How to choose the best Boxing Day mattress deal

We're all ready to jump on the Boxing Day bandwagon - but before you do, take some time to consider the purchase you'll be making. 🚂

Make sure you pay attention to the following when purchasing a mattress - or any other sleep accessory:

Pay attention to quality

The quality of your mattress directly affects the quality of your sleep - and none of us want to wake up cranky after an uncomfortable night.

Even if you're shopping on a budget, quality should always be the first point of consideration.

Luckily, it's perfectly possible to invest in a high-quality mattress at a good price, and all our top recommendations offer great value for money.

Find the right degree of firmness

Mattresses come in different degrees of firmness, and while there is no right firmness level, there is one that will be perfect for you. ☁️🧸🧱

Firmness is largely a matter of personal preference, but it can also be influenced by factors such as body size, age, and preferred sleeping position.

  • Lighter-weight sleepers and side sleepers generally do better on softer mattresses.
  • Heavier-weight and pure back or stomach sleepers generally do better on firmer mattresses.

It's also worth paying attention to the materials used in a mattress since this affects firmness significantly.

Consider the materials used

There are dozens of different mattress materials, but some of the most common ones include:

  • Pocket springs: Pocket-sprung mattresses are generally firm, supportive, cool, and durable.
  • Memory foam: Memory foam mattresses are generally soft, warm, and with good pressure relief and orthopaedic support.
  • Latex: Latex mattresses are eco-friendly and more natural, though often quite expensive.
  • Hybrid: Hybrid mattresses usually combine foam with springs, resulting in a best-of-both-worlds product.
  • Cotton, coir, or wool: Organic mattresses are usually made from more unusual natural materials.

As with the right degree of firmness, there is no right or wrong material to choose.

It's just important to match your preferences with the features of each material to select the right one.

Get the right mattress size

This may seem obvious, but getting a mattress that fits your bed base is important.

Standard UK mattress sizes include the small single, single mattress, small double mattress, double mattress, king size mattress, and the super-king mattress.

Your mattress size will also affect the size of your bedding and other accessories like mattress toppers, mattress protectors, and more.

Luckily, you'll find great Boxing Day deals on accessories, including mattress topper Boxing Day sales.

And if you're looking for a new bed, you'll likely find a good bed Boxing Day sale, too! 🏷️

Don't forget that some beds, especially more traditional-style bed frames, those with headboards, ottoman beds, or the popular TV beds, may be significantly larger than your actual mattress.
Storage beds like divan beds, however, will largely be flush with your mattress.
If you're short on space, you may even want to consider something space-savvy, like a high-quality sofa bed.

Choose risk-free trial periods

Most mattresses purchased online come with a risk-free trial period, free delivery (including next-day delivery date options), and free returns.

This is great news, as it allows you to try your new mattress in your home for a set period.

If you're unsatisfied with your purchase, you can return it for a full refund! 🙌

We'd always recommend going for a mattress brand that offers a good trial - a 30-night trial should be the absolute minimum since it usually takes at least 3 weeks to get used to a new mattress.

Check the warranty period

Most quality mattresses come with a minimum 5-year guarantee, but many of the best-selling mattresses we recommend have a 10-year guarantee - or longer.

Typically, a good mattress should last around 7 - 10 years.

Longer warranty periods are a good indication that you'll be getting one of the best mattresses in the UK.

Should you buy a mattress on Boxing Day?

Buying your next sleep investment at a discounted price is always a good idea, but remember to do your research and always opt for brands that offer risk-free trial periods on major purchases.

Frequently asked questions

  • When is Boxing Day?

    The next Boxing Day falls on Friday, 26 December 2025.

  • What is Boxing Day?

    Boxing Day is a holiday celebrated the day after Christmas Day, on 26 December.

    Unlike Black Friday and Cyber Monday, which stem from the United States, Boxing Day originated in the UK. 🇬🇧

    It is commonly celebrated in the United Kingdom and other Commonwealth countries.

    While Boxing Day always falls on the 26th, the bank holiday associated with it may take place on that day or one or two days later.

  • Why is it called Boxing Day?

    There are various theories as to the etymology [1] of the name.

    The most common one, however, links Boxing Day to an old tradition where servants of the wealthy were allowed to visit their families on the day after Christmas and received a box of gifts from their employer. 

    They would have to celebrate on the day after Christmas as they'd have to serve their employers on Christmas Day. 

    Contrary to popular belief, the name has nothing to do with the sport of boxing.

  • How long do Boxing Day sales last?

    Traditionally, Boxing Day sales only last for 24 hours.

    In more recent years, however, this has changed quite a bit and many Boxing Day sales actually extend beyond the actual day.

    You'll now find Boxing Day sales that last through the whole of December, sales that start on Christmas, and sales that run from Boxing Day until New Year's Day.

  • Why is Boxing Day a big sales period?

    Traditionally, Boxing Day was the earliest day after Christmas where people could return unwanted gifts, request exchanges or refunds, or redeem gift cards.

    Over time, this has led to Boxing Day becoming a popular shopping day.

    Common Boxing Day sales in the sleep world include mattress Boxing Day sales, Boxing Day bed sales, and even mattress topper Boxing Day sales.

    It's the perfect time of year to refresh your bedroom for the new year, spice up your children's bedroom, or indulge in something luxurious at great prices.

    And it's the perfect way to keep the Christmas celebrations going. 🎄
