I had purchased a Malm queen bed frame last year and had to purchase the added metal frame piece and wooden slats that the matress sat on. I had no problems until about 3 months ago when I was getting up from my bed and the one side collapsed in. I picked up the mattress to find that the wooden slats had slid off the frame and bent the metal supports underneath. I tried fixing it a few times only to have the same result. There is a gap in between where both sides of the wood meet in the middle where the metal support beam is and for some reason i think this is causing the problem. I had gone into the same Ikea store for other items and asked the women in bedding how i would get replacement wood and metal supports since obviously mine were defective. She told me to check at customer service who rudlely told me I would have to purchase replacement wood and metal supports. After spending an addional $50 on top of the original purchases of furnature that were over $600 I went home and took off the bent metal supports and wood. I tried putting the new metal supports on only to find they were too long and that the store had not given me the proper screws to replace the pieces anyway. I decided to try the wood without the metal supports and it fit like the old wood had. After testing the bed the wooden slats again slid off the frame. I called the store I had purchased from and they told me my only option, again, was to purchase new supports and wood. Why would I spend another $50 on the replacement parts if it was just going to do the same thing?? I love all my Ikea furnature and this is the first time I have ever had a problem with my items. I don't feel like after all the money I spent on the furnature the first time I should have to keep buying replacement parts that don't work! I love Ikea furnature but I don't think I will buy anything from them again. I would rather pay more for furnature then waste my money with parts that break and are not fixable.
