  • Best-value dog beds ever
Size: Twin Style: 3" Pattern Name: Original Box
Pro-tip for people with large dogs, a lot of dogs, or dogs with joint issues: rather than spend tons of money on expensive, poor-quality dog beds, just buy a mattress topper like this and cut it into custom dog beds. I personally waited for the 3in twin topper to go down to about $30, cut it in thirds, made covers out of a waterproof mattress cover (although I've since learned you can buy waterproof dog bed covers), and wrapped the sections in old flat sheets until I make fancy outer covers. For the price of one decent bed from Petco, I got three out of this. As for the quality of the topper itself, it seems really great. After letting it lay out to expand and air out on a table for a couple days (just me waiting for crafting materials to come in, it didn't necessarily need the extra time), it seemed to come up just a couple inches short of regulation twin size, but that seems pretty normal for toppers. The plushness feels really good, and takes a moment to regain shape as per memory foam. The smell does seem to linger, but it's no more strong than an actual new bed, and after airing it out and then putting mattress covers, sheets, blankets, etc, on, it shouldn't be noticeable to a human (it certainly doesn't bother my dogs). I also keep one of these makeshift dog beds under my desk, and have noticed that it does seem to get rather warm when I rest my feet on it (because it is super comfy). ... show more

  • Great Egg Crate Foam Mattress Topper...I can sleep again!
Size: Twin Style: 2" Pattern Name: Original Box
I bought two of these mattress toppers in twin size to use on top of old mattresses at a cabin in Maine. They arrived wrapped up, but a little bigger than I thought, so I only packed one. It worked out very well. I am a light sleeper & worried about tossing & turning all night on an uncomfortable mattress in a cabin with little privacy. Instead I put in ear plugs and snuggled down in comfort on the soft and fluffy mattress pad. Fhat.pad was left as.a gift to the cabin. But I liked it so much I put the other twin on my half of our new firm king size foam mattress. Magically I started sleeping much better. No more turning to get comfortable, no more leg pain in the morning. I was able to sleep through the night. This topper makes a firm mattress softer and alleviates pressure points. The pads arrived partially wrapped in plastic so I left them out in our entryway for 4 days before we went to Maine. That allowed them to outgas most of the noxious foam odor they have. The second pad was thouroughly aired in my sunroom for a few days. I am sensitive to smells and I can say that you really do have to air out any new foam a few days before use. I also use the topper under a mattress pad. With the 2" foam I was able to use our deep pocket sheets. To those who don't have a good washable mattress pad, just get one now. I would never put sheets right over a mattress or foam topper. I loved the nice packaging and the sweet note from the company. I am thinking of ordering another topper from this company for one of our other beds. Maybe I'll try the 4" foam next! ... show more

  • Good and bad
Size: Full Style: 2" Pattern Name: Original Box
I've had the 2 inch for about a week now. Before you open the box decide where you'll be laying it down to fully de-compress which takes roughly 24hrs. You need to be gentle with it when you take it out of the box and begin to unroll it while it is still in the plastic sheeting. It comes folded in half and then rolled up so it looks small. I gently cut the bottom of the sheeting and it started to expand a little. I slit it open along the edge of one side to let it expand. When I tried to separate the foam (it is folded in half) I found it sticks together. If you're not careful it can rip. I did it a little at a time every 10 minutes or so as it was expanding. Eventually I cut along the other side of the plastic sheeting and unfolded the plastic which made a large sheet of plastic that was protecting it from my living-room floor. You need to let it lay somewhere to fully expand so plan in advance where you will do that...best to have a spare room away from kids or pets. You could put it on top of an old blanket or a drop cloth if you don't want to take the time to open the plastic the way I did though. When I put it on the bed the next day, I was surprised how the 2 inches made it actually harder for me to get into my bed so BEWARE of that if you have thick mattresses or are buying it for an older person. I really can't sit on the edge of the bed anymore like to put on socks without a struggle. I'm 5'3" It seems pretty comfortable compared to having the mattress poking me....but then again, I finally got around to rotating the mattress and that could have helped too. I put this foam pad over my regular mattress pad. I knew there wasn't going to be enough room to put it underneath and I saw some questions about the product where people wondered that. There are no instructions on the subject in the box but there are 3 blank greeting cards in there? One is a thankyou card you write your own message and two Hello you blank cards. They seem very high quality for cards but without envelopes they are pretty useless....and who really sends out those cards anymore? I felt a little guilty throwing them out but I am trying to fight my clutter habits. Although I guess it was a nice gesture, it seems wasteful to include them. Laying on the bed feels nice. I do sink in after a few minutes but it is still comfortable UNTIL I start tossing and turning which I do often. My problem is it somehow makes it a little harder to support myself with my arm to flip myself. I've been having some shoulder pain in the mornings and it could be that or many other things but the truth is every night I start off saying this is really nice and every time I get out of bed I say I don't like it. It is a cheap fix to an uncomfortable mattress. Because it's hard for me to dig my heels in or my arm into the mattress to turn myself, I can only guess that is why some people say their pad ripped. Just wanted to give a review because I find reviews very helpful when shopping. Something to consider if you are buying this for an older person or someone with a disability. ... show more
