    • Amazing quality!
Size: King Style: 14inch Firm
We’ve had this about a week now and are in love with this new mattress. It came packaged well, although the shipping carrier had busted open the box, it was wrapped inside and was clean still. Setup was easy and fast. This is a wonderful, firm mattress. I was hesitant to order one online but I couldn’t be happier. ... show more

The mattress arrived well packaged and expanded to full size within a couple hours of opening the box. There was no odor when opened, which is typical of memory foam products. I really like the soft feeling of the mattress. I think it is worth to purchase!

The mattress arrived timely. Perfectly packaged and easy to set up. Medium Firm is highly recommended. No factory smell, and great value for price. Not too heavy. Great quality!

    • Very firm bed!
Size: Queen Style: 14inch Firm
I was looking for a firm bed. This is definitely firm! I'm a plus size individual (275lbs) do I wanted something that wouldn't slouch or indent when I laid on it. This bed gives me support but is very firm!! I love it

    • LIES LIES LIES!!
Size: Queen Style: 14inch Firm
This is a very comfortable mattress, BUT one of the MAIN REASON I purchased this mattress is because the company said that it was good for adjustable beds. This mattress does NOT CONFORM OR BEND with the adjustable bed. Of course I can't return it because I am handicap and do not have the strength to somehow put it back in the box and send it back but also it's stated that once you open the mattress, you CANNOT return it. ... show more

    • Unreal for price
Absolutely love how the bed feels. Good quality and value for money. The performance is there! I'm only giving 4 stars because the bed is not as perfect and square as the picture. Tbh it still looks good and had some baggyness on half of the top but that definitely did not affect the feeling and performance. ... show more
