I couldn’t decide between the medium and firm. I chose the medium, and I’m glad I did. Last night was my first night on the new mattress. It’s very firm and I think it may take some time to get used to since I was on a plush before.

[This review was collected as part of a promotion.] It's very comfortable. It doesn't get hot on your back when lying for a long time. I no longer have back pain when I wake up every morning. I'm so in love.

I thought this was the best mattress ever after the 120 day sleep trial but 10 months after purchase already have body grooves and my back is hurting again.

Purchased this mattress in a king 4 years ago. Needed to update our guest room and pitched another one. Hold up great and ultra comfy. The side and end handles make rotating easy!

I have had my black series 3 medium mattress for only a week but I love it and it’s already improved my lower back pain. I was using an older 100% latex mattress which has lost its “give”, so this black series 3 hybrid is a much welcome comfort!

[This review was collected as part of a promotion.] After replacing my old mattress with this; I've slept the best I have in years. It's literally a full body hug every night. Not too soft but not too firm either I'm so happy with it

I exchanged two mattresses to finally end up with this one… So the third time is a charm! I needed something that still had cushion, but was also more supportive and this is perfect

Very comfortable mattress. After 8 months, mattress sinks on both sides and is starting to cause discomfort. No visible signs of sinking once not on the mattress anymore.

Can't wait for our first nights sleep on our new Beautyrest Black king mattress. We briefly tested the firmness of this mattress in the store and looking forward to many years of comfortable sleep.

I feel like I am falling out of bed every night because the mattress slopes down significantly. The mattress inspector came twice and said there is a. significant slope. I have asked for a replacement but have been denied two times.
