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.

The Perfect Sofabed

We were on the hunt for a sofabed that fit for our small space and struggled to find one that was small enough but didn't compromise on quality/comfort. Most of the ones we found that fit the space were cheaply made and didn't look like they would be comfortable to sit on, let alone to sleep on.

Super glad we came across this one from Expand Furniture. It fits perfectly in the space and the mattress is great quality for a sofabed. Assembly was super easy and love that they are a local Vancouver company.

Awesome sofa bed

Looks great, very comfortable to sleep on. The transformation process could be smoother, especially extending the lower part. But overall, I’m very happy with this purchase.

Used Daily

We bought the twin size to use daily as a chair and sleeper. We have used it that way since we got it 2 months ago and it is great! Sleeping-wise it is very comfortable and firm which is preferred for the user. The back angle versatility when using as a chaise is great. It reminds us of the plastic beach loungers from childhood (even does the clicking). The twins size is wide enough to keep the arms on (even though they are removable) when sleeping. The only difficulty was figuring out how the mattress fits onto the frame when first setting up. It took a couple of tries and we had to look online to puzzle it out.

Beautiful Functional Sofa Bed

The Harmony Queen Memory Foam Sofa Bed is beautiful and functional. I've had two sets of guests so far and both said it was super comfy for sleeping. The conversion from sofa to bed and back again is very easy. The video showing how to set it up could have been better, but it's not hard to figure out. I also had a little concern with the corners of the back pillow cushion fabric casings (one being more squared off and the other was more rounded), but the customer service department sent me two new ones right away. Delivery (from Vancouver to Northern California) was about 2.5 weeks and I was well informed as to its status en route. And delivery was super cheap which I couldn't believe since it's out of the country. The Box (which was huge, like 5' x 5') was in great shape on arrival and the gentlemen who delivered it were lovely. Though the box was huge, the parts inside are all cushions, mattress, and the base and arms, and very well packed (i.e., make sure you have lots of room in your recycle bin). The base was manageable for two medium strength women or men to move. This is a great company with innovative high quality products! I would definitely recommend!

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.
