This Crate and Barrel sectional has served me well for three years. No pets, children, non-smoking household.
I've used it as a chaise lounge, and it is incredibly comfy and easy to sink into.
Removable cushion covers, and have been washed regularly.
Metal teeth connectors for the two sections, in case you prefer them attached.
Down cushions.
Calming light turquoise color, "Spa" colorway
Can deliver between Santa Clara/Palo Alto area, for additional $20.
