Best Memory Foam Mattress Under £500
SleepSoul Space 2000 Pocket Memory Pillow Top Mattress
If you love that soft, body-hugging feel of memory foam but don’t want to spend a fortune, the SleepSoul Space 2000 is a great pick. It’s not just a plain foam mattress, it’s got memory foam for pressure relief, plus springs underneath to give it some bounce and help keep things cool.
The memory foam layer moulds to your shape, which is great if you wake up with sore shoulders or hips. And unlike some foam mattresses, this one won’t make you feel like you’re sinking into quicksand.
Why it’s great:
- Cushiony comfort – Memory foam gently supports your body where you need it most
- No sweaty nights – The springs underneath help with airflow so you don’t overheat
- Soft on top, supportive underneath – You get the best of both worlds
- Still under £500 – Even for king size or superking
If you want that memory foam comfort without feeling too warm or stuck, this is a solid, budget-friendly option.
Best Firm Mattress Under £500
Sealy Mellbreak Ortho Plus Mattress
If you need a mattress that’s properly firm and keeps your back in line, the Sealy Mellbreak Ortho Plus is a solid choice. It’s built for people who want strong support without the fluff. The springs are specially designed to keep your spine aligned, and there’s extra support in the middle where most of your weight goes.
It’s ideal for back and stomach sleepers, or anyone who wakes up with aches and needs a mattress that doesn’t give way.
Pros:
- Really firm and supportive
- Good edge support
- Extra support through the middle
- It’s double-sided, which can help it last longer
- Comes with a 5-year warranty
Potential cons:
- If you sleep on your side or like a soft, cushiony feel, this might be too hard
- You’ll need to flip it
- A bit deep (28cm) – double-check if your fitted sheets will fit
- Some people have reported early sagging – Though that’s covered under warranty
How to Choose a Mattress Under £500
Compared to a £300 limit, there’s a lot of choice with a £500 budget. But that can make it harder to decide.
Here’s what to look for:
- Stick with known brands
- Pocket sprung mattresses are still king for all-round support
- Memory foam is great if you like a soft, cushy feel
- Check reviews, especially long-term ones
- Test in-store if you can (Bensons, Dreams, IKEA)
Is it worth spending more than 500?
If you can afford it, spending more usually gets you better materials, more springs, or deeper comfort layers. But £500 is a solid budget for a reliable mattress that should last 7-10 years.
Tips:
- Don’t fall for inflated RRPs
- Focus on build quality and reviews
