Style: 16 Inch Size: King
I don't leave reviews often but this bed is worth the time!! It inflated super quick and it's a great quality. I wasn't expecting it to be so soft and comfortable but it's amazing!! Great bang for your buck! Highly recommend it!

  • Incredibly Comfortable and Supportive
I couldn’t be happier with the LETMOON Queen Mattress! From the first night, I noticed a huge difference in how well I slept. The 12-inch gel memory foam provides the perfect balance of softness and support — it molds to my body without feeling too sinky. It also sleeps nice and cool, which was important to me since I tend to overheat at night. The mattress expanded fully within a day and had no strong odor. For the quality and comfort you get, it’s an amazing value. Highly recommend to anyone looking for a great night’s sleep! ... show more

  • You get what you pay for!
Style: 14 Inch Size: California King
Personally this bed is too firm for me and my wife. I am primarily a side sleeper. My wife sleeps on her back and side. We wake up with our hips hurting the next morning. I purchased the higher grades bed because it said it was corner on the edges. I works beg to differ. I weigh 215 pounds and the edge sinks more then I anticipated. The springs constantly creak when shutting on the edge putting my socks on the morning. I went from a gel mattress back to the standard spring bed because of the price point. This mattress is way lighter than the gel mattress I had. I never thought about the weight difference being an issue when I purchased the standard spring mattress. Another problem that occurred when I put my socks on in the morning is the whole mattress slides when I bend over to put socks on my feet. Now, I am sure some people are thinking, oh my, why can't this guy put his socks on in at chair or somewhere else. I can. I just prefer this method because I am a creature of habit and I am old. Purchase it if you are young!, but you might reconsider if you over 50 years of age. ... show more
