Wow! I am pleasantly surprised at the initial look at feel of this mattress. For the price and ease of shipping and arrival this mattress is amazing. I ordered the firm 12" King. This arrived with a hefty weight, no damage, it is the correct size and feels firm. I opened it, let it expand for 2 days, the required expansion rate, and slept on it for two night now. I am going from a $2500 Sealy med/firm to this. This mattress is turning out to be everything I hoped for! I was unsure of what to expect before ordering. I searched the reviews and nothing stood out as a red flag. So far, this has been worth the risk to save $thousands$ on a factory mattress from an overpriced dealer! My sleep quality has been amazing for 2 nights now!

This is easily the most comfortable bed I've slept on. I'm only one night into using it, and I slept more soundly than I have in a long time. I have arthritis in much of my body, and this bed changed everything with how I feel when I wake up.

Excellent....but Marvelous with a 2 inch foam topper from Amazon. More comfy than my old $3,000 bed. Also it's extra firm for people with back pain and stiff joints in the morning.

This mattress is worth every penny. It's very comfortable. It's not to hard or to soft.

Definitely a good reason why you try mattress out and they give you 3 months to try it. Aftrr the first month we realized it wasn't as firm as it claimed in the edge of the bed all the way around was very soft did not hold anyone to sit on the edge. We ended up getting a different bed.

Purchased at the end of March 2025 and was perfect for sleeping as extra firm like I wanted now at the beginning of June it’s so soft you can’t sleep on it. We’ve only slept on it maybe a dozen times As it’s in our vacation home.
