  • Good shipping, comfortable, and holds it shape
Size: Medium Firm Queen Style: 14 Inch
This was packaged very well and even included a tool to make opening it easier without damaging the mattress. It was really heavy, but it doesn’t sag or sink so it must be for good reason. It holding it’s shape keeps it comfortable. This mattress is on the firmer side, but I personally like that, if you prefer a softer mattress get a pillow topper or a different mattress. The manufacturing of the mattress is of a higher quality, the seams are sturdy, stitched well, and stay in place. The pillow topper filling doesn’t shift around so it is an even feel through out. You can sit on the edge of the mattress and it stays put with very little give and bounces right back in place. ... show more

  • The Feel of the Mattress Was Great
Size: Medium Firm Queen Style: 14 Inch
I purchased this mattress for my guest bedroom based on the reviews. I have to agree. This mattress is awesome. I purchased the 14" mattress. With just one day, it has inflated to 13". So, I am going to give it another day. However, when I laid down on the mattress it supported my back and my side. It was very easy to set up. And a cutter was placed in the box to unwrap the mattress. The mattress looks great. It has the right firmness for anyone dealing with certain issues with back or neck pain. I am going to order another one for my bed. ... show more

  • Not even semi firm,but comfortable
Size: Medium Firm Queen Style: 12 Inch
Great bed, very comfortable for price. However if you are needing a bed a little on the firm side this is not a good choice, it's got zero firmness! Its still very comfortable but you do just kind of sink in. Im a little worried that in time its gonna be an issue as far as being able to feel the springs. But for the price you cant expect something to last forever. ... show more

  • Amazing!
Size: Twin Style: 10 Inch
This matters is literally incredible! It is a hybrid mattress and is soft when you are sitting, but very firm when you are lying down. True to size and fluffs up in just a few seconds. I have a break in my spine and need a lot of support. I was skeptical of the price, but am not disappointed at all. I have been sleeping on this mattress for 2 months now and it is still as comfortable as day 1. ... show more

  • Great value for the price.
Size: Medium Firm Queen Style: 14 Inch
Why did you pick this product vs others?: what I can say so far is that the bed is very durable so it will last me longer than my bed I had with my weight. For the price it’s not bad. It’s a good choice if you’re looking for a medium firm without the memory foam or softness that won’t last you long if you are heavier in weight. Can’t wait to try it out and see if I get that good sleep I need. ... show more

  • Very comfortable mattress
Size: Medium Firm King Style: 14 Inch
“This mattress is really nice—firm at first, which took a little getting used to, but it softens up beautifully over time. It just needs a bit of patience to fully fluff up and reach its perfect comfort level. Since switching to this mattress, I’ve had the best sleep I’ve experienced in ages. It strikes a great balance now that it’s settled in, and I’m thrilled with how supportive and cozy it’s become. Definitely a solid choice!” ... show more

  • You get what you pay for
Size: King Style: 12 Inch
For the price it’s a good mattress, at the end of the day you get what you pay for. I’ve had mine almost 6 months and it’s already kinda rough. The top is uneven and rolls up in some areas, I can feel the springs poking me in different spots and it makes a lot of noise when you move around. Overall not uncomfortable but NOT meant to last. Customer service also appears nonexistent but this website sure makes that difficult either way. ... show more
