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 amazing. The only downside is, it's very hard to get out of bed now. It actually supports my weight. It's not too firm for my wife. And my biggest plus about this mattress, is it has been helping with my back issues coming from a full foam mattress. The hybrid foam mattresses are far superior

Love this mattress. Be sure to get sheet sets that accept 16” deep to make sure they fit. Comfortable and the extra few inches does make a difference. Purchased this mattress when it was on sale via amazon. It normally was $120+ more but Amazon sold it for $100 less. In essence it cost only $20 more than a less comfortable mattress.

I absolutely love this mattress. It’s exactly as described. Thick & firm but not too firm. It says wait 72 hours but it was done after 24 hours. Only thing I don’t like is the mattress top is ripped a little bit in numerous spots So just be careful I don’t want to return or a refund because I love the mattress itself. AND NOT TO MENTION they gave me a 100$ coupon off the full price of the mattress

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.
