The World Class level 3 medium firm tight top is the right mix of firm and soft; firm and supportive but with a lightly cushioned top. I don't sink into it and can turn over easily yet my spine feels aligned and hips, shoulders and all joints are comfortable and supported. The mattress is pretty heavy and has a more premium feel.

That's pretty much it. Not comfortable, expected a mattress with a bit more "give" to it. Wanted something with good back support, and can deal with a breakin period, but this after a week still feels overly stiff. I'm also told that it can take a while longer to break in so I'm going to give it a few more days.

Uncomfortable, bumpy and lumpy. It does not offer any support or pressure relief, on the contrary, I feel more pain in the morning than when I had a cheaper mattress. I am regretting purchasing this mattress and will never buy a Beautyrest mattress again.

I love how firm and supportive this mattress is. It gives me the perfect place to drift to sleep every night.

Excellent mattress

the extra firm is hard as a rock it feels like concrete. I am not saying this is not a good brand I just think we ordered the wrong one for us

My teenage boy is 6’1” and still growing. This mattress will hopefully provide excellent support for him.

This mattress is one that convinced me to stick to Non-Firm when it comes to mattresses. I'll stay with Simmons for my next mattress, but I hope they suffice.

Day one, the boyfriend said it was super firm. I replied that just shows how mushy his old mattress was. So far it’s super comfortable and I’m hoping will alleviate his lumbar issues, now that we have this new mattress.

We shopped around looking for a firm mattress and did not find one that met our needs. That was until we came across Beautyrest's World Class Level Three Extra Firm mattress. This mattress truly is firm and met our stringent needs for a quality and supportive mattress.
