When browsing through FASHION FOR HOME's - http://www.fashionforhome.co.uk online store I came across a unique selection of design sofa beds - http://www.fashionforhome.co.uk/sofa, my favourite being the armless collection of sofa beds, they look exclusive and don't cost the world! I also believe that they meet all the factors listed above, comfort, storage and design!
Since I moved a little further away from my family I have been getting more regulard visits from them so I'm thinking about purchasing one of these to make their stay easier more me and more comfortable for them!
