I don't think two ottomans in a large space sounds weird at all. I personally am more comfortable with my legs straight out than lower. If you have two people using the space who like to sit in a chaise, then the ability to make both ends into chaises actually makes sense. The ability to move one or both so you don't have to walk around them when they are not being used that way makes it more flexable. Some of the "bench" ottomans they make are quite long also. These ottomans can be used in the same way, one at a time or both.

I find men in particular for some reason, alhtough some women as well, are more likely not to like their feet out straight. Some people love to work on their computers, read and watch TV in bed. Others do not. Those that do, are comfortable with a flat surface and not having their legs lower than the seat. It really isn't that uncommon. Just isn't for everyone. The idea that they could use the sofa that way but also move one or both ottomans away to a coffee table type position or even off to the side or as an extra bench seat or removed when they wanted to seems like a versatile solution to me. I know someone who has sectional with a chaise at one end plus an ottoman, and you know what? I recently saw a picture of her on that sofa with the ottoman but right next to the chaise to make a large "double" chaise or "day bed" and she was on it with her two boys reading and cuddling. They looked quite comfortable, every one of them.

Different people are simply comfortable in different positions, and have different life styles and enjoy different things. If getting on the chaise or bed with your significant other or children and cuddling up to read or watch TV is something you enjoy doing often and you have a room large enough to accommodate it, then it makes sense to take that into account when you buy furniture, IMHO.

Might not be house beautiful magazine style, or then it might, lol, but if it works for you and your family, I say go for it.

JMHO.
