    Coolmax Deluxe King Size Memory Foam Mattress Coolmax
    £ 229.99

    Product Details

    The King Size Coolmax Deluxe Memory Foam Mattress is a mid-range foam mattress with a cooling mattress cover. It scores well on price, performance and longevity, making it a popular choice for younger couples and new homeowners.

    The top memory foam layer is 5cm deep, which is enough to experience the full benefits of memory foam - luxurious comfort, support and pressure-relief. This also makes the memory foam mattress suitable for front, back and side sleepers.

    The base foam layer is quite deep and supportive; however with the soft memory foam layer on top the Coolmax Deluxe Memory Foam Mattress has a medium firmness rating overall.

    This affordable memory foam mattress comes with a CoolMax mattress cover which is removable and washable at 40 degrees. Coolmax fabric technology wicks away excess heat and moisture, to prevent you from stirring.

    This king size memory foam mattress is delivered rolled so you can easily move it to your room of choice.

    Iv bought 3 singles and a double absolutely great comfort and value for money
    Excellent highly recommend
    Excellent mattress and easily as comfortable as more expensive alternatives
    I initially bought a 4" thick off-cut from the MFW ebay store to make a large bed for my dog after knee surgery. Unfortunately he won't share it! After my chiropractor advising memory foam, I then decided to check the website for a human version! It was unbelievably easy to decide thanks to the reviews, descriptions and cost effective choices. The mattress arrived rolled up, small and portable. At first it was the strangest experience going from a spring mattress to memory foam, but I will never go back. I now have all the support I need. I also bought two contour pillows as part of the offer. I still haven't got used to these but it's probably because I sleep on my front/back and usually use skinny pillows. I would recommend MFW and their products to anyone.
    I don't normally take the time to write reviews but felt I had to after receiving my Coolmax Memory Foam Mattress. I am absolutely over the moon! I was a little dubious about buying something on the internet that I couldn't test but after reading other reviews I took a chance and bought one. My boyfriend and I are amazed at how comfortable it is. Price, service and delivery were great and I have absolutely no regrets with my purchase. I too have been boring everyone with how good it is and am now struggling to get up in the morning because it's so comfortable. Thanks v much!
    Best iternet buy ever!
    Just wanted to let everyone know how great this company really is! After searching for a memory foam mattress I came across Memory Foam Warehouse, sceptical at first because the mattresses that we were looking at was
    Brilliant Service & Mattress
    we was looking for a new mattress after months of sleepless nights and aching in the morning we decided to bite the bullet and get a new one. we brought the coolmax 800 memory foam mattress and have never slept better !! the service the memory foam warehouse provided was excellent and since then our friends have ordered from them too.
    coolmax performance 800 memory foam mattress
    I bought the coolmax 800 memory foam mattress to replace my old mattress for my Electric Bed as i am Disabled, Since having the mattress i wake up with no aches or pains and get the best nights sleep i have ever had. I would definitely recommend this mattress to all of my friends and family and to anyone that has back problems.

    Coolmax 800 memory foam... Such a treat!
    I requested a specific day for delivery but my order was processed so quickly they initially offered to deliver it within one working day, which is great if you need a new mattress straight away. Going from a firm spring to a medium Memory foam mattress is peculiar to start with but after initial concerns I have got used to it. I have become increasingly frustrated over the last couple of years at being constantly tired and aching far more than an active girl of 30 should. I have started to make other changes to improve my energy levels but my new mattress was the starting point and has made a real difference. I realise that I don't ache as much as I used to and sleep more soundly, waking naturally & feeling refreshed. It's the best investment I've made all year and such a bargain price too. I've happily recommended the mattress & website to my friends, volunteering my new mattress for tests :) I only wish I'd taken advantage of the memory foam pillow offer as well!

    Finally a great nights sleep
    We purchased this mattress as we were moving and were having a different bed and mattress to the one we were previously using. The mattress we had previously was generic and came with the bed we had purchased at the time. That mattress lasted us less than 2 years before some of the springs were broken and needless to say it made sleeping so uncomfortable. After a difficult move I can honestly say that sleeping on our lovely new memory foam mattress was amazing. It is so comfortable and as it is a medium firmness it is not too soft which was something I had previously been concerned about when deciding to purchase a memory foam matress as I have never had one before. The service I received when purchasing the mattress was fantastic and I was called when our mattress was delivered to store (we opted to collect it on a Saturday as we were moving house) and it was packaged in a way which made it very easy to transport. AMAZING MATTRESS, AMAZING SERVICE & AMAZING VALUE FOR MONEY - What more could you want?!
    Finally a great nights sleep
    Fulfilled A Dream
    About 15 years ago I stayed in a hotel, was so impressed with the mattress I had to see what it was. Later discovered it was memory foam. Since then I have longed for one but they were so expensive. When I saw your prices I thought I take a chance. I ordered and kept my fingers crossed. I was not disappointed, delivery was next day. What a difference, no aching back in the morning, bad shoulder felt so much better, very little disturbance when my husband tossed and turned. Thank you so much for the quality, delivery and altogether a brilliant transaction, it really has fulfilled a dream

    My mattress was delivered the day after I bought it. I unrolled it and was overjoyed with my first nights sleep and have been since. My hips are not sore any more getting out of bed and I feel totally rested. I'm so happy I picked a memory foam mattress and I am even more overjoyed at the price. I thought I would have to spend a lot more money to feel this rested. Thanks you I have not slept this well in years. Great fast service. xx

    Cant rate this highly enough
    I was a bit apprehensive about buying a mattress without being able to test it first, I've always gone for firm mattresses as they have been better for my back and this is medium but I went for it after a couple of family members were raving about memory foam. It came quickly despite ordering it over the Christmas period and I wasn't disappointed, I have been sleeping like a log since the first night, its like a gentle hug every time I get into bed, its not as soft as I thought it might be it really does just gently mould into your body and feels really supportive all over my body. At the sale price its an absolute bargain and I'm telling everyone i meet about it, the only problem now is that it's so comfortable I don't want to get out of bed in the mornings!
    Great price, quality mattress
    ordered the mattress on Sunday afternoon and received it on Tuesday at 1.30pm. The Kingsize Coolmax Performance 800 Memory Foam Mattress is excellent quality and extremely comfortable. I had a query on the day of delivery and my call was answered promptly and politely. I have since discovered that a colleague bought the same type of mattress elsewhere and paid twice the price I did. No surprises or disappointment with the whole process.
    now i can sleep
    Now i can sleep with out any back pain. I would recommend all of those who are complaining back pain. it really help and gives good night sleep. Not only that i would suggest best customer service from team. I am very pleased with my king size order. I will use them again.
    OMG - we have found sleep paradise!!!
    Wow - thank you! Neither myself or my husband has slept so well since buying one of your memory foam mattress with coolmax cover. I must confess it takes a couple of nights to get used to it after a spring mattress but let's just say that bedtimes are getting earlier and earlier!! I used to get back and neck pain but this has now gone. My 10 year son thinks its fantastic and we have promised him one if he does well in his 11+ (I have never seen him work so hard!). A work colleague now has your details. Reading the reviews were invaluable when making the decision and showed the Company had faith in its products and service by publishing the reviews. Ordering was easy and delivery as promised.
    Excellent Service
    Fantastic Memory foam matress. worth the money. I got the coolmax memory foam 800 and 2 coolmax pillows all for 270 pounds What a treat. got used to it from first night. No backaches or neckaches. Strongly recommend it.
    Very Happy
    Unbelievable bargain prices, professional and polite telesales staff, next day delivery included and 2 free pillows - I couldn't ask for more. Came across their website through a search engine and was incredibly impressed. I have already recommended to family and friends and every night when I get into bed I am amazed at how comfortable our memory foam mattress is. ...
