Similar to a chaise longue, a day bed lets you lie flat, rather than gently recline against a back support, so they're a great addition to have for the occasional overnight guest, or for those who like the odd afternoon nap.
The latest styles would look as good in a smart sitting room, as they would in a guest room or a study that doubles up as a guest room, particularly if you require a slimline bed that can also serve as seating.
The Lubi day bed by Kurt Brandt for Softli and the Two Pack day bed at Loaf both have deep mattresses that are more than enough for a good night's slumber - and whilst different in style would look great during the day scattered with your favourite cushions.
The Maxime at Johnathan Adler is a rather more glamorous affair that would work well in a bay window or quiet alcove, while the Turn from Ferm Living, the Caterpillar from Made and the Fusion from Bo Concept, perched on their slim legs would provide stylish seating in a modern living space.
