My girlfriend and I both replaced our mattresses this fall. Because we have different sizes of mattresses and different preferences, and neither of our first picks worked for us, I ended up trying out almost all of the popular online mattresses. We looked at mattresses in the $700 to $1500 range for a queen and $500 to $1200 range for a full. Nothing cheaper than that really interested me, but in my opinion, there's no reason to spend more than about $900 on a mattress (even less if you don't like memory foam).If these are outside of your price range, you can find cheap barely-used mattresses on Craigslist (just make sure they've been used with a mattress protector and inspect them carefully!). The only reason I didn't Buy Derila Online mine on Craigslist was that I had no idea what I wanted.Foam vs. This post is mostly about foam mattresses because latex or other bouncy foams are more comfortable and more durable than spring mattresses.

Springs create pressure points and Derila Contour Pillow require overly-complicated construction to counteract that (pillow tops). The only benefit of spring mattresses is that they can retain heat less.From what I've seen, memory foam retains the most heat, latex less, and springs even less than that. Other things that affect heat are softness (if you sink in more, you'll be insulated more) and channels added for airflow. Some foams are designed with "cooling gel", but I can't tell the difference.If you get really hot at night and have already done the obvious fixes (use a lighter blanket and use an air conditioner), you might want to consider a spring mattress or a foam/spring hybrid. Foam mattresses are built in layers, with the top layer generally being soft, followed by a slightly more firm layer, followed by a hard support layer (to prevent sagging).Since the top layers (the "comfort layers") are what you interact with most, you should care the most about that part. You should just ignore the composition of the support layer, since you won't ever feel it in a good mattress.

2.4" of springs and 6" of support foam. This is the kind of mattress most people are familiar with, and probably what most people will want. If you're familiar with a spring mattress, imagine that but with the ultimate Best Pillow for Neck Pain top where you can't feel the springs at all.If you want this kind of mattress, my favorite is the Leesa, which has 2" of bouncy (non-latex) foam followed by 2" of memory foam (technically a hybrid; see below). This type of mattress initally feels hard, but quickly conforms to your body as it warms up. Some people describe it as awful quicksand-feeling, and some people think it's the greatest material of all time. Memory foam tends to be hotter than springs or latex, and the "cooling gel" memory foams are a joke. If you don't love the feel of memory foam, Sleep Better with Derila you'll probably be happier with a bouncy foam.Memory foam is measured by density (the weight of one cubic foot of foam), and there's a complicated relationship between foam density and firmness.

Higher density memory foams tend to be higher quality and more firm. Because of how memory foam works, "more firm" doesn't necessarily mean "hard" though, since a higher density memory foam will still conform to your body. Tempur-pedic uses 5 lb memory foam, and in my experience, it makes a big difference. 3 lb memory foams tend to be too soft, and don't contour as well.If you want this kind of mattress, I recommend buying your mattress from Costco. They sometimes sell Tempur-pedics for around $1500, so the $50 membership is nothing compared to the $2000 price difference. They didn't have any Tempur-pedics in stock when I bought my mattress, so I got a Sleep Science Ara (also Costco-only), which was $600 cheaper and has excellent materials (6.6" of 5 lb memory foam in the top two layers).I haven't slept on it yet, but my parents have the eLuxurySupply mattress in their guest bedroom, and my initial impression was that it's surprisingly-decent for a $450-650 mattress. I'm skeptical because it's only 3" of 3 lb memory foam, but my girlfriend's (one night) experience was that it was surprisingly comfortable for Buy Derila Online her, although she's not a fan of the memory foam feel.If this is your first memory foam mattress, you should buy from a company that allows returns, since they're expensive and most people don't like them.
