I have bought this mattress several times and loved them. They are comfortable and for an air mattress had a long life. This time 10 days after the return window so I can't just send it back it keeps going flat. Sometimes the never flat pump works and sometimes it quits but when it does work it runs all the time so I think it might be over heating? I cannot find any holes, rips or even feel where the air is leaking. I think it might just be slowly leaking from seems. The first few times we used it, it was great just like all the others but a month later when aired up it leaks slowly overnight so it is uncomfortable by morning after the never flat pump quits working. Have been trying to get a hold of Serta because it is supposed to have a 2 yr warranty but so far no luck. I read on their page that they only honor that warranty if it is bought through Serta. Com so I am not sure they will honor it and the 30 days for Amazonis over Serta has gone down hill and I am so disappointed unless they honor the warranty.Update: this is manufactured through Exxel and they said they are going to help so yeah this might have a great ending and I will change to 5 stars if it does because I did love these mattresses

No sé si esta unidad venia dañada, pero se desinfla completamente si no esta conectado para que la bomba secundaria. Yo adquirí un colchón exactamente igual pero queen size, en 2016, de la marca Instabed, el cual lo podias dejar desconectado una vez inflado y se mantenia firme. Aun asi, la bomba secundaria del Instabed ni la oias cuando funcionabas.En cambio, este lo inflas y a los pocos minutos la bomba secundaria empieza a trabajar lo cual indica que se está escapando el aire además que es muy ruidosa y para los que tienen sueño ligero va a ser muy molesto.Este serta lo dejé desconectado por un dia y se desinfló al 100% por completo.Tenia mas expectativas de este colchón siendo que es el mismo diseño del instabed.

I cannot say enough good things about this air mattress. I have gone through 3 active era mattress’ which constantly deflate or the seams rupture.This air mattress ive been using for a few weeks and havent even had to re-inflate it once, it didnt stretch and has kept all the air inside. It’s incredibly sturdy and what id expect from any air mattress, but unfortunately many other manufacturers cant get it right. Dont even waste your time with other ones and just buy this, you will waste so much money on other crap.This is the #1 air mattress ive ever had, hands down, no contest, 100%Update after 6 months of use:Still the absolute best air mattress ever made, absolutely no issues in 6 months of use every single day and even taken it camping multiple times deflated, reinflated. Everything is absolutely premium with this product. Legit dont waste your money on any other brand, this thing is great!

The adjustable firmness is just about perfect for handling spinal problems. The queen size is good for two. Is there a king size available or in the works? Highly recommended! Appears good for long term use with the "never flat" operation.

If you are looking for a air mattress this is it! Bought this for a guest to sleep on for over 2 months. NEVER deflated. No problems, easy setup and easy to deflate and move around or vacuum if you want too. It's actually VERY comfortable to sleep on, I tried it out myself and my guests loved it. You do need a good sheet on it like I would recommend flannel as it does get a bit cold, but had no problems. Guest loved it said it was better than there own bed at home. The pump isn't too noisy at all - I noticed it only came on when you got out of bed, didn't seem to come on during the night at all. You can tell this is very good quality. As far as the size its a great height because honestly it just feels like a bed. 100% recommend.

I was excited when I unboxed it. It looked AND felt like a quality item. I slept on it a few times to try it out, it was comfortable enough for at least one person. With two short people of average weight (less than 300 lbs combined) it was a getting a little uncomfortable since you have to sleep in the center of the mattress or risk sliding off. All of this would have earned it at least 3.5 stars. Sadly the mattress started to leak at one of the seams, just we had family. It is past its one month return period, I have not choice but to repair it myself. With this mattress being a well known brand and with the price I paid, I would have expected better quality or at least a better warranty period.Update: I repaired the small whole with a bit o silicone and used the matress for a month and a half before ot developed a second leak around the main pump. I managed to partially repair it but after 30 seconds I can here the 'Never Flat' pump come on and stay on, meaning there is a slow leak some place. I have gotten about 2 months of use in 2 years our of this thing. Save your money buy something else. See pics of my repairsàà

I have had a few air mattresses...because of my work...I use them frequently and on a daily basis...this mattress is by far one of the best i've ever had....last year my favorite one I had for years which was a aero bed...finally bit the dust...I had purchased a sound sleep mattress from amazon and within a few months...it sprung leak...that I could not find...also developed some weird bubble...I did call the manufacturer and with no problem they sent me a new bed....I really appreciated the man who I spoke with and how he made my life easier by just sending a new bed out next day...but unfortunately...the second one lasted even less ...this time I found the leak...it was at the seams on the top where the "quilts" where its almost impossible to patch because the top is fuzzy...we watched a you tube video and sanded it and the whole 9 yards but the next day it sprung another leak on another seam...ugh...I wanted to like the bed because the guy at the place was so nice but truth be told...you always had to add air to it and they just were not built to last....so that brought me to this bed...I had used one once before for a few days and really liked it...and the price here on amazon was way cheaper than at Target for $200 so I decided to give it a try...now...they do offer a pillow top option for a little more money...which I thought was a good idea because I think that would help prevent leaks and add some comfortability to the product...but I wasn't impressed with the reviews on the pillow top...so I just decided to buy a pillow top on my own from amazon with better reviews...and I ended up with the Hospitology Heavenly Microfiber Goose Down Alternative Overstuffed Mattress Pad/Topper, 60-Inch by 80-Inch, Queen....it fits perfect and I love it...goes on easy...just adds a little added comfort...its not huge...don't get your hopes set on it being like a mattress...keep it in perspective and you will be fine...its just a quilted fitted sheet...which I feel help protects the mattress plus gives you more comfort then you would have with out it....definitely worth it in my opinion....Now for the mattress itself..its a nice height...I believe the highest you can get in a regular air mattress 18"....it has an automatic pump...so you just plug it in and set the dial to the firmness you want...plush...medium...or firm...and let it go...it shuts off when its done...an awesome feature...since my other bed would just keep going...as do others and I think you can damage it if you over inflate a bed...so this is a great feature to have...its the same when you deflate it....which again....if you ever had a bed you have to shut off manually when deflating it...i have had mine overheat and shut off in a bad way...tho they still work after it rests a while.I personally like my bed firm...and it is firm...it feels great...you don't sink into the bed and wake up with a sore back...its FIRM...and thats just awesome...Now...this bed comes with a feature....(NEVER FLAT) that will refill air if any is lost...i'm just gonna tell you now...I think thats a hit or miss...I don't think mine works...not exactly sure how much air has to be lost for that to kick in...but I was able to hit the firm button manually and it was missing some air so clearly the feature never activated...to me...this is really a non issue...one...you have to keep it plugged in for that to work...and I don't really want to do that...and second....this bed really doesn't lose air like others....when you first inflate it...you may need to add air the first 2 days while it adjusts to being inflated the first time from being in a ball its whole life...but after that...it just a non issue....no matter if one or two people sleep on the bed...it maintains its air....my other bed lost some air pretty much every time you used it especially when 2 ppl slept on it...again...I have had NO issues with that and this bed....overall...its just an amazing bed especially for people who need to use an air mattress long term...I can't even express how happy and impressed I am with it...and like I said...I have had experience with air mattresses for a few years now....and its just a great bed for an air mattress...the only thing that could make it better is if it had a head rest like my aero bed had...because thats a great feature...but you can't win them all...at least you get a good nights sleep without waking up in pain from sinking...I did contact amazon about the NEVER FLAT feature not working and they were awesome in refunding me a small portion as a resolution instead of returning it and trying again...which I felt was a great compromise..since that feature was a non issue to me ...but it was an advertised feature so I felt they should be held to a standard....last purchase I made for this bed was a fitted sheet to go over the fitted pillow top sheet to keep the pillow top clean....this is the one I bought....Utopia Bedding Fitted Sheet, Wrinkle, Fade & Stain Resistant, Hypoallergenic, Includes one Fitted Sheet (Queen, Black)it fit great...nice an deep....I hope this review helps someone in making a decision...

UPDATE, 1 year later:Changed this from 4 stars to 5. Slept on this bed EVERY NIGHT since it arrived a year ago. Perfectly comfortable. My troublesome back issues have been effectively held at bay...apparently my back was as happy with this bed as I was. Never Flat pump worked perfectly and was super quiet. Rarely EVER came on...UNTIL I recently accidentally knocked my cat off the bed one night. In her scramble to avoid the fall, she must've punctured it somewhere, though I could never find it. The Never Flat pump came on more and more often, until it got to the point it was on ALL THE TIME. Then it became too loud to allow for sleep. I lovingly laid it to rest at the recycle center last week and replaced it with a 'real' bed...a Signature Sleep Contour 8" twin mattress paired with a Pragma Bed Simple Base Bi-Fold twin frame.If not for the cat, there's no telling how long I'd have continued my relationship with this 'temporary' bed. Should I ever have need of a temporary bed (in a bedroom where the cat isn't allowed), I will definitely order another. Cannot say enough good things about this bed.Some reviewers complained of it being cold in winter. I had no issues with this (and I get cold VERY easily), perhaps because of the thick memory foam topper and flannel sheets I used during winter.Here's my original review:Been sleeping on this every night for around a month now...really loving it! Keep mine set to Firm. Adding a Serta memory foam topper allowed me to keep the support the doctor ordered, while being able to enjoy some cozy plushness as well. Deep ruffled skirt hides the fact that it's an air bed and the topper on top of it keeps the skirt and sheets from sliding around. Tossed a comforter and some pillows on it and it looks like a regular twin bed!First week I had it, I heard the Never Flat Pump come on fairly regularly...usually when I got off the bed in the morning. NEVER heard it at night...it's absurdly QUIET. Second week, I never heard it come on at all, so was beginning to think it was a dud. Before returning, I tested it by deflating it a bit, but leaving the setting on Firm. Sure enough, the Never Flat Pump kicked on, just like it was supposed to! I guess the fact that I never hear it come on is an indication it's NOT losing air!Only thing I DON'T like about it so far is that it's design does not work with standard twin fitted sheets...it's quite hard (and expensive) to find fitted twin sheets with the 18-20" pockets, and if you use one, you need to do some alteration around the air intake for the automatic pump so that airflow is not interrupted. Either that, or disable the automatic pump altogether after the first week, since it so rarely needs to come on anyway!Not sure how it would work for a larger/heavier person. I'm 5'2" and 118 lbs and it doesn't scoot around when I get on and off it. I have it sitting on a wood floor and it doesn't move unless I purposefully move it. Nice thing is that when I open and close the window it's in front of, or when I remake the bed in the mornings, it's easy to move over when I NEED to move it, since it's just air, and not a heavy wood framed bed!How it holds up as a primary bed is yet to be determined, but so far, I'm getting the best sleep I've had in YEARS! I used to wake up several times a night...I thought that was just normal. Once I fall out on this thing at night...I'm OUT til the alarm goes off in the morning, and I don't want to get up then...it's too comfy!
