Sofa bed vs. day bed

I've decided! I'm finally getting rid of the ugly sofa bed in our guest room. It's not even a proper sofa bed, but just one of those ugly grey metal frames with a folded futon on it. Uuurgh...

I'm thinking of either replacing it with a proper sofa bed - proper meaning one that actually looks like a normal sofa when it's not used for sleeping in - or a day bed.

 I've been looking around online for some inspiration, and found quite a few that i like. Now the question is, sofa bed or day bed?

The two lifestyle photos in the collage above are from Pinterest, the beige sofa bed is from Home Essentials through Catalogues247, and the lilac 2 seat sofa bed is from AHF.

This gorgeous white metal frame single day bed is from ASDA. It looks very girly in this picture, but with it being of such a simple design you can style it how you want. All you need is a throw and some stylish cushions.

Although the dream is to purchase this white wooden Hemnes day bed from IKEA. I've had my eye on this for ages as it's so clever - you can eiter use it as a sofa, a single bed, or you can pop up another bed from underneath so that it turns into a double bed. It's just a teeny bit expensive...

Wouldn't it be funny if I went for an olive green bed to match the focal wall of my guest room? ;)

Nah, maybe not... hehe.
