Smart Design with Style and Charm!

Love this couch…looking for a more durable stylish option and discovered this gem. Former traditional spring style sofa bed owner fully converted to the Expand Style support system. No more uncomfortable nights and ample room with the King Size luxury.

Love my Harmony Bed Sofa

I recently purchased the Harmony Sofa Bed and I could not be more pleased. The couch is excellent, incredibly comfortable and the perfect fit for my apartment. Expand were excellent to deal with; very responsive to all my queries and ensured timely delivery which was really important for me. The installation instructions were clear and easy to follow. I am not typically good at this type of installation so having such good instructions allowed me to set it up on my own with no issues which I greatly appreciated. Highly recommend.

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.
