How to choose a mattress
When choosing a new mattress it is important to think about how you sleep!
Find the right mattress that supports your sleeping style. Side sleepers typically require a softer mattress for added cushioning, while back and stomach sleepers benefit from a firmer one for proper support. When shopping for a child, choose something that supports their growing body.
Consider your budget. To ensure you’re getting the best price on your chosen new mattress, always shop around and compare prices to find the best deal. or hold out for the regular sales or special promotions that take place throughout the year. You can also open the live chat box and speak with a company representative to discuss the specifics of the available deals.
Decide on the type of mattress you want. From pocket sprung or memory foam to hybrid or orthopaedic, there are a plethora of mattress designs to choose from. Each has its pros and cons, so it’s essential to conduct thorough research before making a decision.
While a mattress can be pricey, it’s an investment that’ll give you years of restful sleep – totally worth it!

Where to buy mattresses in the UK?
Many online retailers now offer mattresses in a box, providing shoppers with a wider choice, varied price points, and ease of installation.
For shoppers that prefer trying before they buy, you can buy a mattress at a range of furniture and homeware shops, but you’ll get the best deals at specialised mattress retailers, including:
How to spot a good deal on a mattress?
When researching mattresses, you’ll quickly discover there are always deals to be had – no matter what type of mattress you’re looking for.
Brands like Simba and Emma often run regular offers, and stores like Dreams and Bensons for Beds hold sales with discounts on select mattresses.
If you know you need a new mattress soon, January sales can be a great time to buy, with generous stock clearances and significant discounts.
However, if you can’t wait for sale events, then make sure to shop around and compare prices before parting with your money.
You may also want to consider upgrading your bedding or adding a mattress topper while you’re at it.
What is the best month to buy a mattress?
While it’s true that mattress retailers tend to drop prices on certain days, such as bank holidays and during big shopping events, you’ll find a great mattress deal in pretty much any month of the year.
According to The Sleep Foundation, many mattress brands introduce new models in mid-to-late spring.
This means that the prices on older models are often slashed dramatically, so spring could be the most sensible time to buy a mattress.
Should I wait until Black Friday to buy a mattress?
Mattresses need to be replaced every six to eight years: if yours is on the way out, you’ll probably find yourself desperate to buy a new one as soon as possible.
Black Friday takes place in November, so there’s not much time left.
Although it’s one of the best times to buy a mattress for less, there are risks involved with waiting until the shopping holiday.
As many people buy mattresses on Black Friday, those with the biggest discounts tend to sell out quickly.
You can generally find a good deal at any time of the year, so it might be best to shop the sale now while your favourite model is still in stock.
How much do mattresses cost?
A good spring mattress doesn’t have to cost much more than £150 for a double.
Memory foam mattresses tend to be a little more expensive, but you can find good quality doubles from £300.
Hybrid mattresses, which contain a mix of foam and springs, are more expensive still and can cost anything from £400 to £1,000 and above for a double.
Other factors to consider when purchasing include the length of the trial period you’ll receive (most internet-only brands offer 100 nights), as well as shipping costs, which can quickly increase your overall costs.
Some of the online-only brands, such as Emma, offer free delivery.
Which is the best bed in a box company?
Opinions on this are constantly evolving as newer and more innovative designs emerge on the market.
Most of the top bed-in-a-box brands have thousands of five-star reviews, so you can trust that there are plenty of quality options out there.
However, a few names consistently pop up in the best mattress lists.
Brands like Emma and Simba are recognised not only for their top-rated mattresses but also for their excellent customer service and delivery.
You can’t go wrong with any of these!
How often should you change your mattress?
The Better Sleep Council recommends replacing your mattress every seven years, but this is just a guideline.
If your mattress is in good shape and still comfy, you can keep it longer.
However, if you’re sleeping better in hotel beds or waking up sore, it’s probably time for a new one.
The best sleep routine and environment
Thomas Høegh Reisenhus, TEMPUR® sleep specialist & sleep counsellor, reveals the key components of a good bedtime routine and environment...
A sure-fire way to facilitate a better night’s sleep is to practice good sleep hygiene.
Establish a sleep routine that works for you and stick to it.
This will help your body establish a consistent, natural sleep-wake cycle which can do wonders for your overall sleep quality.
As such, try to avoid making up for lost sleep with a lie-in.
Instead of sleeping in, spend your morning reading a book in bed or having a leisurely coffee in the kitchen.
Ensure that your bedroom, bedding, and sleepwear are fit for purpose too.
The ideal sleep environment is dark, quiet, and cool – much like a cave.
If you find unwelcome sources of light are keeping you up, consider investing in an eye mask or black-out curtains.
Adding soft furnishings can be a great way to reduce noise, with the surfaces having an absorptive quality, but if this doesn’t work, consider embracing a soothing soundtrack to block it out.
In terms of temperature, try to keep your bedroom at 18°C. You can further reduce the risk of waking up due to overheating by ensuring that all your bedding and sleepwear is made with natural, breathable materials such as cotton and linen.
Bear in mind that everyone is different; what might work for most, may not work for you!
Whilst knowing how much sleep you should get, how to overcome common barriers, and practicing good sleep hygiene can facilitate a great night’s sleep, if you continue to struggle with sleep or fatigue persistently, do not hesitate to visit a doctor or health professional for support.
