SKU: HARMONY_QUEEN Categories: , Tags: , ,

Produced with environmentally conscious materials. Strong wood and Steel make up the sofa bed frame while resilient multi-density memory foam makes up the sofa cushions. Available in durable fabrics that are easy to match. This Sofa bed wastes no space. When opened up it’s the length of a queen size mattress, for very comfortable sleeping. In terms of length, you cannot get any more compact than this. A space-saving sofa bed with a mattress that will surprise. Unlike a conventional fold-out sofa bed that uses springs and metal bars which you would normally feel, the Harmony uses a tri-fold memory foam mattress. Typically, a coil mattress when bent and slept on will distort over time, which leaves you with the infamous uncomfortable sleep so many associates with a sofa bed. The Harmony is a game-changer not only by opening up to exactly the length of a queen bed but also by providing an even mattress that feels seamless.

You deserve a better sofa bed experience.

Not only did we create the most compact sofa bed design in the world, we also made one that is incredibly comfortable and will redefine how you think about sofa beds. No bars or coils just an even sleep.

Couch bed does the job but shipping sucks!

First off, I ordered my couch 10/22/22 to have it by Thanksgiving. I was told it would arrive in 2-4 weeks. I received the bed December 13th. The box arrived mangled and completely damaged! The guys delivering were unapologetic and could care less. Luckily the couch was unharmed. I put it together and it is functioning as intended. Unfortunately, I might not buy from Expand again due to the shipping company they use Metropolitan Warehouse.

Sorry about the outer carton damage and we are glad it was all safe inside and works as expected. Metro is a company we rarely use, but regardless they should have done better and we are sorry about the delivery experience.

Great looking sofa bed for a small space.

This is the perfect size for my office/guest room. I love the look of the faux leather, it fits right in with my decor and is super easy to keep clean.

Edward Min U (Honolulu, US)
Stylish and Comfortable

We love it! Guests have said it’s comfortable to sleep on and it looks so stylish in the room! Plus super easy to set up, use as a bed and put away as a sofa. Great purchase!

Laurence Turner (Phoenix, US)
Nice sofa bed

We’ve used it a couple times already. Extremely comfortable and very importantly it fits in the space perfectly. I hope it will be durable over time. Seems well built.

Great couch great bed

We got bought the Harmony King Sofa bed to replace our couch and enable us to have family stay over. It’s great! We’ve never bought any furniture online before so this felt risky but we were able to visit the Vancouver office to try out the couch for comfort. Its is very comfortable as a couch and as a bed. The memory foam feels quite firm but suits us and you do sink into it’s memory foam-ness. We love the size of the couch seat, nice and roomy. The back can be set in a variety of angles to suit lounging preferences which is nice. It take a little practice to open it into a bed but after a few times it’s smooth and easy. It’s nice that it can be a single bed without unfolding at all because the seat is long and deep. Half unfolded makes a good double bed too. Option are great. Over all very happy with this couch which suits are small space very well and isn’t overwhelming in size.
