Sags in the middle

The mattress started sagging in the middle after only a few weeks. Causes me hip pain if I sleep in the middle. If I sleep on the edge of the bed, it's fine. There's lots of support around the frame of the bed but not much in the middle. Turning doesn't help, either. Probably ok for a guest room.

Worst

I placed an online order for this mattress on Sams.com. I received a phone call from the delivering company, Statewide Transportation informing that the delivery would occur on Sept. 15 by 6pm - NEVER HAPPENED!! I did not receive a call letting me know why the delivery never happened or anything!! I had to call the delivery company myself including my husband to find out what was going on - worst customer service I have ever experienced - transportation reps need a remedial class in customer service - follow-up with your customers!!. Secondly, Sam's representatives were not helpful in resolving the problem at all. I finally went into a local Sam's club in our area - the mattress was there- It is NOT worth purchasing - the mattress is so soft until it is ridiculous!!

Does NOT come with Serta's “white glove” delivery

We bought this and have no idea if it's ok. It's still in the packaging in my living room. Buying from Sams Club means a third party delivery service brings it. No setup and carry off of the old mattress is available. It is too heavy for me to move. I'm really unhappy because it is listed as part of the price.

Back Breaker

I wanted to love this firm mattress but I can't. My back hurts so bad that I can't stand up after laying in it overnight. I got rid of my Nectar mattress for this one and I hurt so much more now. I want to cry every morning. Please DO NOT BUY. My back pain is 10x worse and unfortunately I am stuck with it.

Horrible Mattress

I do not make many reviews, but felt the need to do so with this. We have not had this mattress long and it has deep impressions in the mattress where we have laid. We have never had this happen this bad in a mattress before. It has made it so uncomfortable, that we are now on the market for a new mattress.

reply from Serta Team

Hi- we appreciate you reaching out to let us know about the issue with your Castleview mattress. After a few months of use deep impressions would indicate a defective mattress so please reach out to the Sam's Club Serta Team at (385) 256-9674 and they can assist you with a replacement or a full refund if you would rather return. Thanks!

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.

Trash STAY AWAY!

Bought this thing only 5 years ago... and sure enough mattress was too bad to carry on, and having not my receipt could not claim warranty. Been having body pain all the time, and I thought it was just daily tasks and whatever else, till realized it was the mattress!!! 3 years slipping in pain without knowing!!! So because could not make my claim valid for lack of receipt, I decided 4 days ago to purchase a new one! Sure enough nothing good with this Brand! already showing bumpy/deformed signs right in the middle of that thing, that won't even call a mattress! These people are good to sell you marketing only and don't ever mind to produce the quality. STAY AWAY! DO NOT RECOMMEND AT ALL!

Lost firmness within a month

The matress was perfect for a few weeks- I was so happy to get a good night's sleep again. Then it sagged badly after just a few weeks. My husband and I are of average weight. My body is so misaligned while I sleep I wake up with back pain. We have had it for about 8 months, and the only reason we haven't returned it or asked for a warranty replacement yet is because of time/pandemic. Hoping we can still get it replaced. Don't waste your money!

Too firm

We have always bought firm pillowtop mattresses from Sams club for the bedrooms in our house. When we ordered this one, the delivery and set up was great. The first two nights were very uncomfortable. Both my husband and I had sore shoulders and backs. We tried to stick it out for a week, but we knew it was not comfortable for us. I have a bad back and need a firm mattress, but this is very firm! I called Sams club and they were terrific in the return process. The Serta experts helped me pick another mattress set ( the Wynstone II). They took away the Castleview the same day the Wystone II was delivered. I was so happy with the process of returning and ordering a new mattress. We are very happy with the Wynstone II.

not so serta wonderful

I love Serta mattresses. I don't love this mattress. I purchased 2 15 months ago. I'm a big person so when my mates speed returning to a flat surface I figured it was due to my weight with the memory foam. Last night I slept on the set I purchased for my itty bitty Mom and it too has an impression where she sleeps. I will be replacing these mattresses right away as she and I both have back issues that new mattresses were supposed to help. I should have kept our old mattress - hers was 25 years old and mine was 10 years old.. These mattresses were great for a short time - we raved about them so if you are looking for a guest room mates these will work great. If you are looking for an every night mattress - these aren't so Serta wonderful.
