Series Four 17.5" Firm Summit Pillow Top

Not sure how you saw the quality of the BR Series 4 doesn’t hold up? Those mattresses came out 1 year ago in 2024 and are pretty much an entirely new design and materials.

I returned mine for comfort reasons. But just saying you can’t really claim longevity issues on a 1 year old mattress

I work at Mattress Firm and we have the Beautyrest Black series on the floor. I actually see a lot of back and side sleepers (especially with lower back pain) do well on it. It has strong coil support for the low back but still enough cushion on top for shoulders and hips, and it doesn’t have that “stuck” memory foam feel. Also totally fine on a solid platform.

Because each series literally adds more materials + more advanced support tech + more cooling layers + more labor to build. So the cost to make it (and the performance) goes up each level.

It’s only good for about 4 years though. First one was replaced just at 4 years, the centre caved (we are 130lbs & 180lbs and do not sleep in the middle of the mattress) and beauty rest warrantied it with the same mattress (they change the mattress name, but it was the same mattress) and right at 4 years, now it’s caved again where literally no one sleeps. It has to be by design. Beauty rest is absolute garbage. Thinking about a bed in a box quite seriously at this point

$800 Beautyrest innerspring mattress, firm. No idea what model. Bought it the furniture store 8 years ago when we bought the bed. It’s getting time to replace and I’ll just be looking for another basic spring mattress. I’m not very particular. As long it’s firm and springy, I’m good.

On our 2nd Beautyrest Black (firm king) because the first was replaced under warranty when it sagged and this one is sagging, too. We both weigh less than you. I regret it. Felt great new but by 6 months in both times there was a huge hump in the middle and deep depression where we sleep. *GONG"

My FIRM Beautyrest Black is amazing!
