Excellent customer service!

We are very pleased with our Murphy cabinet bed cube. All communication with Archic Furniture has been positive and prompt. The bed is very sturdy, and very attractive! The cabinet had very clear instructions for assembly. We would definitely purchase from this Archic Furniture again should the need arise. We are not full time in our new home yet so are unable to provide a photo. Thank you

I love my Uttermost product and I was very impressed that you called me directly to make sure I received the delivery. How much more professional can a company get! You are the best and I do a lot of ordering with other organizations.
Thank you.

David's review

The product was good quality from top to bottom and very easy to assemble.

David Jones
Queen Size Tri-Fold Gel Memory Foam Mattress
Queen Murphy Bed Cabinet in White

The bed is solid, well made and had no defects or blemishes. Delivery was quick, on time and the packaging was excellent. It was one of the easiest assemblies we have ever experienced. My husband was especially impressed with how clear the instructions were and the quality of the craftsmanship. We also liked that there were videos on the website that helped explain how to open up and put away the bed itself. The entire process was seamless. We have not slept in the bed yet - our first test will be when our son and daughter-in-law visit in a few weeks, however just lying on the bed it seems very comfortable.
