    DO NOT Buy This Mattress

    Bought the model ​HARMONY LUX HLC-1000 EXTRA FIRM MATT-66KING in September 2021. Worked great for like 3 months, and then now it's sagging a lot, like sinking in 3 inches deep. I am 5'9" 195lbs, not super heavy. If now feels worse than a $200 Amazon memory foam mattress that I had before. Back pain EVERY MORNING now that it's sagging. I emailed customerassistance@simmons.com already. Hopefully they can help me get a working replacement that will last more than 3 months.

    Terrible mattress

    I bought the Beautyrest Harmony Lux Carbon extra firm mattress from a well-known bedding retailer. Less than a month after receiving the mattress it started to become as lumpy as the 8 year old mattress it replaced. Bedding retailer performed an inspection and denied the warranty saying this was "normal wear and tear". Essentially the mattress is worn out before I've made the first payment on it. Would not recommend this mattress or purchase another Beautyrest product again.

    Harmony Lux Carbon - Extra Firm - Classic Top

    This mattress is definitely extra firm. I chose it to help with my back pain from sleeping on a softer mattress that started to sag in the middle. After a few nights of adjusting to the mattress feel, I am sleeping better and waking without back pain.

    Really comfortable

    I have had this mattress for a few weeks now and I’m really impressed with how comfortable it is. I guess I didn’t realize how bad my previous mattress was until sleeping on this one for a few nights. It’s really supportive in all the right places and I wake up feeling refreshed and rejuvenated. I’ve also noticed my hips and back have felt a lot better since making the switch. I can’t speak to long term wear and comfort, but so far I’m impressed.

    Best Mattress Ever!

    I was in an accident a few years ago and ever since I've had trouble sleeping. I just could not seem to get really comfortable at night. My husband and I purchased this mattress and it was one of the best investments I've ever made. I love that this mattress is extra firm and provides lots of support. I am sleeping better at night and waking up less often! Definitely worth the price! I would recommend this mattress to everyone!
