The Precision Support System offers 40% more support coils compared to Harmony models for even more head- to-toe support across the entire mattress, so you and your partner sleep undisturbed.

Infinicool Lux technology helps you stay comfortably cool all night with its breathable, moisture-wicking fabric infused with cooling fibers and plant-based cooling technology. Pressure-relieving foams help ease aches and pains while also creating airflow throughout the mattress. Step-ups feature bio-charcoal cooling foam and 2X the memory foam enhanced pressure relief. All models are crafted with a lofty, quilted top, making them perfect for those who prefer a lifted feel and want rejuvenating sleep each and every night. Collected from areas within 50km of coastlines. Plastic bottles collected vary by model ranging from 60 to 100.

  • Comfort and Support
Style: 13" Hybrid Medium Size: King
I chose this mattress based on reading reviews, looking at lists of 'Best Mattresses', and knowing I wanted a hybrid mattress. I knew I wanted a mid price mattress...not the cheapest (foam), nor the most expensive. Beautyrest came up repeatedly in my searches and questions. I am VERY pleased with this choice. I have a pet sitting business where I stay in clients' homes and I knew I didn't want an all foam mattress. I hate the 'puddle effect' many foam mattresses form which makes it difficult to turn over or move freely and the foam tends to trap body heat. I have slept on several Beautyrest mattresses (of indeterminate style) in my clients' homes (I ask the brand) and have been pleased with the comfort and support of this brand, in general. From there, it was just a matter of trying to determine which choice of Beautyrest best fit my needs. My husband likes a softer mattress than I do, so I add a topper, and this mattress satisfied both of us with its' support and comfort, without being too firm, or too soft. It is cool and does not trap body heat. Both of us are happy and sleeping well! The white glove delivery (purchased separately) was seamless and within the time frame selected. I was surprised and very pleased. Super easy, efficient, and right on schedule! Five stars for brand and delivery! ... show more

  • The Best Mattress
Style: 14.75" Medium Pillow Top Size: Queen
This mattress is outstanding! We had one for my mother who was 86 years old and she loved it. When she passed, my daughter took her mattress and I went and bought the exact same mattress so comfortable no back aches no leg aches. It’s wonderful..

  • Prison Bed!!!!!!
Style: 13.5" Plush Size: Queen
This bed was the worst I ever purchased. Hard as a rock. No where near Plush. BeautyRest usually have good beds but this was not one….The return process was a headache… Took two week to have it picked up…. The bed was picked up October 25 and I was told I wouldn’t get my money back until Dec. In my head i’m thinking thats way to long. Some how my return got lost in transit so I had to call amazon to get my refund faster…. Thanks Amazon.. ... show more

  • Excellent mattress!
Style: 14.75" Medium Pillow Top Size: Queen
This mattress is perfect for us. With the old mattress we would wake up with considerable back pain. Everything is a serious upgrade. It is considerably thicker than our old mattress so it takes getting used to get in and out. But that's what makes it so comfy...

  • Bad quality
Style: 15.75" Plush Pillow Top Size: Queen
I purchased this for a vacation home and wanted to wait a bit to try it out before reviewing. This mattress is not up to par, especially by Simmons standards, or what used to be their standards. It is way too soft sinks in the middle and you can feel every movement of your partner, making it difficult to get good sleep. Very disappointed, considering the amount of money spent and the trust I put in a "quality" mattress company. ... show more

  • fantastic mattress!
Style: 14.75" Medium Pillow Top Size: Full
my last mattress was a beauty rest, but 2009. went back for another one and this one is very nice, everything as described! IMO, best mattress! I compared mattresses on the beauty rest website. Amazon had the best price, and the delivery service included unpacking and hauling off the packing. (request the special delivery service as you order your mattress, free when I bought this). thanks amazon! ... show more
