    • Excellent Mattress – Great Value for the Price!
Size: Queen Set name: 12 Inch
Review Image by binghang zheng
Review Image by binghang zheng
I’m very happy with this mattress! It arrived well packaged and expanded to its full size within about 24 hours. There was little to no odor after opening. The medium-firm feel is exactly what I was looking for. It provides excellent support for my back and hips while still being comfortable enough for side sleeping. The pocket coils do a great job minimizing motion transfer, so I’m not disturbed when my partner moves during the night. The mattress feels breathable and comfortable, and the top fabric is soft to the touch. After sleeping on it for several nights, I wake up feeling well-rested without any back or shoulder pain. For the price, the quality exceeded my expectations. I would definitely recommend this mattress to anyone looking for a comfortable, supportive, and affordable hybrid mattress. Great purchase! ... show more

    • Probably the best mattress I’ve ever had
Size: Queen Set name: 12 Inch
Honestly, I slept like a baby. That says a lot about this mattress coming from someone who almost always deals with sciatica. 10/10. Amazing for the price. BUY IT!

    • Fantastic Hybrid Comfort and Value
Size: Full Set name: 12 Inch firm
Setting up this hybrid mattress was an incredibly smooth process right out of the box. The bed expanded to its full twelve inch thickness almost immediately after I cut the plastic open. I was thrilled to notice absolutely zero harsh chemical odors which is a huge relief when buying a bed online. The materials feel very high quality and the entire expansion process was totally stress free. Sleeping on this mattress has been a wonderful experience thanks to the perfect medium firm feel. The hybrid design flawlessly balances the bouncy support of traditional springs with the deep pressure relief of soft foam. The pocketed coils provide outstanding lower back support while the top foam layers perfectly cradle your joints. Motion isolation is another massive highlight because I never feel my partner or my dog moving around during the night. This bed is a remarkably solid choice for anyone upgrading a guest room or a teenager's bedroom. It delivers a genuinely restful night of sleep for a very reasonable and fair price. You get all the premium features of a thick hybrid mattress without spending a fortune at a traditional furniture store. I highly recommend it to anyone seeking a supportive and comfortable bed on a budget ... show more

    • super thick & comfy

Review Image by gloria & diamond
i was super happy as soon as i set up this mattress. most box mattresses that i have bought in recent years need a mattress topper in order for it to work with my body. (i prefer a firm base with a softer top.) this one was a 2-in-1 for me. i was surprised at how durable and strong the coils felt, and coupled with the thickness of the mattress, it really knocked it out of the park, high quality. immediate good value for the price. i'm sensitive to smells & off-gassing, and i did not feel at all overwhelmed with the smell as it expanded. i especially liked being able to maneuver the box easily to the room i was setting it up in, and then easily getting it out of the box and expanded. the size fit literally perfect in the very particular space i had (boxed in on three sides) and i have recently been using it as a comfortable day bed. so - firmness and soft comfort together is a real win for me. ... show more

    • Comfortable with good support, no weird smell
Size: Full Set name: 12 Inch firm
This has a pretty balanced medium-firm feel. There’s enough cushioning on top to keep it comfortable, but the pocket coils underneath give it solid support and keep it from feeling too soft or sinky. The surface feels nice, and the mattress has a more substantial feel than I expected from something that comes compressed in a box. I threw a mattress topper on it and it balanced out nicely. Motion transfer is controlled well, and the edges feel supportive enough that the usable sleep area doesn’t feel reduced. It expanded normally after opening and was easy to get set up on the frame. For someone who wants a somewhat firmer hybrid without going all the way to a hard mattress, this hits a good middle ground. ... show more

    • A Little Firm, But My Son Likes It
Size: Full Set name: 12 Inch firm
My Teenage Son Really Likes It We put this mattress in my teenage son’s room, and he has been really happy with it. He says it is a little on the firm side and not as plush as some mattresses, but that hasn’t been a problem for him. He actually likes having a firmer mattress, and he uses several plush blankets on his bed anyway, which gives him the softer feel he wants. It arrived compressed in a box and expanded without any problems. After giving it some time to fully expand, it has been comfortable and supportive for him. He also seems to move around less and sleep more comfortably than he did on his 20+ year old mattress. Overall, this has been a good mattress for my son. It may not be the choice for someone looking for a really soft, sink into it kind of mattress, but the medium firm feel has worked well for him. I’m giving this 4 stars because of the firmness. My son is happy with it, but it is a little firmer and less plush than what I would consider ideal. ... show more
