  • Great Mattress
Size: 12 Inch King
Love it , great size , soft. This mattress is very comfortable and supportive. I’ve been sleeping much better since I got it. It has the perfect balance of softness and firmness. Great quality for the price. I definitely recommend it!

  • Super comfortable mattress!
Size: 14 Inch California King
This mattress is a beast weight wise. My husband got a workout dragging it upstairs! It opened up with ease and didn't have significant off-gassing. I feel the corners of the "topper" didn't fully expand (but it mostly expanded), however, it doesn't affect use and once the bedsheets are on and comforter on, it's not noticeable. This is replacing a 6-year-old Sealy that was a $3k queen and I actually sleep better on this and rarely wake up in the middle of the night anymore to switch positions. I bought this as a surprise for my 6'3" husband that always had his feet hanging off the bottom of our queen bed. I will say, it's definitely on the firmer side of "medium firm", but very comfortable and supportive. I'm a side sleeper, so I am considering an additional 2-inch topper, but not positive it's needed. The foam doesn't retain body heat to make either one of us too hot or sweaty. One thing I love is that it's SILENT when you get in and out since I usually go to bed much later than my husband. I was worried about buying a mattress without laying on it first, but I'm happy with this purchase and would recommend to others in a heartbeat. Also, for this price, I am considering it in queen-size to put in our second guest room (as the Sealy is in the other one). I really think it's a great purchase for the price and comfort. ... show more

  • Great Bed.
This bed is about the best bed in a box i have ever bought. It's super comfy and has lots of space for a king sized bed. It has definitely helped with my bad back pain. The pillow topper i wish was a little more firm. you tend to slide off if you get to close to the edge. Good bed throughout though!! ... show more

  • Americas Next Top Mattress
Size: 12 Inch King
I bought this mattress because the very first Americas Next Top Model, Adrianne Curry, bought one and posted about it on X. She was replacing her $5000 mattress. So I thought, this girl knows something I don’t. Turns out she does. This mattress is great. So comfortable. Excellent price. Soft, but not too soft; firm, but not too firm. Only time will tell if it lasts, but the price cannot be beat. I was worried 12” would seem short, but it doesn’t at all. ... show more

  • Most amazing bed we’ve ever owned
Purchased this king bed with frame several months ago and wanted to wait to rate. This is the most comfortable bed we have ever owned. A bit high so if short might need a stool like me but worth it. The movement isolation is great and we get a great nights sleep. We purchased the slim board to go between frame and mattress too. Amazing bed. ... show more

  • Awkard AF
Size: 14 Inch California King
I wanted to give myself a few months to sleep on it and provide a fair and thorough review. Well, it is not the greatest mattress. It is soft on the edges and hard in the middle, which is very uncomfortable and odd. I don't recommend it if you're short because it sits high, and the sides being so soft make you slide off when you try to sit, or if you're too heavy. My husband weighs more because he is very tall, and he hates the mattress. ... show more
