Best Mattresses Under £500: Comfortable Sleep Without Overspending

You don't need to spend a fortune to find a mattress that feels genuinely good to sleep on.

Under £500, there is a surprisingly wide choice. You can find pocket sprung mattresses, memory foam designs, hybrids and deeper comfort-focused models from familiar UK brands, with options for everything from a spare room to the main bedroom.

The trick is not simply to look for the cheapest mattress. It's to work out where your money is best spent — whether that's on springs, cushioning, cooling materials, depth, or simply a feel that suits the way you sleep.

What can you actually get for under £500?

Quite a lot, as it turns out.

The current Mattress365 range includes mattresses under £500 from brands including SleepSoul, Silentnight, Deepsleep, Gilt Edge, Kayflex, Postureflex, Baker & Wells and Uno. There are also plenty of choices between soft, medium-soft, medium, medium-firm and firm tensions.

That means the £500 mark isn't really a particular type of mattress. It's simply a useful point in the market where you can start comparing different constructions and decide where you want the money to go.

Some mattresses in this range are straightforward everyday models. Others bring in pocket springs, memory foam, gel, hybrid construction or deeper profiles that make them feel considerably more substantial.

Start with the feel, not the price

It's easy to approach a £500 budget by looking at the price first and the mattress second.

A better approach is to decide what you want the mattress to feel like.

Do you prefer a softer, more cushioned surface? Something medium and balanced? Or a firmer mattress that feels more responsive when you move?

Once you know that, the budget becomes much easier to work with.

Mattress365's Find the Right Mattress for You guide is a useful place to start if you're unsure which firmness or construction suits you.

Pocket springs: the classic choice

Pocket sprung mattresses remain one of the most popular choices because they offer a familiar combination of responsiveness and support.

Individual springs sit inside separate fabric pockets, allowing them to react more independently to movement and weight. They can also provide plenty of airflow through the mattress.

And you don't need a huge budget to get a substantial spring count. The current under-£500 range includes everything from simpler pocket sprung mattresses to models with 2,000 or even 3,000 pocket springs. 

If you like a mattress that feels responsive rather than deeply enveloping, pocket springs are a good place to look.

You can explore the Pocket Sprung Mattress Buying Guide for more detail.

Memory foam: a softer way to sleep

Memory foam has a completely different character.

Rather than pushing back immediately, the foam gradually moulds around the body. That can create a more cushioned, close-fitting sensation, particularly around the shoulders and hips.

There are several memory foam options under £500, including mattresses from Kayflex, Silentnight, Baker & Wells and other brands in the current range. :contentReference[oaicite:3]{index=3}

If you prefer less bounce and more of that gently cushioned feeling, memory foam can be an attractive choice without needing to move into the premium price brackets.

Hybrid mattresses: the middle ground

If you like the idea of springs but also want some of the cushioning associated with foam, a hybrid can be an interesting compromise.

Hybrids typically combine pocket springs with memory foam, gel or another comfort material. The result can feel more layered than a straightforward sprung mattress, while retaining some of the responsiveness and airflow of the spring core.

There are several hybrid options within the current £500 limit, including the SleepSoul Balance 800, Silentnight Studio Gel Hybrid, Kayflex I Zone Supreme 2000 Hybrid and Uno Sunrise Fresh Memory 1000 Hybrid. 

You can read more about how the different layers work in our Hybrid Mattress Buying Guide.

Six mattresses worth looking at

Rather than calling one mattress the “best” for everyone, these six show the range available at different points of the budget.

What should you prioritise with a £500 budget?

There isn't one specification that automatically makes a mattress better value.

Instead, think about the parts that will actually affect your night.

Your sleeping position

Side sleepers often prefer a little more cushioning around the shoulders and hips, while back and front sleepers may prefer a more responsive or firmer surface.

That doesn't mean there is a single firmness that works for every side or front sleeper. Body weight and personal preference can make a significant difference.

Our Side Sleeper Mattress Buying Guide, Back Sleeper Mattress Buying Guide and Front Sleeper Mattress Buying Guide can help you explore the differences.

How warm you sleep

If you tend to get warm during the night, pay attention to the construction rather than simply looking for the word “cooling”.

Pocket springs naturally leave space for airflow, while hybrids can combine spring ventilation with breathable comfort layers and cooling materials.

Our Cooling Mattress Buying Guide looks more closely at the materials and features that can influence how a mattress feels at night.

The size of the mattress

Remember that a “£500 mattress” can mean very different things depending on size. A model listed from £300 may be comfortably under budget in a Single but cost considerably more in a larger size.

Always check the price for the exact size you need before making your final choice.

Is £500 enough for a main bedroom mattress?

Yes — depending on your expectations and the size you're buying.

The current Mattress365 range shows just how much variety exists below this point. There are medium hybrids, deeper pocket sprung mattresses, memory foam designs and established-brand models all competing within the same broad budget. :contentReference[oaicite:11]{index=11}

The key is to avoid assuming that spending the full £500 is automatically better than spending £300.

If a £300 mattress has the construction and firmness you prefer, there may be little reason to spend another £200 simply because the budget allows it.

A few things worth checking before you buy

Once you've narrowed down your choices, there are a few practical details worth checking.

Look at the mattress depth and make sure it will work with your existing bed and sheets. Check whether it is turnable or non-turn, and take note of any warranty or guarantee included with the model.

If you're buying for two people, consider motion transfer and the amount of usable sleeping space. If you're replacing an old mattress, make sure your bed base is still in good condition too.

And if the mattress is being delivered rolled, remember to follow the manufacturer's instructions carefully when unpacking and allowing it to settle.

Our Mattress Care Guide has more practical advice for looking after your mattress once it arrives.

The final thought

£500 is a useful mattress budget because it gives you room to explore rather than forcing you into one particular construction.

You can choose a straightforward pocket sprung mattress, explore memory foam, move towards a hybrid or spend more of the budget on a deeper spring system.

The right choice will ultimately come down to the feel you prefer, the way you sleep and the size you're buying.

And perhaps the nicest thing about shopping at this price point is that you don't have to make the decision feel complicated. Start with how you want your mattress to feel, then find the construction that gets you there.
