Amazon Basics 9-inch Queen Foam Eurotop Mattress - CertiPUR-US Certified for Comfort & Support - Perfect for Guest Rooms, Dorms & Small Apartments

I was a little skeptical, especially given the price. But I was really pleasantly surprised. Comes vacuum sealed and rolled up. Trick to opening it easily is to unroll the outer shrink wrap, then for the bag, cut the 2 long sides open first so it starts to fluff up, then cut 2 short sides open. Once fully expanded, just pull out the bottom wrapper.I own a Lucid 8” foam mattress before and only complaint is the sides tends to sag a bit when I sit on the edge.This bed expands to 7 in and as described, even if I sit or lay on the edge of the bed. The side does not collapse and I am an average size adult woman. Exactly what I want.I would describe this mattress as firm, but not super firm. Perfect for my daybed/trundle. Love it!!!I was not terribly picky when I bought a mattress, knowing I would have an at least 2 inch gel foam memory topper over it. This product is thick enough that with the box frame I bought and the topper, I don't feel like I am sleeping on the floor.I was skeptical about this style of mattress but ending up getting another one for my guest room. Not sure about the other sizes, but the 11” deep Queen and Full beds are super comfy. I thought with just foam inside it might be too soft/not supportive enough, but they’re perfect and I saved myself about $800 dollars (in aggregate) by getting these instead of the $600 traditional mattresses I had been looking at. Do not hesitate, for the price they are awesomeI was a little scared when this came in because the box was so light m. But once it was all laid out, the mattress expanded to the right size (9 inches). I left it to air for a day or so and no issues so far, very comfy.I’m not going to lie, this is the first mattress ordered online. I was very skeptical about this from the start. To my surprise it is much better than I thought. Very comfortable to lay on and is great for my 3 year old son. Didn’t have any issues with it filling out. I would buy again and probably will with my younger son.I’ve owned expensive mattresses and I can’t see any discernible differences when factoring in the value here. The edges of the mattress aren’t as sturdy as more expensive ones, but if you’re sleeping out on the edge you’ve got bigger problems than your mattressI love this mattress. I use it for everyday and have had no issues. It’s comfortable and firm! For the price, get a mattress topper also if you need to for an extra layer of comfort but I love it!Bought 3 bed and they're very comfortable and clean in sealed packaging.
