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.

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.

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!

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.
