Less than 6 weeks old and already a sinkhole!

I had high hopes for this mattress. It was super comfortable right from the start. Today as I was changing sheets, I noticed a nice sized divot in the middle of the mattress where my hip hits the bed (side sleeper; 170lbs). Not sure if the bed is molding to my shape or if it will continue to sink. Very disappointing thus far. I know getting a manufacturer to honor a mattress warranty is rarer than finding a unicorn.

Sinking

I'm trying to get in touch with the seller on returning this if anybody has any information on how to do so. I bought this bed on 1-8-17 and got it about 3 weeks later. It's now match 3Ed and there is an obvious sunken area on the bed. I read in another review that the seller said there was no reason that should happen. It was comfortable, but it is sinking and I would like to return.

Firm and Supportive

Coming from a Sealy memory foam mattress that sagged in less than 6 years, I was looking for a coil mattress with good support that wouldn't break the bank. After testing 15-20 beds, I decided that “cushion firm” seemed to describe what I was looking for. Sadly, this particular mattress was not available to try at any local clubs, but I took the leap and am glad I did! My body took three days to adjust - it is pretty firm - but I am satisfied with the comfort and construction and feel my back is well supported by this bed! For reference, I am 6'4”, 260 lbs, a back sleeper, and I have been sleeping on the bed for 2 weeks.

Constant Pain

Purchasing this mattress has been the worst mistake I ever made. I wake up in constant pain every night. I previously had the Serta Kerrington mattress and wanted to get that same 1 but Sam's Club no longer carry it and I was told the Castleview was it's replacement and comparability was the same quality. Clearly that's not true or I wouldn't be crying daily. If I could return it I would.

SUPER FIRM 1-2

I received the mattress 3 days ago and already looking for a replacement. It's so hard it gives me lower back pain from sitting on it for an extended period of time. If I lay on my side with more than one a pillow, it gives me neck pain. If you want to sleep on a board... BUY THS!

A little disappointed

I just received the set a few days ago. It was a hassle dealing with the local delivery company and I ended up having to wait an additional week in order for me to be home from work with an all day window open. My initial thoughts when I received the mattress were that it was rock hard. The pillow top is not soft feeling at all and does not seem to provide any cushioning for me. The mattress is extremely firm and does not "give" at all. I had called the serta hotline twice before ordering and asked 2 different people if the mattress would feel hard and was told no, the support would be firm but the pillow top would make it soft at the top. I was really upset thinking that I wasted my money and waited close to a month (for delivery) for nothing. I went out and bough a 1.5" mattress topper. With the topper on it, it is more like what I expected- a firm support, but somewhat cushioned feel. I'm still a little bothered that I had to go out and spend more money for the topper and a new cover that would fit it, but it seems like it might be less hassle than dealing with a return and reorder. Especially since the delivery company in my area was not good at all.

18 months and has sunken spots

I purchased this mattress in November of 2016, it was delivered December 10,2016. I rotate it every six months and there are already sunken spots from where we sleep. Not the best quality, cant say it will last 8 years which is usually when you should replace the mattress. Wouldn't purchase again or recommend

Exceptional value for premium bedding

We wanted to upgrade to a king mattress but didn't want to pay the high price for better quality, nor did we want to sacrifice comfort for value. This mattress is without a doubt the best of both worlds in quality and value! Would highly recommend to couples who tend to prefer different types of cushion (firm vs softer). This pleases both preferences! We cannot vouch for long term durability as it's a fairly new purchase, but we expect alot with being a Serta.

Cal King Firm

I bought this bed in good faith, but it's the Worst bed I have ever had in my life time. The pillow topper on this is Cheap, pretty much like it really doesn't have one! I have bought a three inch foam topper to put on it but it's still like sleeping on a brick. I like firm beds, but I feel like this is a poorly made bed and made very cheaply. It's not worth a penny. You couldn't give it to me. The fellows that brought the bed were great and did take the old bed. What can I do, I don't want this Bed!!!! cc #SamsClub

Nice mattress , firm, size less than specified

Received this mattress set 2 weeks ago and I installed it last night. Noticed larger gap than normal between the bed frame and mattress sides. After measured it I found the width is less 1.5 inch than King size 76" standard mattress width. I received no answer to my question regarding the size of this mattress being under the standard and the listed size on SAM'S Club site(W=76"). I'm thinking to return it in place to finish the bed platform, because now is visible all around the mattress. I'm not recommend it because of the narrowed size, the mattress quality is OK.
