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.

good chair

Good-looking chair, and working well for our needs so far. No instructions sent with the shipment to attach the arms - that was a little frustrating - but other than that we're pleased.

Hi Jennifer, we are now sending video guides of the installs as a backup in case a manual is somehow missing for a future customer to prevent possible inconvenience. (they should always be packed inside!). Glad you like the Harmony Sofa Bed.

Comfortable and great service

Perfect fit for my space

I did a lot of research before I purchased the Harmony Queen Sofa Bed from Expand Furniture. I needed a quality product for when I have out of town guests. I had space constraints as well as narrow door way widths. The sofa has met all of my expectations. The box fit easily into the room and I was able to get it assembled within 30 minutes. I also ordered the matching ottoman. I would highly recommend this company and product.
