of your sleep. But there are a few different types to choose from and it can get a bit confusing so let’s take a look at the differences between the materials.

Memory Foam

Normally I’m a huge fan of memory foam, it’s super comfortable and offers great back support. But the problem is, memory foam isn’t firm! It’s naturally designed to soften and mould around you so will never give you the truly firm feel you’ve been looking for.

The only time you might find memory foam in a firm mattress is if it’s in a hybrid mattress. This is a combination of both memory foam and springs, so if a small layer of memory foam is layered on top it can add some back support while staying firm.Similar to putting a memory foam mattress topper on top.


Now spring mattresses are much better suited for what we need. But within the world of spring mattresses, we have two types.

Pocket Sprung

Pocket sprung mattresses are the most comfortable, each spring is sewn into its own pocket so they can move independent of each other, that way it sinks where it needs to giving you maximum support and a superbly comfortable bed.

The main difference between one pocket sprung mattress and another is the spring count. That’s how many springs are in a king size of the mattress. More springs is generally better because it means your weight is more evenly distributed and the bed can form to your shape better. The ideal number of springs is usually from 1000-2000, Less than that and you’ll be uncomfortable while more won’t cause a problem, it’s just a lot more money for how much comfier the bed will actually feel.

Open-Coil Springs

Open-coil springs are a big grid of springs, they aren’t as comfortable as their pocket spring counterparts but they have the advantage of being much cheaper. So a great budget alternative but be aware it’s not luxury comfort. Just because the mattress is firm doesn’t mean it can’t be comfortable!

Of the two, pocket sprung is definitely the way to go.


Last but not least, you have latex mattresses! Latex mattresses have a similar feel to memory foam but they have a lot more bounce in them. This resistance gives them a great firm feel.

Latex is an excellent choice if you’re looking for a firm mattress to help with back problems.

So for most people the best material will either be latex or pocket sprung.

Always Check Any Guarantees

A good mattress will last you 10-years before it needs to be replaced so ideally, you want to get a mattress with a guarantee as close to that as possible. Because a mattress is an investment in yourself and your sleep, so you want a good one that’s going to last.

Latex is an excellent choice of filling for a mattress. It contours to the body giving you great support and comfort while still being firm to lie on.

It is a premium product but well worth the price, the knitted cover is breathable keeping you cool at night while latex is naturally hypoallergenic so your kept dust mite and allergen free every night.

The latex is then split into seven zones of varying firmness giving you more support in your shoulders and hips then less in your head and feet for a balanced feel across your whole body.

Venice Ortho Mattress

The Rest Assured mattress is another great budget mattress, but this time with pocket springs for added luxury comfort.

It has a spring count of 1400 which is very respectable and more than enough for a comfy night’s sleep. The only problem is it’s only 23 cm deep so (in the nicest way possible) if you are especially heavy then this mattress might not be right for you.

But if you aren’t then you can get yourself a superbly comfortable firm mattress at a great price! The mattress has also been treated to make it hypoallergenic which is great because generally, it’s just memory foam and latex mattresses that have that great quality.

Overall, a superb budget model that provides firm comfort every night and a nice guarantee so you can be sure you get your money’s worth.

    Hi DozyOwl

    Would like your feedback between the 1500 spring hybrid vs the ultimate backcare in terms of firmness.

    I’m looking for a mattress that is very firm and the above two falls within my budget. I would assume the ultimate backcare is the better option as it has more pocket springs?
    Many Thanks

      Hi Vincent,

      Great question! Glad you’ve got a couple you like. Yes you’re right the Ultimate backcare is the better option, more springs and it’s slightly thinner so it’ll be the more comfortable and firmer of the two.
