Extra firm is correct and that is what we wanted after a firm mattress not providing good support after a couple years. Of course, we will have to wait and see how it holds up. The construction says more support in the middle and that is what I need. For comfort we have a basic bed topper and heavy matters cover with some softness. That has worked well for both a heavier and lighter weight person. Great side support and solid construction.

This mattress is so incredibly comfortable. I have back issues and I have Ben resting so much better,sleeping soundly and not nearly as warm as our other mattress. This is definitely a great value!

I bought this after trying another mattress which said firm but was not firm. Me and my wife are extremely happy with this mattress. It provides great support, does not sink in and is firm. It also has small cushioning kind of top which does not make it feel like a rock. Definitely recommend this to anyone looking for a good FIRM mattress.

Still trying to get used to this extra firm mattress. My husband is happy with this purchase, however, I am the one with more back and neck issues and wanted to get rid of our other mattress, that was just over 3 years old. It was one of the memory foam kind, and was great for about 6 months, but then my back issues got way worse than they ever had. The mattress at that point wasn't supportive enough. Anyway, we didn't go anywhere to test the Beautyrest Silver Charcoal Coast Extra Firm King Mattress...I just placed the order, because I knew I needed the support...but now it's almost too hard. My mistake in not trying to locate one and try it out first, and now we are stuck with it. Like I said, my husband is happy with it, even though he said he still gets hot at night, but not like with the other mattress. We may eventually get a memory foam topper for this bed for my benefit. I hope that it holds up longer than the last one did of only 6 months before we were ready to throw it out.

Comfortable mattress, good value. Have in our guest bedroom Would have given it 5 stars but about a week after it was delivered when we went to make the bed, we noticed there is a 4” portion where it missed being sewn together on the underside of the mattress at the seam. Quality control should have caught that.

This mattress was great—until it wasn't. About 3 years in, it started to noticeably have sagging on both sides. By year 4, it was completely done. The back pain is excruciating. Disappointing for a mattress that was sold as lasting 10 years.

Purchased this mattress that was delivered 11/21, and I am not pleased with the firmness. Owned a tempurpedic since 08 and it had gotten too soft. Used plexiglass/lexan to help ease my back pain for several years, and looks like I need to add it to this one also. My back has ached since purchase of this "not so extra firm" mattress. Also the delivery date was NOT what was advertised "before" purchase

I will never order from Sam's online again. We received a defective mattress and have spent hours over several days trying to connect with Sam's Online Customer Service to get the issue resolved. We are asked for our phone number and promised to be called back if we get disconnected. We NEVER get called back and always just sit on hold forever and never get reconnected Each new person we talk to has a different story of what is happening with our case. We were told at one time that a new mattress was being shipped - not true. Another time we were told that the old mattress was going to be picked up - not true. We finally had to contact Beautyrest and they are sending us an email with information on how to send pictures and request a replacement (something the first 3 people we talked to at Customer Service promised to do but never did). Update: It has been over a month and we still have not received a replacement mattress. We have scheduled a delivery twice and both times we got a notice of cancellation a few days prior because the product had not been delivered from the warehouse. It has been a nightmare experience.

I did not see that the item was not available for return until this morning. It has been less than 24 hours of having the mattress and I hate it. If I can't have a return, can I please have some sort of an exchange?

This mattress is NOT ultra firm. Yes, they've branded it as ultra firm but there's a layer of "plush" soft material on top of the firm part. The problem is, this top layer is super low quality. I'm a 220 pound guy which isn't overly heavy and Im literally sinking 6 inches into the mattress a week after purchase. There's a valley where I sleep already! So if you need a firm mattress that you actually sleep on top of, and not sink into, look elsewhere. I'm surprised how low quality this mattress is. Ignore the reviews saying how great this thing is... It's not!
