        After being let down by another company

        After being let down by another company (my mattress getting lost in transit). I was dubious about getting another mattress ordered however my delivery was on time and delivery updates were accurate. The two delivery chaps were efficient and polite and the old mattress taken away. Very pleased with the service and product.

        Great service

        Other suppliers were quoting long lead times. Ordered and the mattress we wanted was delivered the next at the specified time and our old one taken away. Very pleased.

        Sleepsoul Space, 2000 double mattress My daughter had purchased this mattress

        My daughter had purchased this mattress so I didn't have to do much research, I was able to check her mattress in the first instance. The mattress itself has a 10 year warranty and is which recommended. It was in the sale at the time and with a little research through money back options and my blue light card I had a little extra discount so this made it value for money also. The mattress is excellent quality and I feel very supported. I am able to sleep on my front without pain now which is great. There are two things I would like to make others aware of which I overlooked. Firstly, there is an extra charge for the mattress to be taken upstairs. I didn't notice this, initially I wasn't bothered as in my younger days I worked in a hotel and moving mattresses was standard - please pay to have your mattress taken upstairs. The mattress is 45kg and I couldn't move it by myself at all. The second thing. The mattress is very well wrapped, twice. The inner wrapping is thick plastic and vacuum packed, the outer wrapping is like a extra strong cling film. I have seen the comedy sketches where mattresses open and surprise people. I assumed it would be the inner layer which would spring the mattress open. It isn't! the outer cling film layer once you release it opens the mattress fully. I live alone, and it opened quickly and upside down, turning this over was a challenge so please be careful. The mattress is deep and feels luxurious. I had to order all new mattress protectors and sheets which is a lovely extra treat. My bed is now super high too. Great for me - I feel like a queen. But it makes it hard for my dog who now struggles to get on the bed ( and shes a big dog!), something else to bear in mind. I definitely recommend this mattress.

      What is a medium firm mattress?

      A happy middle ground between medium mattresses and firm mattresses, our medium firm bed mattresses offer plentiful support without making any compromise on comfort. The design emphasises cushioning while still providing firmness, suitable for slightly heavier individuals and those who favour a firmer bed.

      The density of memory foam mattresses is measured in pounds per cubic square foot or PCF. A medium-firm memory foam mattress will have a PCF of around 5-5.4 PCF. High density foams contour the body well, which is why memory foam mattresses are good mattresses for side sleepers. You’ll find that many medium-firm memory foam mattresses are ‘hybrid’ designs with a sprung core. This provides you with extra support and firmness. For more information, you can read our Memory Foam Thickness and Density Guide.

      What does a medium firm mattress feel like?

      Those who appreciate plushness and a cushioned feel may lean towards medium firm memory foam mattresses, while medium firm pocket sprung mattresses are better for those who don’t want to sink deeply into their mattress.

      For those with more specific needs, it’s best to check out latex mattresses, pillow top mattresses, and specialist orthopaedic mattresses.

      What types of medium firm mattress are there?

      There is a variety of medium firm mattresses on offer. Choosing the right one will depend on your preferences, how you sleep, and your size. 

      Memory foam mattresses

      These are ideal for back sleepers, as the memory foam comfort layer moulds to the shape of your body, providing support at all the key spots. They do retain the heat so if you suffer from hot flushes look for a mattress with a ‘CoolGel’ layer.

      Pocket Springs

      With individually pocketed springs forming the core, these mattresses minimise movement transference for a more restful night’s sleep. They also allow the air to circulate so create a cooler sleeping environment.

      Traditional open springs 

      These mattresses use an open spring matrix with high-tensile steel springs that provide support. They’re a great budget option but do need to be maintained by regularly flipping and turning.  

      Hybrid mattresses 

      These combine top layers of memory foam with a sprung core for additional support. Hybrid mattresses are a great choice for all-round comfort and for any budget. 

      Is a medium firm mattress good for back pain?

      Chronic aches and pains in the joints and in the back can hinder quality of sleep, potentially leading to further health problems down the line. Finding the right mattress for back pain can help alleviate these woes, promoting correct spinal alignment, and moulding the individual's sleeping position to combat the pain.

      Our medium firm mattresses for back pain are adept at soothing ailments and providing high levels of support without adding pressure to the back. For additional cushioning, our medium firm memory foam mattresses provide the response needed for pressure points in the body.

      Similarly, our medium firm orthopaedic mattresses focus on posture, soothing back and joint pain to aid with a peaceful night’s sleep.

      Is a medium firm mattress good for side sleepers?

      People who sleep on their side place huge amounts of pressure of their hips and shoulders, particularly if they’re restless in the night. As such, a medium firm mattress is the peak of the firmness scale for side sleepers. Most popular are types which offer additional elasticity, such as latex or memory foam.

      Pillows are also incredibly important for side sleepers, as the position places extra pressure on the neck. Our pillow range has a real range of depth. Expect everything from anti-snore to anti-allergy, allowing you to drift off peacefully and pain-free.

      Which is best, firm, or medium firm mattress?

      Finding the right tension levels for your sleeping needs is a crucial element to consider when searching for the perfect sleeping environment. The difference between firm mattresses and medium firm mattresses boils down to the additional cushion provided by the latter. A firm mattress is perfect for the heavier sleeper, supporting extra weight without providing undue pressure to joints.

      A slight step down the firmness scale, a medium firm mattress is the mattress of choice for those who desire a firm yet slightly soft mattress. Consider any specific requirements you have and choose the best mattress from our range to improve your quality of sleep.

      How to choose the best medium firm mattress

      The sheer range of sizes on offer in our medium firm mattress collection make them suitable for all ages, although firmness level is often geared towards helping with back pain. Lighter individuals may wish to move down to the softer end of the firmness scale.

      If you’re looking for the best mattress for back pain, a medium firm choice is often ideal. They offer the right level of support without compromising on comfort. If you want a memory foam mattress without the sprung core, look for a thicker mattress as this will give you a firmer feel.

      Our comprehensive range of value and luxury mattresses with medium to firm firmness levels come in a host of sizes. Expect everything from a medium firm single mattress all the way to the luxury and magnificence of medium firm super kings. We also offer medium firmness mattresses in every style imaginable to suit any night time requirement – think memory foam, pocket spring, natural, and plenty more.

      Another advantage of medium firm memory foam mattresses is that they often come boxed and rolled, making them easy to transport. No trying to squeeze a full-size mattress around that tricky staircase! Simply unbox, unroll, and allow the mattress around 24-48 hours to ‘relax’ into its final position. If you take advantage of our free mattress delivery service, you can also arrange for your old mattress to be collected by our teams and disposed of ethically.
