    • Great inexpensive option
Size: King Style: 14 Inch
I was worried about this purchase but so far I am happy. The mattress is just as comfortable as other expensive mattresses I have purchased. The box is super heavy but I was able to open and sleep on it the same night. Great option if you don’t have a lot of money to spend in the big retail stores and you already have the base for it to go on. I am definitely happy I went with the 14” option. ... show more

    • Best. Mattress. Ever.
Size: King Style: 14 Inch
This mattress has some firmness and some softness. I'd say more firm than soft but soft enough to feel yourself sink down into it slightly. Which is what I prefer. The packaging was fairly easy to remove and open for me and the loud pressure release was such a fun sound and put a smile on my face. It's my first new mattress since I was about 5 years old! Couldn't be more pleased! ... show more

    • Perfect when coupled with an inexpensive 1-inch foam topper
Size: Queen Style: 14 Inch
Was also able to use same 14" fitted sheets with the 1" topper but even without a topper, the support of this mattress is great. I just wanted a bit more firmness. Very happy with this mattress. Interesting how it was compressed into a long square box. It arrived clean and dry, but do wait to open it until it's in the bedroom. Opens like a giant can of biscuits or similar to a CO2 inflatable emergency life raft. Great product, great price, great transaction. Love it! ... show more

    • Softer Than Expected
Size: Queen Style: 14 Inch
This mattress is nice and thick, but a little softer than I had hoped it would be. I do use a firm cushion matress topper that helps.

It arrived in a timely manner but was stained near the end of the bed . A very nice quality and super comfortable. Has perfect support and just the right size. Amazing product I just wasn’t happy about the large stain on the corner.
