If Nigella Lawson were your girlfriend, your bed would be the most comfortable bed in the world. It wouldn’t look like one of those beds from the catalog — your pillow cases might be mismatched, the duvet would always be rumpled, the bed skirt wouldn’t be aligned correctly so people could see some of the shoes and books accidentally kicked under the bed — but it would be the perfect balance between firm and pillowy, with sheets that were both crisp and nicely worn in.
