  • 5.0 out of 5 stars Great mattress for memory foam fans
Size: King Style: 14 Inch Blue
Expanded enough to sleep on within 30 minutes. 7 hours later it's at 13-13.5 inches out of 14 inches. Haven't slept on it yet but its really comfy. If you don't like memory foam you'll probably think it's hard. But imo it gives good supporting depth while feeling soft. And the foam rebounds very quick. So far I like it better than my old $1400 hybrid mattress I got at a mattress firm. So for $400-$450 for a 14 inch king, I couldn't be happier. Also, for foam with no additional edge support, if youre laid out you can be very very close to the edge and feel full support. Sitting on the edge is about what you'd expect but as long as my knees are at the top corner it feels like I'm sitting in the middle. As a sceptical buyer, it's a great mattress for the price! Edit after 2 nights of sleep: I work graveyard and am tired most of the time, while still struggling to sleep. I slept great the first time on it, and the second time had 0 issues falling asleep and conked out for longer than I have in months. Great mattress ... show more

  • 5.0 out of 5 stars Well worth the price
Size: King Style: 14 Inch Black
I’ve had another similar mattress from a big box store, wanted to upgrade with my move and this is well worth the price. Mattress did not come with a smell and once out of the package it fluffed up quickly. It does not over heat, equally soft but not too soft where it says or so firm that you need to buy an additional topper. You do not feel weight transfer when using it, as in when someone else gets up or turns. Worth the buy! ... show more

  • 5.0 out of 5 stars Give it a Week
Size: King Style: 12 Inch Blue
The reviews all say this, but it’s honestly true! The first few days I liked the feel but it was definitely a little stiffer than I liked. However, once it really aired out and we started using it, it became so incredibly comfortable. I sleep like a baby all night! Plus delivery methods (since I have a tiny car only!) and the price are just too good. ... show more

  • 4.0 out of 5 stars Very Comfortable, a little firm
Size: Full Style: 10 Inch Blue
I love the mattress but I feel like it's a little to firm for my liking. I'm keeping it as every night I sleep on it it does seem to conform to my body and doesn't feel as firm. As far as cooling? I haven't really noticed as of yet. All in all I am happy with the mattress.

  • 5.0 out of 5 stars Comfy bed!
Size: Queen Style: 10 Inch Blue
This bed is very comfortable for a memory foam mattress. It expanded all the way in just 4 hours. The first night we slept on it our backs hurts which is probably understandable since it was the first time we both slept on a memory foam mattress in awhile. The second night it was so comfy!

  • 4.0 out of 5 stars Time will tell
Size: King Style: 14 Inch Blue
We had a "cool gel" memory foam mattress that I loved. My husband, within three years, complained about lumpiness. We regularly spun the mattress. Time will tell whether this mattress is any better.

  • 4.0 out of 5 stars Great bed for the price
Size: Queen Style: 14 Inch Blue
We bought this bed for our guest room but have been using it for the past 3 wks. I’ve never used a memory foam mattress before so I have nothing to compare it to but I am used to good mattresses. Our previous was a Stearns and Foster so that’s what I’m comparing it to. It is comfortable, absorbs motion so I don’t really notice when my husband rolls over. I will say it seems to run a bit hot but we’re in the PNW so that could come in handy come winter. For the money, you can’t go wrong. ... show more

  • 5.0 out of 5 stars 9/10 would buy again
Size: King Style: 14 Inch Blue
This bed has been fantastic. It is sturdy and comfortable. Between my husband and I we total out to about 550 pounds and that’s before our 40 pound dog. There hasn't been any decompression or stretching so far which is a major plus. My only complaint is if you have a pet the hair will embed itself into the top fabric. So you’ll need to vacuum or something if that bothers you. Aside from that’s it’s fantastic. ... show more
