We have the Black Series 3 Medium Prime. It surpasses the firm mattress we had previously. No regrets.

It’s only two days but it is very firm. I’m wondering if the rang up the correct mattress from the floor.

So far the mattress is still stiff but it is starting to adjust to my body. It is comfortable and helps my back. A very good mattress.

This mattress is incredible! I am sleeping better than ever! Perfect support and temperature. You won’t wan to get out this bed!

Very Comfortable and supportive, tried a lot of mattresses but once we tried this one the other felt just OK

We sleep on our new mattress for the first time and it’s felt like sleeping on clouds. Love the experience with this mattress

We went through four mattresses on our way to finding this one. By far the most comfortable mattress I’ve had.

Replaced a world class mattresss from 9 years ago with the series 4 black and have never had a better night sleep!!

Beautyrest Black Series Three has been great for my lower back pain. Having much better night sleep now.

I love the fact that it's both soft and firm, and the sturdy sides are perfect for sitting on the bed.
