Because it was an Amazon mattress purchase, I wanted to make sure to leave a real review. I bought the firm 10inch mattress due to my size (6’6, 270lb), because sometimes medium firm mattresses aren’t what they say they are. Also, I thought that if it would’ve been too firm, I could get a 2inch mattress topper to soften it, instead of getting the taller mattresses and not be able to adjust to comfort. Also, I was hesitant to by memory foam because I heard hybrids held up better with people of size. Okay to the real stuff! This mattress feels amazing on my back and side. It’s firm but not too firm where it’s uncomfortable. I’m able to feel the relief on my lower back and it’s perfect for my higher platform bed with the built in storage drawers. It’s also sturdy for kids being on it and etc. Doesn’t sink or fall in during intimate moments either (for those who wonder). All in all, this was probably one of the best blind purchases I’ve made and the price makes it more quality. Whenever i have to get another one, this will be the first company I go to look at.

This mattress is comfortable. It (and the box it came in) are heavy but you won't need to move it back out any time soon. We're really enjoying it and are sure you will too!

This bed is extremely uncomfortable and I hate it. I have been using it for just over a year. I was hoping it would just be an adjustment to a new mattress but when my SO hates his side as well. When you adjust the bed up at all the mattress gets a really bad crease and fold in the top making it hard to sleep on. The reviews had me fooled into thinking it was a good mattress but it was a very expensive waste of money.

I'm used to sleeping on a bed that (factually) cost 5 TIMES as much as Sven and Son == so I was skeptical when the reviews and others told me: "the believing is in the sleeping". Darned if they were not right! Sven and Son is the REAL DEAL. It's incredible how soft and luxurious and spine aligning it is. Thanks to all - especially to Sven and Son!

Bought this bed a few months ago and my back has killed me ever since. I can’t stay in it for more than five hrs and I have to go sleep on the couch. Now I’m stuck with an expensive mattress that doesn’t work for me.

**3-year update** ZERO STARS This is a case of love turned to hate. This mattress still has no sinking or body indentations, and I've been pretty lax about turning it when I should. The only bad thing (and it's REALLY REALLY bad), is that there are super itchy fiberglass shards everywhere. I kept finding my floor under my bed covered with a thin layer of sparkly dust, only under closer inspection it's actually short little pin-straight strands of fiberglass that seem thinner than a hair strand. I have never ever removed the gray (zippable) mattress cover. Somehow these shards are eeking out THROUGH the mattress cover. I took off the mattress protector that I had placed it in upon arrival after the first year because it traps so much air that it made the mattress uncomfortable (initially WAS perfectly comfortable without it though). Now I have fiberglass on my floors, in sheets, etc....and good luck getting a picture of this mess. I tried to get a picture with my phone to put here and you couldn't even see it. You can definitely see it with your eyes though. (I may try to borrow an actual camera from someone to see if it will pick up the fiberglass). I expect a mattress this expensive to last at least 10 years. This is a very expensive mattress to have to toss. Fiberglass should never be used as a fire retardant on a mattress. I'm so disappointed, and itchy. I was wondering why I'm so itchy all the time. I thought I was going crazy and had some kind of mental problem. This is a pretty serious health hazard and I urge people not to buy this product. I would like a complete refund to go buy a mattress that doesn't have fiberglass in it. *7-month update* I've had this bed 7 months now, and if anything it's gotten cozier. I do try to turn it every month or so since I'm a single sleeper and I want to try to make it wear evenly, but it's showing no signs of sinking, indentations from my body, or anything like that. I still keep the mattress protector on it, but I unzipped it a little to let trapped air escape (I know it kinda defeats the purpose). The few uncomfortable nights I've had can totally be blamed on my pillow situation and finding just the right setup for my neck/shoulders. My doctor said I sleep like I'm trying to pitch a baseball. :-P The bed is still fantastic, and I still love it. I'm so glad I found this brand on Amazon, and I hope they're still around if I ever need another mattress in the future. *Original review* I ordered this mattress (without the adjustable base) on Friday and it was delivered by UPS the following Friday. I'm happy with the delivery time. I set it up on my platform bed and let it expand for about an hour (it expanded to 13" straight out of the plastic, measured again the next day and it was 14"). Then I sat on it and laid across it. It was heaven. The fabric was beautiful and soft. At first I thought the mattress might be too soft and squishy, but laying on it felt perfect... not too much sinkage (and I'm plus size). I put it in a zippered hypoallergenic mattress protector... and you know how those things trap air? So then you go to sit on the mattress and a huge pocket of air forms? They aren't supposed to change the feel of the mattress, but I slept terribly on this mattress on the first night. I tossed and turned and just could not get comfortable. I woke up with back pain, but after a few nights, my body got comfortable on this mattress (after removing the mattress protector that I put on).
