It seems to be a common theme that those of us that need a new mattress, but at an affordable price, do a ton of research. I searched for weeks online for different mattresses at different stores and tried to see who was having specials (I tried to know which one I wanted by Amazon Prime week, but I just wasn't ready to decide by then!). I looked at beds that had thousands of reviews because I thought those would be most reliable due to the quantity of those that had tried the bed. I looked at beds that didn't have a ton of reviews (like this one with I think like 400-700 hundred, I can't remember), and I also did Google searches to find more thorough reviews from professionals. My goal was to buy a king size mattress for $250-$300. I was really close to picking the Amazon Basics (or something like that) and I can't remember exactly what pushed me to this bed, but I think this one was actually a bit less expensive for the 12in size vs the 10 inch and from my research I did gather that the general consensus was to get as many inches as possible (that's what she said) because a memory foam bed probably wouldn’t expand as largely as it should. So the Vibe bed it was!I ordered on a Thursday and it was supposed to arrive on Saturday (the day my new bed was to arrive), but lo and behold I had it by Friday night! As you see the box came it a very good condition (something I think some have complained about). So I am a single woman and had to get it up to my bedroom on the second floor. I will say it took a bit of elbow grease, but I managed to walk it into the house and then slide the box upstairs and into my room. DEFINITELY do not remove the bed from the box until you are ready to open it.Once upstairs, I laid some blankets down and then pulled the box off (while leaving the plastic on). I unrolled the mattress and it expanded to about 8 inches in less than 20 minutes and 10 in less than 20. I couldn't resist trying it out, so I cut the plastic a little bit and crawled in (seems weird, but with two kids I did not want that plastic off until the mattress was going to be immediately covered with a mattress protector and sheet!). It was decently comfy!Like it wasn't super firm by any means, but my ideal bed is one that literally feels like a super soft pillow, so I did notice a difference there, but it was 95% fine. Like I know a topper would take this bed to 110% amazing so I am good with that.Two days later (I didn't really check the next day) and the bed was fully at it's 12 inches. I was VERY impressed, because the pics in some review of memory foam beds made it look like the edges of the mattress never really took on a rounded square shape. Not this one! This bed fully looks like a completely even, regular mattress.And I have been super tired lately so that could contribute, but honestly I have never slept better on a bed! I set an alarm to wake me up halfway though the night so I can see that I have more time to sleep, and with this bed I always miss that alarm!I snuggle up in this bed with my nice warm comforter and that is all she wrote!I have no comment about whether the mattress gets hot, because with comforters I would have no idea how someone is able to attribute being hot to the mattress and not, um the covers?Overall the only thing that could make this bed better is if it was just a smidgen softer, but truly for the price I would definitely pick this bed again.Some memory foam users complain that the sides begin to sag eventually so I am praying I don't encounter that. Overall, I know this review is rather lengthy, but I wanted to give a review that would have empowered me to take the plunge when I was shopping. Hope this helps!8/5/20 Update:As a single person I sleep on one side of the bed and I will admit this side is lower. Still would buy this mattress!
