Best Soft Mattress UK – A 2018 Expert Buyer’s Guide


Looking to lie on a cloud of softness while your drift off to sleep?

Look no further!

I’ve found the best soft mattresses and given a short review of each. And I’ve linked through to where you can buy them so you can check out the price and see some more information.

But first, let’s take a look at what you need to know before you buy.

Soft Mattress Materials

There are a couple of different materials you want if you’re looking for a soft mattress, memory foam or pocket spring.

Memory Foam

Foam and Memory Foam Mattresses are ideal soft mattress materials because foam can be made to be very soft! It’s also completely hypoallergenic and gives you extra support on your joints and back.

Memory foam moulds with your body heat so as your warm body lies on the mattress it heats up the foam which causes it soften and hugs to your body.

Not all memory foam mattresses are made the same and some will be firmer than others so you need to get the right one if you’re looking for a soft mattress.

Memory foam is a great material choice if softness is what you’re looking for.

Pocket Sprung

Pocket springs are individually wrapped springs that all get lined up inside the mattress. Far superior to open coil springs which are all fused together in a big grid, individual pocket springs can move independently of each other.

The softness comes from the spring tension so again not all pocket sprung mattresses are soft but the right one will give you a super soft bed to sleep on.

Pocket springs are a great choice if you still want a bit of bounce in your bed and want softness without a sinking feeling.

Hybrid Mattresses

Lastly we have hybrid mattresses which are a combination of memory foam and pocket sprung giving you the best of both worlds. Extra support from the memory foam and added familiarity of the pocket springs for extra bounce.

Be Aware Of Back Pain

Soft mattresses can be very comfortable to sleep on but they have one major drawback, and that’s a lack of back support.

It’s not so bad if you sleep on your side because there’s not as much pressure on your spine. But if you’re a back sleeper, you need to be aware that if you ever wake up with a sore back then it will likely get worse if you buy a soft mattress.

If you’re worried but still want to get a soft mattress then go for a memory foam option, memory foam provides extra support along your back and supports your joints where you need it most.

Price & Reviews

The Coolflex memory foam mattress is one of my favourites because of the bamboo cover. Bamboo is a wonderful material that is hypoallergenic and temperature controlled so it keeps you at just the right temperature all night long.

Coolflex combined a soft memory foam with their own reflex foam which helps give it extra support, ideal if you’re worried about a bad back developing.

Hybrid Signature Mattress

Material: Hybrid

  • 1500 Pocket Springs

Price & Reviews

Kayflex have a great hybrid mattress with 75mm of memory foam and a spring count of 1500. Generally the higher the spring count the more luxurious the feel with 1000 being low, 2000 being high and 3000 being luxury.

So 1500 is perfect level to give you a nice soft feel with plenty of comfort. It’s got a 25 cm depth so will sit fine on any bed and the hybrid combination gives it a really comfortable feel. Extra support from the memory foam keeps it soft but the springs give it a little bit of resistance when you lie on it for maximum comfort.

Again a 1-year guarantee isn’t ideal but it does have a 5-year warranty so it’ll definitely last.

Overall, a great mattress for those who aren’t ready for a full memory but still want a soft feel.
