ok, I will start with the negatives first. On it's own it's a pretty average mattress. I don't think it is the same quality as a hotel mattress, close, but I could tell the difference after sleeping on a Sealy Hotel (which you cannot buy). The Saphire feels like a 5 rating, average, but I wanted something more soft but supportive. The 800 series coil feels dated and a step below individually wrapped coils, imo, they remind me of the bed I had as a kid. I knew this when I bought the mattress, so I will tell you the positives and why I am keeping it. The posturized center third built into the coils make all the difference. After going thru a S&F, Beautyrest, and Latex Bliss beds, none had support in the lumbar area and each killed my back after a few nights sleep. The Saphire has the support but was too firm when sleeping on my side. I needed more softness so I added a 3in memory foam topper ($100) and now it is perfect. The topper gives it a cloud like feeling and the posturized center keeps my back straight. The bounciness is gone and it feels like a more expensive bed. Best of both worlds finally and without breaking the bank. I can finally get a decent night sleep. Maybe you will not have to go this route but this is what works for me. I would say the Saphire has potential and is a good base to build upon. I also got mine on clearance and that is about what I think the mattress is worth. Overall I am happy with it and in the future will replace the topper if needed. Also, you may want the low profile spring since it's quite high if you do add a topper. I think the bed will last a long time especially with the topper taking the abuse and having the ability to flip the mattress. I am a 6' 180lb guy for reference. Hope this helps.

Very comfortable. I sleep on my side as well as on my back. This is one of the best mattresses I have had in over 30 years! I will never buy another mattress from anywhere except us-mattress. They are the best.

I’ve had the mattress for about 3 months and it’s like sleeping on a cloud, while on my back. When I sleep on my sides though it seems like it could be a little too soft. I have hip and sciatica problems though and therefore side sleeping is usually a problem no matter what mattress I’m sleeping on. Also, as with all of the softer mattresses (it seems) you do end up with depressions after a few weeks of sleeping in the same spot. This is a bit frustrating for me since I’m a solo sleeper on a cal king and tend to sleep toward the sides. I switch sides every few weeks, and I have flipped the mattress over, but there’s a hump in the middle of the bed. I’m thinking that this may not have happened with a firmer mattress. Next I’ll try getting rid of the two twin box springs and going to a platform bed frame which may help with this issue.

The mattress is about right for my wife and I. She sleeps on her side and it takes her a little longer to get to sleep, but rests well when she gets to sleep.

It's the best mattress I ever had, so far, about 5 months now.

I was very leery about ordering a mattress based upon reviews and never being able to to actually test the mattress out. However we’ve had the mattress for two weeks now and I have to say I love it. It’s extremely comfortable and supports my back very well. The only draw back and I will learn to deal with it is that when my 220# husband turns over I feel him shake the bed. Thank you US mattress company with timely delivery and a well made product.

We love it! We had no trouble getting used to it! Just the right amount of firm and plush all in one!

Mattress and springs are good. Delivery was not real good though. Was on time but there was no set up as was advertised. Driver helped get it into house and left. Glad I’m not a little old lady who wouldn’t be able to handle it.

Awesome mattress! Just what we wanted!

This mattress is wonderful! It’s softer than I anticipated but not so much that I sink into it and cannot get out of bed. I no longer have shoulder or hip pain when I wake up like I did with my old one-sided mattress.
It’s weird to order a mattress online but the reviews and demo videos help a lot and I am very happy with my choice. I’m thrilled to be able to order an “old-school” double-sided mattress and not have to settle for the one-sided ones they sell in stores.
Worth every penny of it’s very reasonable sales price! Customer service and delivery were awesome!

Definitely would recommend this product and company. Good communication. The mattress is great! I love the fact I can flip it over to prolong the life of it too. My husband and I don’t roll to the middle and it has definitely relieved a lot of my lower back issues. I normally prefer a firmer type mattress but this is actually perfect for our needs.

I went to Vegas in Jan 2019.... stayed at the HRH, and their Mattress was so comfortable..I came home and found one, just a different name !! This is the best Mattress I have ever had !! It is worth every penny spent.

Love our new mattress! The process was easy and the product is great! Sleeping like a baby!

Over the past few years, we have purchased 7 of these mattresses ( twin, queen and king sizes). These mattresses are the best. always a great nights sleep! And double sided allows us to flip and rotate them, extending their useful life. Buy one, or seven... you’ll be glad you did!

Love it!!! So comfortable

I didn't know what to expect buying a bed online, sight unseen, untested. But the customer service (chat) talked me through several options and helped me compare different beds, finding JUST the right bed for me! I am delighted with the comfort and firm-but-not-too-firm mattress.

Would have given 5 stars had the mattress had handles to help in spinning or flipping it. That's why I bought a two sided mattress. It's difficult without handles.

I love my new mattress. I have had it for 2 months now and I could not be happier. It is firm yet soft and I can flip it when ever I want. I no longer get caught in a divot that single sided mattresses all seem to end up with. I am convinced that the reason I got the right mattress for me is because US-Mattress's web site has excellent real information on how each mattress is going to feel and react to my body type.

Excellent service, great product. We would buty again from them.

5 Stars for our King Serta Perfect Sleeper Hotel Sapphire Suite 11 Plush Double Sided Mattress!!! Since the first night on this wonderful mattress, we both have had marvelous sleep. My husband has no aches and pains and actually feels refreshed in the morning, as do I. The Plush is firm enough for good support but not so firm that it is uncomfortable! US-Mattress is excellent and reliable to work with.

Great delivery and mattress. Would recommend this mattress to anyone. From ordering through delivery, all things were excellent.

We ordered a Serta Perfect Sleeper sapphire king mattress. We were kept in the loop as our mattress was being made, which was nice. When ready to ship, the delivery guys called to let us know when to expect them. They arrived as promised and brought the mattress into our bedroom. Love the mattress. We would buy from US Mattress again. Thanks.

Like this mattress so far had it about to 2 weeks. Was looking for a flippable mattress.

I truly recommend the mattress. For the first time in too many years I did not wake up in pain.

Excellent mattress. It was delivered and placed on my bed and my old mattress removed and taken away all in the price. It is sooo comfortable. Love it!!!

Its still too early to comment on the Perfect Sleeper. So far, my 1st 3 nights have been more than satisfying and being a back-sleeper says a lot. Remind me to re-evaluate my experience in another year.

Everything went well. Mattress set is just as I remember it from the hotel stay. Very pleased. Thanks.

Thanks for such prompt delivery!

This is our third Serta Sapphire mattress and boxspring from U.S. Mattress. All three purchases have been seamless, and we are very pleased with the comfortable and well-made mattresses. We will continue to do business with U. S. Mattress.

I have not slept better in years. well worth the money

After enjoying many restful nights at the Marriott and finding out this is the actual bed, we ordered one. We got a 4.5 firmness rating. Delivery was fast, price is great. We have now enjoyed several wonderful nights of great sleep. No back aches, and we both seem to fall asleep faster and deeper. Also wake up refreshed. No night sweats or pains. I also noticed that the big-box mattress stores are also now featuring flippable mattresses, at prices 500 more then we paid for this bed. Go figure.....maybe the consumer is on to something?

We bought two cal king Serta Perfect Sleeper Sapphire mattresses recently for our main house and a vacation place. One pillow top, and one regular. Nice quality mattresses. My wife, who sleeps toward the middle of her side, loves them. I like them ok, but I am an edge sleeper and these have a bit of a crown that tends to roll me off. I'm getting used to it.

We have had our Queen serta perfect sleeper double sided plush mattress for 6 weeks. We absolutely Love this mattress. We hesitated to buy online but could not find a double sided mattress anywhere else. A double sided mattress was a priority. This mattress is perfect for us. The support and comfort was a perfect match. The transaction was seamless. Thank you us mattress.

I tried to get the same mattress as one I had slept on while on vacation that I loved. This was closest match. Not quite as comfortable - maybe because I was more relaxed being on vacation - but real nice

Looking for a new mattress, we picked this one after sleeping on it at the Hilton in Glendale CA. The mattress is very comfortable and the back pain is gone.

still waiting to sleep on it

Only slept on the mattress a few nights but so far it's working out well. Plenty of padding which makes the spouse happy. Medium firm which makes my back happy. Flippable so it lasts longer which makes our wallet happy. And we won't be helping to fill up the landfill with non-flippable mattresses that wear out in only a few years which may make the Earth a bit happier. Delivery was quick. The delivery people were quick, helpful, and professional. No damage or other issues. Great experience.

I was so worried about ordering a mattress online. I read reviews and was so glad that I made the decision to order. Ordering was easy, delivery was great, and the mattress is WONDERFUL!!

My wife researched buying a new mattress, since our old one was sagging in the middle and was non-flippable. It is hard to find flippable mattresses in the local stores. She found US-Mattress had the best product selection and great prices. We ordered a flippable mattress and box spring. The process was quick and efficient. The mattresses were delivered on time. The delivery company made sure everything was setup correctly. I would order from US-Mattress again.

I was looking for the same bed as used in the Hampton hotels. Joshua T suggested the Serta Perfect Sleeper Sapphire Suite. Same mattress, but about $400.00 less than the price offered on the Hampton website even with a $600.00 off promotion. The entire shopping experience could not have been easier. I was kept up to date on my order's progress and delivery went smoothly - on time and very courteous. Love the mattress and will definitely recommend US Mattress to my family & friends.

Years ago I had a flippable Serta Perfect Sleeper that I loved. When I tried to buy another one, I was told that double-sided nattresses were not being made anymore. I have spent a fortune on expensive mattresses in the past six years, and they were all junk. I finally stumbled upon US Mattress and the Serta Sapphire Suite. I took delivery this week, so I will reserve judgment on the mattress for a few weeks, but I really think it will be wonderful.

My husband and I had slept on an old-style (hot) memory foam mattress for years, then had a wonderful stay in a Hilton that used this mattress. It was the best night we had had in years. When we finished our remodeling and decided to upgrade to a king-sized bed, US Mattress was the only site I could find that carries this line. What a relief to be rid of the sweaty slab of foam! This mattress is firm without being hard, and has just the right amount of cushion.

I did fast delivery and the bed was delivered in less than a week to my door. The truck driver helped us bring the boxes into the house. The bed is comfortable and not as firm as our old mattress, an expensive Sterns and Foster which began to sag after only 3 years. The padding on top of the mattress is just enough. It is a bit higher than our old mattress and I got the regular box spring. I would suggest the low profile box spring. I love that it is able to be flipped.

We were tired of fighting the lumps from our "pillow top" mattress. We called several area mattress stores and were told the double-sided plush mattresses are no longer being made. We did online research and found this mattress from U.S. Mattress. It was delivered almost 10 days before the quoted date, the men who delivered it took our old mattress and put our new one in place in a matter of minutes. We have been sleeping quite well ever since!! Highly recommend it!!

Bed is a bit rounded on edge, still breaking in but seems to be getting better. Seemed firm when we got it, so was unsure if it would be to hard. So far it is sleeping perfectly and conforms to the body. I am very heavy, husband not so bad but around 200lbs for him, so wanted something sturdy. This replaced a 16 year old Simmons Cali King Plush, which was awesome when new but very worn out now. So far so good, I have bad hips and neck and need support, but nothing to firm and this works.

Delivery guys were super! Mattress is firm, supportive with a soft top. Just as described in sales video. We are going to order another one!

I expected a firm comfortable sleep as to help back tiredness but not the case...too soft and not a lot of comfort at all. You really need to touch and feel before you buy.

We have had our mattress for over two weeks now and we are very happy with it. I was set on getting a double sided mattress and really had a hard time finding one. This mattress is even more comfortable than I had expected. The delivery service was exceptional. US-Mattress.com will be the first place I look for future mattresses.

Could not be happier. You will not go wrong with this mattress nor US-Mattress. The price and quality cannot be beat. If you are old enough to have bought and used mattresses before they began making the pillow-top type, you are in for a pleasant surprise. This mattress will give you a good sleep for years to come because you can "turn it over"!

We had slept on this mattress at Comfort Inn & Suites several times and were thrilled to see that we could obtain one for our home. It is exactly as described. Since we have only had it two nights, I withhold a final say on durability, but it is firm and comfortable. I have back problems and am pleased with how I feel in the morning after sleeping on this mattress. It took us almost 4 weeks to get the mattress, but I was updated several times by email as to the progress of the order.
