I was looking for a replacement mattress for my grandsons full size bed. I was visiting for a month and his skinny foam mattress that came with the bed was awful!!! I researched everywhere for a good decent mattress, but not too pricey either. I found this on Ashley Furniture's website, and loved all the reviews, so decided to try it. When I went to complete the purchase, delivery would have been 2 weeks later. There was no point! I decided to see what Amazon had and just by chance put this mattress in the search bar. Same price!!!! Not only that, it was available within 3 days, with Prime FREE delivery, which I would have had to pay for with Ashley Furniture. I chose 4 days as we had plans on that 3rd day. Not only did it come when requested, I was offered free setup and removal of the old mattress at time of purchase! But I was skeptical, no way were they going to set up, they'd drop the box and say thank you ma'am! I was BLOWN AWAY - they arrived and asked `where do you want this ma'am?' They took it upstairs to the bedroom I showed them. Removed the old mattress, unpackaged the new one and it started expanding. They took all the trash and the box, and the old mattress with them. Yay!!! I was happy as a clam. Within minutes you could test out the bed, but we let it expand for 24 hours just to be safe, and because I wanted it to be at its greatest potential. One of the reasons I picked this mattress is I hate those newfangled ones that are all foam! You seem to sink into them, hard to turn, and just downright uncomfortable. This mattress reminded me of my beauty rest. It has separate coils for support, then the foam, pillow top. I don't like firm mattresses, and not super soft, I picked this plush one, its a medium firmness with just enough plush softness to feel comfortable and with some give for a woman's hips as a side sleeper and stomach sleeper. I'm home now in my own bed, but my grandson loves his new mattress! His room is always used for guests too, and my oldest grandson and his girlfriend slept on it and told me it was great!!!! Much better than the old crappy foam. I'm sure I'll get more compliments on it as my daughter has more visitors. Especially will be happy when I visit again knowing I'll get a good nights sleep going forward. My granddaughters now want new beds, same as this one! I've also decided to get one of these for our 5th wheel as it only has a skinny foam mattress. Can't wait to order and then try it out! This is a great mattress, and as I said, one you'll get at Ashley Furniture Store, but won't take as long or cost you delivery fees. ... show more

Size: King Style: 12"
Great bed for the price! Very comfy, on the softer side not firm, bouncy have used for a couple of months now and very happy and would repurchase again for other beds, if you’re on the fence for this or a more expensive bed BUY THIS! Worth it!

    • Very happy with this mattress!
Size: Full Style: 12"
1st MONTH: Arrived quicker than expected. That's always nice! Unpacked and leaned against the wall, since instructions say to let breathe 24 - 48 hours. Reading reviews and a family member's experience with a new mattress, I immediately was focused on any bad smells. NONE. Didn't have ANY smell to it. After close to 60 hours (I wasn't in a hurry), I zipped the mattress protector on it and put it on my frame and added sheets. Couldn't wait to lie down and just feel it. Definitely notice the cushy top layer. But, it was soft and comfortable. It's a solid feel! I moved naturally to see how it felt. My only negative impression was that it's not as firm as I like. BUT - it's also not for me. This was bought for 2 under 10yr old children to use when they stay at my house. Anyway, I have it on a frame that doesn't have a box spring, but is supported by slats. I slept on it the first night and, again - felt that it's not as firm as my actual bed, but I slept well and woke up with no adverse feelings. I can't complain at all. Makes no noise when moving. It's thick enough. It's comfortable. Seems to be made VERY well! The girls spent the night the next 2 nights and the first night - well . . . they ended up in my bed and I ended up sleeping in this one. Again - fell right to sleep and woke up feeling fine. It's still a little cool at night, so no way to make a real impression about the cooling gel. The next night I made sure the girls stayed in the bed, and they're 7 & 8, so they don't care. They slept. It's still VERY early into the life span of this mattress, and truth be told, it probably won't get a lot of use on a regular basis since it's in the extra bedroom. But, I'm happy. It took me months to decide on a mattress. The "Design by Ashley" part was the draw. Ashley mattresses have great reviews. The price was the next draw - holy fatwallets, batman - mattresses are expensive anymore. Amazon customer reviews are the next draw. This one had less legitimate negative reviews than the others in the price range. At this point, if I needed another mattress, I'd look at the other options in the Signature Design by Ashley store. I'm happy with this purchase and would get a more firm model next time. ... show more

    • Great buy
Size: Full Style: 12"
I was just setting up a spare bedroom and didn’t want to invest a lot, so this mattress had good reviews but was under $300 so I was not expecting much. It arrived in a box all rolled up. After letting it expand I was pleasantly surprised this is a really nice mattress! It’s nice quality, looks like a real mattress and not just foam AND it’s actually very comfortable! No complaints here. Highly recommend, again for the price paid. ... show more
