I am re-doing my dining room chairs and would like to know if 5lb. density 2.5 in. memory foam would be a good choice or should I just go with medium firm 2.5 in. regular foam. I am going to wrap the foam in batting before I put the fabric on the chairs. Also would 2.5 inches be thick enouph or should I do 3 inches? Please give details as to which foam would be better and why.
No you need upholstery foam because you want it to keep its shape
Memory Foam Dining Chair Cushion
I would stay away from memory foam for dining chairs. Folks move around, get up, sit down too often for there to be any benefit to having memory foam on a chair, and I can see where it would be a major PITA (literally!) to not be able to turn in my chair comfortably or to have to REsit myself in the molded-to-my-bottom cushion after getting up to get more rolls, or whatever. I'd use regular medium density foam and I wouldn't use more than a 2 slab of it... especially if you're going to wrap the foam w/ batting before applying fabric. If the cushion is too high/bulky you risk folks having to dangle their legs off the edge of the chair (think of Lily Tomlin's Edith Ann sitting in the big chair), or having an uncomfortable pressure point at the back of their thighs that could cause legs to go numb.
