Perfect Mattress

The most comfortable bed I have ever had. The plush top is perfect and does not need any other toppers.

Cloud 9

This bed is like sleeping on a cloud. The kind you don’t want to leave in the morning. Best bed I’ve ever had

Heavenly Sleep

The best mattress that I have ever had. I sleep 6-8 hours without waking up now. I would definitely recommend this mattress and well worth the price!

Best rest yet

After years of sleeping in a firm mattress, thought we’d give extra firm a try, and boy what a difference. After three years still firm like when new.

Amazing Mattress

This mattress is truly worth every single penny. I have not gotten out of bed so easily in decades after a full night's rest.

Not so firm.

After test it for 18 months it's less firm than expected. I feel like when you stay in one position, the mattress adapts to your body's shape. It dips lower than expected, and I weigh 214 pounds.

Sags if used on an adjustable foundation

Sags within the first couple of days when used on an adjustable foundation. If I moved an inch or so to the left or right I was sleeping at an angle. This is an extra firm mattress. It was pretty unbelievable that this could happen so quickly.

Best night’s sleep every night!!!!

I am typically a side sleeper and prefer a very firm mattress. This Beautyrest Series One Extra Firm is exactly what I was looking for. I was way past due for a new mattress and it caused me to wake up with low back pain. I’ve had this mattress exactly 2 weeks and my back pain is 80-90% relieved.

Beautyrest Black Series 1 Extra Firm sags immediately

We noticed within a WEEK of having this mattress we already had body divets! The sag is unbelievable for an extra firm mattress! I am a stomach sleeper and wanted my mattress to be flat, firm, straight per say so that my back doesn’t arch all night. We had a 9 year old BeautyRest before this and it only started sagging slightly maybe 5 years in? I have a brand new TWO THOUSAND DOLLAR MATTRESS that now feels like my old 9 year mattress and I am livid. This mattress company must use cheap foam now, it’s asinine. Now we have to use our time to try and figure out a return/exchange with Rooms To Go where we bought it.

Extra Firm

My wife and I have been sleeping on the Beautyrest Black Series 1 Extra Firm mattress for about a month now, and we’re both really happy with it. We were specifically looking for a mattress with strong support, and this one absolutely delivers. It’s firm without being uncomfortable—great for our backs and overall sleep quality. We both used to wake up with minor aches, especially in the lower back, but that’s completely changed. The mattress feels solid and well-built, and it doesn’t sag or sink. Even though it’s extra firm, there’s a bit of cushion on top that makes it comfortable without losing that supportive feel. One of the biggest benefits for us has been the motion isolation. My wife is a light sleeper, and now she doesn’t even notice when I move or get up during the night. If you're a couple looking for a high-quality, extra firm mattress that prioritizes support and durability, we highly recommend this one. It’s been a great investment in our sleep.
