Straight No Chaser, Comfort Sleep!!

This mattress is, “da’ bomb!” Folks, if you think I’m fibbin’, get one! It seems to re-align sleeping posture, I miss work, on purpose to stay on this mattress! I removed the bedding to get model number for warranty- 10 years limited.

Great mattress - beautiful, well designed, and very comfortable

Love this mattress. Beautiful design and very comfortable. It has good support and a lovely cushioned top. Independent coil design with five comfort points is ingenious. We looked at every other brand, and this mattress was by far the best-designed and most competitively priced one we could find. Highly recommended.

The best sleep in years

I had my other mattress for 15 years, and it was great until the last week. I knew I had to replace it. I went to Mattress Peddler as I had been there when friends mattress shopping and was impressed with the professionalism and kindness of the owner. I love the mattress I purchased. Just the right firmness. I am so happy
