Live & Sleep Classic 10 Inch Full/Double Bed in a Box - Medium Plush Firmness Memory Foam Mattress, CertiPUR-US Certified for Safe Sleep | Perfect for Guest Rooms, Dorms & Small Apartments

These mattresses were to replace our memory foam ones that came with our adjustable bed several years ago. These are comfortable and I like the firmness of them. We have only had them about 3 weeks, but so am very pleased.Update: 8-26-18: It is now almost 9 months since we purchased this mattress, set it up and have been sleeping on it. I am downgrading it again to 3 stars because I am afraid we might be replacing the mattress before one year is up. It is really soft now and I find that the mattress is now sagging on both sides of the bed and causing back discomfort for both my husband and I. I expected more from this mattress and am disappointed that it is not holding up as I thought it might. And we continue to rotate it. I understand that there is a 20 year warranty, but unfortunately, the cost to return this mattress is on the buyer and I suspect it will cost just as much to return it as what we paid for it, just under $500. So my designation went from Happy Sleeper to Disappointed Sleeper. And yes, the mattress is a budget mattress so I will keep this in mind on our next mattress purchase.Update: 7-20-18: So we have had the mattress now for almost 8 months. The verdict: The mattress is not quite holding up as I would have hoped. I wish I would have purchased a "very firm" because the mattress is getting softer over time and I do not know if this is expected from these foam mattresses or not. I like a medium to firm mattress but I am afraid in several more months, it is going to be too soft and start to bother my back. My husband weighs over 200 lbs and I am afraid his side of the mattress is holding up less than my side; I weigh in at 120 lbs. And oh, I have been rotating our King size mattress on a regular basis, at least every 4 weeks and sometimes that is just a 90 degree turn instead of the 180. But the 90 degree works even though the mattress hangs over a little on each side of the bed when placed this way. Next turn is 90 degrees again and puts the bottom part of the mattress at the head and vice versa.I will still stand by my initial review but wanted to post an update now that we have slept on it for close to 7 months. But I have gone from 5 star to 4.So far this mattress has met my expectations. This is the first time my husband and I have purchased a memory foam mattress so I was a little apprehensive before buying it and worried that we might not like it or get a restful nights sleep. As it turns out, I am pleasantly surprised after 3 nights of sleeping on it. I did do a lot of research and read many reviews on different memory foam mattresses before making a decision to buy this mattress. Further, it got a little overwhelming at times because it is somewhat subjective as far as what someone finds to be a soft versus firm, etc. For me, I sleep better with a firm mattress and as for this mattress, I am finding this to be a medium firm, perhaps a 7 out of 10 with 10 being the firmest. I am also a side sleeper as well as a back sleeper so I was worried that a mattress too firm would not be ideal for my side sleeping. So far this mattress has worked for me and my husband who is also a side and back sleeper.I was also a little leery about purchasing this particular mattress, the Resort Classic 12 inch King size Cooling Medium Firm Memory foam mattress because there were no reviews. However, Live and Sleep had sold many of the 10 inch mattresses, also the Resort Classic, so I took a chance with the 12 inch and I am glad that I did. Overall I am happy with the purchase especially after doing so much research which gets confusing after a while. If you are a side sleeper or back sleeper, this mattress might work for you providing you like a medium firm mattress. And as far as smell, there was little of that, if any. As far as heat, so far there has been no issue with this mattress sleeping hot.Lastly, this mattress has a 20 year warranty although the warranty information did not come with the mattress when it was shipped. However, I quickly contacted Live & Sleep and they promptly sent me a copy which basically covers any defects found in the product. Of note, the purchaser is responsible for returning the mattress.Overall, I am a happy sleeper! And especially since the cost of this mattress is so reasonable compared to the last innerspring mattress we purchased which lasted 1 whole year before we could not tolerate the sagging any longer.Arrived on time. The box was damaged, but that didn't affect the product. Note that the box is very heavy as advertised and as some others have mentioned, but my husband was able to bring it up the stairs to our guest bedroom. It expanded to its full size which was cool to watch. Note that there are still a few, "wrinkles" on the side where it looked like it was supposed to expand more and become fuller. I slept on it the first night as I wanted to 'test' it before I had 4th of July guests, and I was fine with it. I am a person that can sleep almost anywhere, even on a couch, and be fine. Note that I am very small and weigh about 100 pounds. For me, I could sleep on this every night - nothing great, nothing bad. Next, my out of town guests visited for 3 nights. They are of average size and marathon runners and liked it, but the mattress kept falling thru the slats of the bed so we heard a 'crash' as part of the bed poked and then fell thru the slats onto the floor beneath the bed...and yes, the bed had all the right number of slats for its platform. 2nd night, we added more slats..by husband and his brother actually got out a saw and cut more 1 by 4 slats to give the bed extra platform. It wasn't enough and the 3rd night, we heard the crash in the night again. My guests just took the mattress off the slats and laid it next to the bed on the floor and that was fine for the last night of their visit. My husband slept on it the 5th night to test it. He didn't care for it. He felt is was difficult to get up and out of the mattress as it squished down/sinks where you laid. My husband is 5'8" and 175 pounds and felt it was like getting out of quick sand. This week, I finally went out and bought box springs for it so it wouldn't poke thru or fall thru anymore. With the price of this mattress NOT being a real bargain (I paid more due to many positive reviews) at $339 for the queen size and now I had to spend an extra $125 on box springs for a total of about $500, I paid as much as if I had just gone to a middle of the road store and gotten a basic set of traditional mattresses. If this mattress was half its price, it would be ok and despite the issues, I could have rated this higher, but I always look at value - price you pay for what you get, and I just think this mattress is a temporary solution that appeals to a limited number of people. A 'junk mattress' of sort you can have as a backup for guests for a few nights. Beware of the surface its going on too. That's just our experience after 10 days. I'm glad others on here seem to love theirs, but I'm dissapointed.
