Five reasons to buy a mattress online

If this is your first time browsing mattresses online, you may be feeling a little intimated or overwhelmed.

What is a bed-in-a-box mattress?

How can a full-size mattress be stuffed into a box?

And can these mattresses be any good?

A bed-in-a-box mattress is a high-quality mattress that's rolled up, vacuum-packed and sealed in a compact box that's shipped straight to your front door. Unpack it, and it'll expand to its full size - without affecting the quality!

They're usually medium-firm mattresses suitable for side sleepers, back sleepers, and stomach sleepers of any age, weight, or build.

And most of them come with removable and washable covers to make them hypoallergenic.

But how could you possibly decide on a mattress if you haven't seen it, felt it, or laid on it?

These are typical concerns for first-time online mattress buyers.

That's why we'll start by sharing five simple reasons why we think buying a mattress online makes more sense.

1. It's so much easier

You can browse, choose, and order your new mattress from the comfort of your own home - in your pyjamas if you wish!

Once ordered and paid for, the mattress will be rolled up, vacuum-packed, and delivered straight to your front door - free of charge - within a few days.

All you need to do is unpack the mattress, break the vacuum seal, and it will return to its original size within a short period.

But what if you don't like the mattress you've ordered?

Of course, we try to help you make the best decision before you buy by giving you in-depth mattress reviews, but the only real way to see if a mattress is perfect for you is by trying it for a minimum of three weeks.

But there's no need to worry.

Most mattresses ordered online come with a risk-free trial period.

If you're not satisfied with your purchase, you can contact customer services and return the mattress for a full refund.

The convenience of buying online saves you time and effort.

2. Better selection

Buying online does not mean that you're compromising on quality.

New production techniques and a focus on the easily-compressed, usually Certipur-certified and more breathable, memory foam make it possible to produce high-quality mattresses that can easily be rolled up and vacuum-packed without damage.

But you'll also find other types of mattresses online, like hybrid mattresses that combine the best characteristics and airflow of spring mattresses with the pressure relief capabilities of a top layer of memory foam in one compact foam bed.

You can order any of these mattresses at the mere touch of a button.

In fact, several best-selling mattresses only sell online.

This means that you can enjoy a greater selection of mattresses online than you can at your local retailer.

And these are all available in your favourite standard UK mattress sizes, ranging from the single, double, small double, king-size, super king, and even emperor beds!

3. Risk-free delivery and free returns

There is no denying how remarkable the risk-free trial periods of online mattresses are.

It's hard to see if a mattress is perfect for you by lying on it for a few minutes in a store, under the scrutinising eye of salespeople and other customers.

But if you order a mattress online, you can test it out for a couple of weeks in the comfort of your own home.

You'll know for certain if a mattress is perfect for you if you've tested it out for a few weeks.

And what's even better is that this luxury comes at no financial risk.

If you're not completely satisfied with your mattress, you can return it - free of charge - and get a full refund.

Most online mattresses also come with fantastic warranty conditions to keep you protected even longer.

4. Better value for money

Choosing a high-quality mattress is vital.

After all, you spend a good third of your life sleeping. This means that your mattress has to offer you comfort, stability, and support to keep you happy and healthy.

A good mattress doesn't come cheap, but you can get high-quality mattresses at better prices by purchasing online.

Typically, mattresses' price-performance ratio is up to 20% better online than it is in brick-and-mortar stores.


There are no middlemen, commissions, or rents that need to be covered.

You can also benefit from discounts and coupon codes that make buying your mattress online even cheaper.

Apply your coupon code upon checkout, and voila, extra savings in the bag!

5. Innovative products

No, online mattresses are not only available via Amazon.

There is a whole new generation of mattress brands available.

They combine modern technological industry knowledge with entrepreneurial spirit and design.

The result?

Innovative mattresses with stylish designs and new and exciting features that enhance the quality and comfort of your sleep.

And what's more is that they also focus on a range of other sleep accessories, like slats and box spring bed frames, mattress protectors, mattress toppers, duvets, and pillows to kit out your whole bedroom.
