  • Excellent sleep !
Style: 14 Inch Size: King
My husband and I researched mattresses forever. We had a very soft worn out mattress and I was worried that this would be too hot. Its not at all. The quality is excellent, it fit our king wood bed frame with foot board perfectly. We bought the 14 inch and our bed is an old antique bed which I should have thought more about the depth lol I am short and 14” is a tad high for me but my 6ft 3 hubby likes it. (I am ordering a step) The sleep is fantastic, the first night I had questions because it was firm. Way firm compared to my old worn out 20 year old mattress but after a few days it’s great. I did put a cooling foam mattress pad protector in it only because I had it and had no place to store it. There is no bounce in this mattress (if ya know, ya know) ☺️😜. I don’t feel hubby get up in the night or the dog jump up at all. This mattress is well Made, seams are great, NO SMELL AT ALL, color is great. Firmness is good not hard but firm. Easy to get out of, the sides don’t sink at all. I don’t know what else to say other than we love it so much we ordered a second for our guest room!! ... show more

  • Amazing product
Style: 14 Inch Size: King
This Mattress is all I could have hoped for. Comfort, is high on my priority list and this mattress is just that! Not to hard and not to soft, but perfect! Perfect value for the money. I am always skeptical at buying things with out seeing them face to face. But I have a new outlook on it now!

  • Very Comfortable
Style: 12 Inch Size: King
It’s medium firmness, not too plush or firm. It’s great for me and my husband. The quality is great. I assumed there would be a bad chemical smell and we would need to open it and leave it for a few days before we could sleep on it but there was no smell whatsoever. It took about 24 hours to fully “inflate” after opening. We purchased the king size and it’s pretty heavy, it took both of us to move it. ... show more

  • Comfortable
Style: 14 Inch Size: King
I was hesitant to purchase a mattress without seeing/feeling it. However, I am so glad I did! I would absolutely recommended this mattress to anyone. It’s is not too soft or too firm. We both are sleeping better and waking up more refreshed.

  • Great height and comfortable topper
Style: 10 Inch Size: Full
To be honest with you, this mattress worth the quality. I'm a person who likes to sleep on firm mattress, but this mattress feom 1 to 10 gets number 7 of being firm, so it's ok for me, but not ideal. It comes in a suctioned bag, so needs to be opened and left for 73l2 hrs to fully extended. Size is standard Full which is for one person. In addition, I like the topper because it's made with smooth materials. ... show more

  • A MUST HAVE/No More Morning Backpains
Style: 14 Inch Size: King
I was skeptical about dropping $600 on a mattress I’ve never even laid on, but once I set it up - Instant relief! Had my first night of sleep in it last night, and haven’t felt this great waking up, in a long time. Incredible value for what you pay and the quality is superb! Highly recommend

  • Very comfortable
Style: 14 Inch Size: King
The box was a little heavy has expected for a King size, so my Husband had to carry for me. It’s fluffy on top and mid firm on the bottom. Very comfy for my 220lbs husband.
