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.

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

Mattress is as hard as a rock. Trying to get a hold of someone to return it has been an absolute nightmare. Sam's customer service is awful. Serta's customer service is worse. Call and get a message that they are in a team meeting and then call disconnects. Absolutely horrible. I don't think I will continue my Sam's membership after this terrible experience.

Looks good and comfortable but after 6 months, we began to feel a depression in the mattress where we each slept. After 9 months a depression where we slept was noticeable and we could feel a ridge in the middle of the mattress that is now even more pronounced after 1 year. It was comfortable the first 6 months, but after the depressions were we slept and the ridge formed, it became less comfortable. The ridge in the middle makes it difficult to sleep near the center of the bed. We are not heavy in weight, or overweight, and that makes us wonder if the material used in the mattress is very good material. We would not purchase again nor can we recommend this mattress or the material used to make it. The original coil mattress we had originally lasted over 30 years and was very comfortable until a spring broke. This mattress did not last one year.

Mattress seems to be good but the delivery experience was HORRIBLE. It took several weeks for it to be delivered after purchase, which is fine. We had the “white glove” delivery which was supposed to include bringing in and setup. We received notification of delivery date and timeframe along with instructions on how we needed to be ready for setup which we agreed via text and email. We received confirmation again the day before scheduled delivery and were ready to receive delivery the next day as notified. Approximately 1130 pm, the night before our delivery, we receive alerts on our security cam and hear a large truck driving away. We look outside (it’s raining) and the mattress was left propped up against our garage door. There was no knock on our door and doorbell wasn’t pushed. If we didn’t know that, it would have likely caused damage to our garage door if we had opened it unknowingly. We have the delivery saved on our security cameras. We were able to pull it inside ourselves but this would have been a rough situation for someone that is elderly or disabled. We notified Sam’s Club the next day and was told we would be “compensated” for the inconvenience. It’s been over a month and still nothing. We call to follow up and Sams Club indicates the the delivery company will compensate and when we speak to the delivery company “RXO” we’re told that sams club will compensate. At this point, we realize nothing is going to happen. It may be a great mattress but until Sams gets a new delivery service, I would definitely avoid purchasing from them unless you enjoy a runaround which includes your new mattress being left outside at night, in the rain.

We bought this mattress, King, medium, Aug 30, 2023, and debated returning it after about 3-4 weeks as it started to sag where we sleep! I am 6', about 220, and wife is 5'2" and about 130. We kept it until the sags got so bad we decided to get another different bed! High, very hard lump all down the middle of the bed! This bed has a 10 year warranty and a 100 night trial period! When you get beyond that 100 night you are pretty much on your own! After 3 'chat' sessions with Sam's return folks, we got them to agree to take the mattress back. They put us with Serta, who makes Simmons I guess, and that lady was adamant that we could not return it unless the matter was approved by higher ups! She kept going back to the 100 night trial being past! We bought a more expensive mattress from Sams, and at the moment we are assured by a supervisor that Sam's will refund our money! But, the one in this ad sagged significantly where we sleep[. After about 4 months it started to make a noise, 'scrunching sound' when I moved, like rubber rubbing against other rubber.
