Mybecca 4-Pack White Polyurethane Foam Cushion Inserts; Square 18x18x1 Foam Tiles for Upholstery Projects, Pillows, DIY Home Decor for Seat Replacement, Padding, Cushions

Worked perfectly for my reupholstering project! Made the seat cozy

I got this as a replacement seat cushion to a small recliner since the one that was in there was probably a good decade old and had started to break down. This one is firmer than the other one was (so perhaps I mis-judged "medium"). It was fairly easy to get into the cover and seems like it will be fine. I haven't spent a lot of time in that chair yet, though (it is downstairs, which is rather chilly in the winter and thus not my usual hang-out for now). When I first sit down, it feels really firm, but then I guess it gradually molds and that sense goes away.

Perfect for what I needed it for

Material is perfect. Made a custome outdoor couch and it is firm, soft, and comfy. Wrapped it with some waterproof material. I was skeptical about it but it was well worth it.

One suggestion when you purchase this, Measure twice. It's not difficult at all to cut it with a little saw or razor but getting it right the first time is the best way. The foam feels top notch and comfortable.

This was great, it did not take it long at all to jump to its full size and I used to redo a couch. For me it worked great and I am very happy. It was also the cheapest I could find and still be the thick pad. Came packaged small and thin, but popped to life very fast, almost right away.

Just stop. Memory foam is not as comfortable as the market makes it out to be. For a bed, sure. A pillow, 50/50. For a seat cushion, total rip off. Think about it. If memory foam was so comfortable to sit on, why don't more sofa's use it? This is what I was thinking while I was sitting on my sofa and thinking why it was so much more comfortable than my office chair.Then it hit me. Why don't I just buy a sofa cushion? So I did and not only is this cheaper it's actually comfortable. It moves around a bit, so maybe sew some fasteners to keep it secured to the chair so it won't slide off, but that's like a $5 craft project. Compare that to the money saved and the use relief on your butt and it's worth it.Sure, some may argue a foam sofa cushion is less durable and will need replacing before a memory foam cushion. Man, I have spent up to $100 on memory foam cushions and NONE have felt good to sit on for any period of time. This cost me about $30+ and it works. I don't care if I have to buy another one in six months, it works. (I probably won't have to buy another on in six months, I'm just saying that for hyperbole to convey my frustration.)

Worked for dog who won't use stairs. He has back issues and will not quit jumping from bed to the floor or sofa to the floor. Needed to minimize the jump.
