Covers great, but work is required for the new look.
My Karstad sofa has reached the end of the eye-pleasing life and rather than tossing it, I decided to get new covers. Since Ikea had long discontinued it (so much for so many years of warranty, thanks guys) like most of you I had to find the covers elsewhere. I ordered a few pillow covers in colours I thought I would like for the sofa and this way I would know exactly what it would be like once you start using it. I picked the Petite Titanium Gray in the end (finally the orange cat hair blends in :)). Here is what I did not know... the covers fit slightly bigger than the original one (foam and filling has been compacted over the years of use hence it does not give you that new sofa look). When I just changed them out, I was rather disappointed. I did some research (big thank you for Mark's upholstery videos on YouTube) and got to work. First, you steam the foam sides on the cushions and, it will bring it back a bit, closer to the original size, then you add batting to fill in the space. For pillows, you have to open the inside part, pull the stuffing out, fluff it out (rip it to shreds) and put it back in. Start from the middle section, shred, fill and move on to the next one. I added a bit more just cause I like them firm). Got 4 cheap pillows from Ikea for that. Once this process was done, my sofa looks brand new, no sagging. The quality of the covers is great, love, love, love the colour. I think you will be very happy with the covers if you are willing to put in the work.
