My wife and I bought this bed to replace an old spring mattress that we had. We thought it would be a good idea to have an open mind and test out some other products on the market besides springs. We went to the stores first to see what exactly it was that we were seeing online. The cheapest memory foam mattress that we found were around the $900 mark. We looked at Sleep Number beds, which did feel nice, but not for $1500 to $2500. Anyhoo, we found the Sleep Innovations 8" foam in the $300 dollar range and it was a no brainer. I know its a little nerve racking dropping that kind of money on a mattress you haven't seen before but it was worth every penny! I read all the reviews and prepared myself for the worst case senario. I expected a queen size mattress in a small box that was gonna stink up the house with a chemical odor that wasn't comfortable. That wasn't the case! The mattress did come in a small box, it was about 2' X 2' X 3' and it weighed about 70 lbs. Shipping was free :) I cut it open expecting the odor, and there was. The odor lasted for a whole entire 10 minutes after the mattress expanded itself accross the bed. As a matter of fact we slept on it that night and we were pretty comfortable. However when I woke up in the morning I felt like I had been hit by a truck my wife wasn't much better. This went on for a little over a week but the soreness did stop. I think our bodies were adjusting from the springs to the foam would be my best guess. Anyhoo, the moral of the story is that we have had it for about 3 months now and I couldn't imagine not having it and I kick myself for not buying this product sooner. If anyone asked I would defineitly recommend this mattress despite the intitial fears of buying something you can't really see up close. Also as for the bang for the buck, you can't screw up unless you absolutely hate it.

I've been searching for a mattress good for lower back problems. What appears to be the best type of mattress has a soft top layer of 2-3 inches and a very firm lower support layer.

I have tried several mattresses through Walmart and Amazon. None worked well. Some had a soft middle layer which is very bad for a sensitive back. Some were simply too soft. I need a supportive mattress. Several of the Walmart mattresses were over a year old and would not inflate properly.

Eventually I broke down and spend $1400 on a Tempurpedic Cloud mattress. It felt good initially. Very firm. However as winter approached and the house became cooler, the mattress turned to concrete. Too hard even for me. But that in itself wasn't the problem. The problem is that Tempurpedic's memory foam is too heat sensitive. The mattress would initially be hard as a rock, but would soften. The cloud is an 8" mattress with 4" memory foam, an inch of soft eggcrate, and 3 inches of firm support foam. Sitting on the cold mattress shows the problem. At first you sit on the rock hard mattress but then slowly start sinking. The sinking doesn't stop until several minutes later when you pretty much made it through the memory foam and egg crate. You may have sunk 4-5 inches into this mattress. Way too much.

A mattress which sags in the middle is the worst for a bad back, especially if you sleep on your stomach. The Temperpedic ends up doing this. A person's middle is heavy and gets hot under a blanket and slowly sinks all night. Feet and head are lighter and more insulated from the mattress (pillow etc). The end result is that your middle sinks way down, but feet and head dont. It acts like a sagging mattress. Add in partners movements and it makes for an unpredictably soft saggy mattress.

Edit: one year later, I'll bump this to 3-stars. The mattress did soften over the first two months of use, however this stabilized. It is a little softer than I would like, but the foam seems to have settled in at its natural state of resilience and isn't degrading further.

Original review:
I've had this mattress for 6 weeks now. I was initially very happy, but the foam has broken down and deformed. After 2 weeks it was already losing its "resiliency" - e.g. not bouncing back into its shape. There is a clear indentation or "valley" where I sleep, with a "ridge" between my side of the bed and my wife's. The "ridge" exists because neither of us sleep in the middle of the bed. I worry that after another 6 weeks the bed is going to be a "w", like two hammocks joined together. For the record, I weigh 175 lbs - if this bed can't hold up to the average size guy, then the foam material they use is cheap.

This is my 2nd Sleep Innovations mattress. Bought mainly for my kids. I own the queens size for 2 years.

This is a great price because IKEA charge $400 for a similar memory foam mattress, don't be fooled by the $270 "foam" mattress, memory foam is the difference. You are paying for the soft foam that forms to your body's impression. IKEA does not have a decent memory foam mattress with 7" of foam for less than $400.

It's great for people who are side sleepers, no more aching shoulders backs.

I do caution that if this is your 1st time with a memory foam mattress, your 1st night actually takes getting used to. The 1st difference is your lower back gets proper support and you actually feel something is there in your lower back. Now some people with no back problems may actually feel uncomfortable, like sleeping with a pillow behind your back feeling.

Rest assured that you will get used to it and start loving the back support.

This is a great price for a mattress because it beats the low end models, this uses a decent thickness of memory foam. Those expensive ones with a thicker memory foam may seem great but it is not good for people weighing over 180 pounds you just end up sinking more.
