    • Amazing Quality

Review Image by midgee midgee
The media could not be loaded. Originally I got this mattress as a cheap alternative to tie me over until I could make a decision on buying a new mattress. The prices of mattresses these days are so overwhelming. I read all the reviews and I compared the structure to expensive name brands. I have never made a better purchase! The quality for the price is unbeatable. I was surprised at how firm it is as I expected it to be flimsy. Not at all! It’s firm but has a very nice soft top. Everything about it is exactly like the description. The set up was easy and fascinating. As hard as it was I did let it sit in my living room for 3 days before putting it in my bedroom. My sleep has improved and I move a lot less during the night. My back pain has also improved. ... show more

    • The right choice - Love it
Size: Queen Style: 12 Inch
Perfect- exactly as it is shown. It exceeds my expectations, it is very good quality, firm but also pillow soft in the right places. Easy open and a perfect value for the money. I will purchase again from this maker.

    • Great value!
Size: King Style: 12 Inch
Super nervous buying a mattress online without testing it, but this mattress is so good. It’s not super firm – more medium firm – but very comfortable!

    • Great bed great price
Size: Queen Style: 12 Inch
This bed is comfy and great for the price. No bad smell either. I gave it 4 stars because it says medium firm but it is not. This bed can easily be named medium soft, if not just soft.

    • Better than expected. Love the Mattress thru & thru.

Review Image by Navie Rou Navie Rou
Love this mattress! Better than what I originally thought, and I thought I wouldn't like it. I was wrong! It's not too plushie, or too firm. It is just the right balance (For me, at least). I do recommend this brand of mattress! Nothing has been wrong with it. The support, functuality, durability is 100/100. I do love that when I unpacked my mattress, it really inflated less than 5 seconds to its full size. I didn't have to wait at all . ... show more

    • Great, but not medium firm!
Size: Full Style: 12 inch
A good quality mattress for our toddler but compared to our Nectar mattress it is not “medium firm”. This mattress is cushy and bouncy, comfortable but not for someone looking for a firm mattress.
