Are you putting your back out constantly dragging the z-beds down from the loft? Nearly passing out blowing up air beds? Nearly losing a finger while putting up the camp beds? Before you keel over from all that hosting, meet the John Lewis sofa bed that's going to change (possibly save) your life...

If you are seriously on the hunt for new sofa bed, make sure you head over to our round-up of the best sofa beds. You'll also want to keep an eye on our Black Friday deals round-up, as we're expecting lots of sofa beds to feature this year.

So what's so special about this John Lewis sofa bed? Well, the Duplet sofa bed is soooo much more than just a sofa bed. Its many forms mean that not only will it take up much less space than the previously mentioned z-beds and camp beds, but your guests will have a more comfortable night's sleep to.

So, let's take a look at the Duplet in its many forms...

Probably the form your Duplet will take on daily is as a sofa or a daybed. One of the best things about this versatile piece is that it doesn't take up a load of room because it's not a traditional sofa bed.

This means it needn't be kept in the living room as a replacement to your normal sofa and could instead be kept on a landing, in a hallway, or in your bedroom depending on the layout of your home. Then, it can simply spring to life whenever you have overnight guests.

A kingsize bed. Not a just a double, a KINGSIZE. Lucky, lucky guests. Part of the appeal of The Duplet is that it unstacks. And if you pop each of the parts next to one another you get a massive, really comfy guest bed. 

The mattresses are foam too, meaning they mould around the body for a really supportive sleep.

Perfect for when you have two guests who would rather not have to share, this John Lewis sofa bed can also become two single beds. We love it because it gives you a bit more flexibility with where your guests can sleep and you could even pop the two different pieces of the Duplet into different rooms to create two makeshift spare bedrooms.
