Worse mattress I have even purchased or seen and in a terrible state after just 15 months however started going after just 4 months and I have thrown away mattresses 10 years old in better shape and condition. Within 4 weeks a sharp piece of spring pieced through the side cutting myself servel times on this, tried to bend it back into place however kept coming out. The materess looks absolutely battered all the side have sunk and the middle is so mis shaped its rippled, Being small and very light i am suprised I can make an ident into any mattress. After suffering back problems it come to the stage now I have a little spare time after a busy year I have to purchase a new mattress after only having this one for roughly 15 months and certainly fell for the gimmick of a flash sale which I believe was for 24 hours only-Mattress that was apparently worth £550rrp which I think was roughly £349 on sale at the time down to £99-Only the king size mattress every other size in this still was £200+ if my memory serves me right, Bargain I thought!! That was the 1 st mistake.A very big mistake Upon thinking I got a bargain I ordered 2 thinking what a super price even got 5 percent discount as it was over £100, Come delivery day only one turned up which knowing what I know now is a blessing - I was offered the 2nd mattress to be delivered another day but declined this as I was busy with work and in fairness bedworld refunded me the monies for the 2nd mattress and I received this within 4/5 day and still hourned the 5 percent discount even though my order was under £100 which was good on them even though its pennies they didn't have to. I spoken to live chat prior to leaving negative feedback as I thought I made bedworld aware of the situation and give them a chance to rectify it however Kevin has said nothing he can do as it's out of warranty which I asked how long is this warranty he stated 12 months,-This is obviously the expected time scale they expected the product to last which is pretty spot on after 12 months I started getting bad back from the mis shaped mattress starting to fall apart. Kevin was keen for me to state I had this matteress at a very heavily reduced price as its worth £550 which makes it worse as the mattress in reality wasn't worth the £94 paid. Moral of the story - Don't fall for there flash sale gimmicks like I did making an impulse buy, Don't believe the rrp or the price they state on their website - The price you pay is the quality you get and if a firm only offers a 12 month warranty I question why? Simple buy cheap buy twice-Don't be fooled by the description like myself. Hands down the worse product I ever bought and something as important as a mattress I suggest people steer well clear and used a firm that will give you a 5 or 10 year guarantee. Feed back left after time to give a true reflection of the quality
