Some example images will help to understand your problem. It is hard to help you without that because no general solution for object detection exists.

pls help...can we apply here SIFT technique

I don't think SIFT will help you much, because each bed may appear completely different in each image: different angle, different illumination, sheets, pillows, or other objects on the bed. And so on and so forth. There will be very few points (if any) with similar SIFT features. It seems like an extremely complicate problem, unless you have some prior knowledge that may help in detection.

I think one of the best approaches is to use DPM.
It is the state of the art algorithm for object detection since it's publish date.

If speed is one of your concerns use HOG feature and a linear SVM.
