Comfort is obviously a difficult factor to review, this is where buying online obviously makes things a little more difficult, but follow these key considerations and you’ll be confident that you’re buying the perfect Mattresses for your personal preference.

– Hardness – different people have very varying preferences when it comes to the level of hardness they like from their mattress. Some love the ultra soft feeling of sinking into a soft mattress. Whereas others prefer the support provided by a very firm mattress. Of course there’s a whole spectrum of varying comfort levels in between the two. The first port of call here is to check the hardness level of your current mattress and use that as a basis for your new purchase. I.e if you’re perfectly happy with the current level of hardness then try and look in the same region, of of course if it’s too hard look for a softer level of mattress.
– Springs – this is where you’ll start getting lots of technical sales jargon as there are so many different types of spring available for mattresses. For example some have traditional coil springs, some have pocket springs and then there’s a tendency for some of the more high-end mattresses to increase the number of pocket springs in the mattress, with the theory that the comfort will increase. Take your time to read about the particular features and the benefits of each type to determine which type best suits your needs.
– Material (memory foam?) – of course there’s also the material that you need to consider, with a great deal of options to choose from. Memory foam is one of the more popular materials on mattresses nowadays because of it’s ability to shape around your body, therefore not putting undue pressure on parts of the body like hips and shoulders. Some mattresses offer a blend between the traditional spring mattress and the memory foam mattresses by offering a memory foam topper to a standard or pocket spring mattress.


A typical mattress should last you somewhere in the region of 8-10 years, so whilst the cost seems like a huge expense now, do bear in mind that it’s going to be used every night for those many years, so even a top end £1000 mattress only works out 27p a night over 10 years.


If you’re keeping your existing bed then this is an easy part of the decision making, as you’ll need to choose a mattress size that matches your existing one. However if you are buying a new bed at the same time then there’s a careful decision to be made on what size you go for. Consider the size of the room and also your needs.

Typical mattress sizes are:

Mattress Size (W x L)
Super king 6’0 x 6’6
180 x 200
King 5’0 x 6’6
150 x 200
Double 4’6 x 6’3
135 x 190
Small double (Queen) 4’0 x 6’3
120 x 190
Single 3’0 x 6’3
90 x 190
Euro single 3’0 x 6’6
90 x 200
Small single 2’6 x 6’3
75 x 190
Toddler 2’3 x 4’6
70 x 140

Other tips

Other advice that we have, is to spend a bit of time trying different mattresses in local retailers, a bit cheeky if you’re then going to buy online, but it’s a really great method of getting to try different brands, materials and levels of hardness.
