We are planning to buy 2 new sofas to replace our tired ones and are looking at the H&M Martini sofa. We would also like to get an ottoman but we're not sure which one. There are a gazillion choices! We don't want anything too big so that narrows it down just a tad. The seat height on that sofa is 18.5. Do we look for one with the same height? What about the feet.... I'm thinking they should be similar. Right? OK, then color.... we'd like to do Mesquite Saddle for the sofas. I'm leaning towards a different color for the ottoman. We have a lot of blue in our house, there is navy in the area rug.... how would a navy ottoman look? I'd attach a picture, but I don't know how.
