The Best Budget Mattress For Under £300

A good night's sleep shouldn't have to cost the Earth.

A mattress is an investment. Not only does it guarantee you a great night’s sleep, but it can play an important part in your wellbeing and overall health. So, paying for a good quality mattress that will last you years and deliver all the support and comfort you need is a worthwhile expense. But, you can get all that with a budget mattress.

You would be surprised just how much you can get with only a limited budget, and you can get a great quality mattress for under £300.

If the average mattress has a lifespan of eight years, (according to most manufacturers), spending £300 works out to just 10p a night for 2,920 nights worth of restful sleep. When you break down the cost, that’s not a lot for around seven hours of great sleep!

What is the best type of budget mattress to buy?

There’s a huge variety of budget mattresses on offer, from traditional pocket sprung mattresses to the latest memory foam options. As with any other mattress, it’s important to find one that suits you and provides you with the right level of support and firmness. For more information, check out our guide on How to Choose the Right Mattress.

The more you spend, the greater the features, but even a budget mattress has plenty to offer. For under £300, you can even find mattresses with a Cool Gel layer to keep you cooler and fresher – ideal if you suffer from night sweats or are a ‘hot’ sleeper.

Are cheaper mattresses any good?

For many years, cheap mattresses were regarded as sub-standard. However, today, they are just as good as more expensive options, providing you with all the comfort and support you need. From pillow top mattresses through to orthopaedic, extra-firm choices.

The range of cheaper mattresses on offer today is far superior, providing everyone with the chance to sleep in absolute comfort.

The price will, of course, depend on the size of the mattress. So, if you’re buying a standard double mattress, you’ll find that the same type or make will be cheaper than a Super King from the same range. Bear this in mind when looking for a cheaper mattress and double-check the size of the mattress you need before you buy. If you’re not sure how to choose the right size, check out our Mattress Size Guide for more advice.

Is it worth buying an expensive mattress?

With all the benefits of a budget mattress ticking most of the boxes for the majority of customers, is there any point in spending out more money and buying an expensive mattress? Well, as the price goes up, so does the quality of the materials used. And with pocketed sprung mattresses, the spring count goes up with the price.

More expensive mattresses will use natural materials such as silk, cashmere wool, alpaca wool and even bamboo to create the ultimate sleeping environment. Tuft & Springs mattresses, for example, are only a little over the £300 threshold, and include luxurious layers of cashmere and silk for a fraction of the price of even higher end mattresses.

Buying an expensive mattress is definitely a worthwhile investment if you have the money to spare. They’ll last for years, with many having up to 10-year manufacturer’s warranties. So even if the initial outlay is higher, that cost per night is still in the pennies rather than the pounds.

What is the best memory foam mattress under £300?

Starting with the most technologically advanced of our budget options. Memory foam mattresses offer unbeatable comfort and support. It has that all-important ‘spring back’ feature that effectively means you’re sleeping on a brand-new mattress every night.

Originally developed for NASA’s Space Program, memory foam is a dense foam that regains its original shape once pressure is removed. Read our Memory Foam Mattress Buying Guide for more information.

Most memory foam mattresses are ‘single sided’ mattresses, so you don’t need to flip and turn them regularly, making them easier to maintain. They also arrive boxed and rolled. A boxed and rolled memory foam mattress is easy to transport and takes just a few hours to expand into shape once it’s unpacked.

The Silentnight Memory 3 Zone Mattress combines both memory foam and the denser Reflex foam to provide a responsive medium firmness mattress with exceptional cushioned support. It sits right in our £300 budget range. And you’ll even have change left over to buy yourself the perfect pillows and duvet to match!

  • The medium firmness makes it ideal for back and side sleepers
  • The mattress reacts to your body temperature to soften and shape to the contours of the body, eliminating pressure points
  • It’s one of the thickest memory foam mattresses on the market at 18cm
  • A unique 3-zone sleeping system provides different degrees of support

This gives you a softer, more comfortable feeling without compromising that firmness you need.
It also provides you with:

  • 2000 individually pocketed springs that distribute weight evenly and stop any movement transference, no matter how much you move around at night
  • Easy maintenance, thanks to the single-sided design, so there’s no need to flip and turn
