When we wanted to buy a king mattress we couldn't make a choice because there are so many kinds. We looked at the tag of the queen size we had been sleeping on for over 10 years and it was Royal. We looked where to get another Royal and this location was not far from us. We were led through the factory to a showroom where we tried out mattresses. We chose firm pillow top. They took a week to create it and deliver. It's not pillowy it's firm. It's been very good for our backs.

Not the easiest place to find in the world, but if you want high quality bedding at the best price anywhere, this is the place you'll want to go. Sales staff is great. They're very helpful, but they don't hover or put the hard sell on you. I really like that. Delivery service was spot on. They showed up when they said they would, set up just like I wanted, and made sure I was happy before they left. Highly recommend.

I have purchased beds for years with also called City Mattress of Haltom City, TX. I bought a mattress that is on the bed at my sister's house and also bought 3 adjustable beds for my house. I received excellent service, delivery and set-up. I just bought the last adjustable bed 4/16/2015. It is a Queen S-Scape Adjustable base with Queen Royal Touch Gel Mattress. The bed is wonderfully comfortable. No stress pains in the mornings. I would recommend this company anytime for they have given me excellent service.

My son and his wife had Royal to make them a mattress for their camper. I slept on it and it was great. So my wife and I had Royal to make us a mattress for the bed of our pickup 4 feet wide and 80 inches long. It was an inner spring mattress firm and it was wonderful. If I ever need another mattress I'll go back to Royal Sleep Products. Thanks, Royal Sleep Products.

We purchased a pricier futon mattress from Royal Sleep because I thought a quality mattress was important. The mattress was not worth half of the $269 we paid. The mattress came with stains and holes. I tried to get the stain out, but it wouldn’t come out. I thought I would look at the tag so I would know what material the cover was made of and see if a different cleaner would work. The tag said made of all new materials consisting of... the rest of the box was blank. The company took $69 off the futon and sent a new cover, but makes me worry how well the inside will hold up when everything on the outside is messed up.
