Question: I'm new to memory foam mattresses, what would I put below this mattress?
Document: You can also use this without a box spring, but I wanted the height of 2 mattresses. I'm always hot and was concerned about heat... this was not an issue at all with this mattress compared to a regular spring mattress - pretty much the same &#34;heat&#34; experience I think.I think this is a great option as an introduction to Memory foam mattresses and you can't beat the price. I won't go back to a spring mattress ever!
I'm a side sleeper. I also have pretty bad hip pain. Regular mattresses only aggravate my hip pain, so I started buying Areobeds for daily use. Areobeds were great for my hip pain though they only lasted me between 6-12 months before signs of the dreaded slow leaks, repairs. I decided to try a memory foam mattress. Seeing the good reviews, low price, and Made in America on this one, I went for it.
This mattress is my first memory foam mattress. The quality of this mattress look very good and durable. My first expectation to the foam mattress is that i would sink into the mattress which i might find it hot and uncomfortable, but not this mattress. This mattress felt good not too soft or hard. So far i had no problem adjusting to sleeping on this new mattress. I would recommend this to anyone who doesn't like a foam mattress is too soft.
Mattress arrived on time [actually earlier than Amazon had predicted]. Packaging was excellent. Mattress was of much better quality than I had expected at this price point. Mattress expanded to original size in a matter of minutes. No unpleasant odor from the foam [as some other mattresses exhibit]  Mattress is on the firmer side. You definitely feel the memory foam. All in all an excellent product and excellent seller to purchase from. I would highly recommend.
I looked at the Temperpedics (and air mattresses) recently at a home show and honestly can't tell any difference in quality/comfort in this much less expensive mattress. I do get a MUCH better night sleep and have no body discomfort in the morning now. I should have purchased a memory foam long ago. If I find any longer term problems, I'll be sure to update this feedback, however for the price, if this lasts for only a few years, I would find it worth it.
You could seriously buy 6-7 of these mattresses for the price of a tempurapedic! Would most definitely recommend this product to any one interested in buying a memory foam mattress. Be sure to buy a proper frame/base for it though if you don't already have one.
It would be nice if it was 5 or 6 inches of memory foam, but that will send you into the much more expensive realm of foam mattresses. If you are looking for something that is inexpensive and comfortable, this seems to be a good choice.There was something a bit humorous that came with the mattress, a 8.5x11 sheet of paper with the instructions, and a small note at the bottom saying, "We appreciate it if you give us a 5 star rating."
Some say the smell is bad but we put our mattress cove and sheets on it and 2 hrs late went to bed and the smell way faint. That night wasn't the best sleep just because of the mattress being new but every night since has been a great night sleep. Way better then the spring mattress we owned. If you like a firm mattress I recommend this one and it seller.
BEST mattress I've EVER slept on! I was a bit concerned when reading other reviews, on the firmness, or possible odder of the memory foam. This mattress showed up in a box that was about knee height, and square. Not very big at all. I though, &#34;How on earth is my mattress in this.&#34; How AMAZED I was, when I opened it, and it sprawled out to be my most amazing nights sleep ever. I LOVE my new bed!
I had never slept before on foam mattresses and was a little skeptic (I am from Europe). I thought they could be too weak comparing to spring mattresses. But I am absolutely satisfied with this one. I am ~70 kilo weight, but even if I stay on it is not sag a lot, so I think it is good for heavier people too.I would recommend to buy this mattress to my friends.
Answer: You can use a regular box spring, or an Ikea bed with the slats will hold fine.
