Now's the time to make sure those heavy flannel sheets and wool blankets of winter are tucked away in storage and replaced with lighter, breathable fabrics for summer.

Materials are crucial. "I like to use cotton and linen," says Denise Rinfret, president of The Rinfret Group, an interior design company based in Manhasset and Manhattan.

"One thing I think linen adds, especially for a summer bed, is texture," says Nancy Pearson, principal of Nancy Pearson LTD, an interior design company based out of Manhattan and Southampton. "The texture of linen makes me think of fresh grass and about being out in nature."

It's also nice to have more than one layer on your bed, especially for chilly evenings, designers say. A cozy throw or coverlet should be within easy reach to add both a touch of warmth and texture. Just because the temperature soars during the day doesn't mean that evening breezes (or overactive air-conditioning) won't bring cooler temperatures at night.

Here are two beds dressed for the season.

THE AFFORDABLE SUMMER BED

Styling an elegant, budget-friendly summer bed doesn't have to cost a fortune. The main focus should be on buying natural fibers such as cotton. For this master bedroom in Atlantic Beach, decorator Denise Rinfret says she wanted to keep the feeling simple and light while still providing a bit of comfort for cooler nights since the home is on the water. "The pillowcases, sheets and the duvet cover are all from Pottery Barn," says Rinfret. The 280-thread-count cotton percale Pearl Embroidered Sheet Set featured here starts at $119.99 for a twin set, and the embroidery is available in eight different colors. To add layers, Rinfret brought in two Metropolitan Grey Langdon Shams bought on sale for $91 each at the Ralph Lauren Outlet and had them embroidered at the Initial Shop in Port Washington. "They can do any kind of print you want, and it's only $15 per pillow," she says. To add color, and account for occasional chills, Rinfret used a Sferra cotton throw ($95 from Gracious Home) at the foot of the bed. "We used a thick herringbone cotton with fringe, because when the bed is all white, you want a pop of color," she says. Rinfret also notes that summer weight duvets from Ikea are an excellent and inexpensive option (starting as low as $7.99) for warmer months. "It's just as good as any quilt you could find," she says.

THE LUXURY SUMMER BED

If you're going to go all out on summer linens, thread count is less important than feel, says designer Nancy Pearson. "I have clients who have said they got 550-thread-count sheets on a discount website, and then I felt the sheets and they felt like burlap," she says. For her own master bedroom in Southampton, she chose black-accented white Lowell sheets by Matouk. "They're made of the finest Egyptian cottons, and you can get them in any color," she says. The cotton percale sheets are woven in Italy, and run about $399 for a twin/queen flat (available through Long Island retailers, including Lagoon Linen in Cedarhurst and English Country Antiques in Bridgehampton). She also used Terra linen euro shams, also from Matouk ($99 each) as well as a matching Terra linen Matouk duvet cover ($448 for queen). After her sheets, Pearson layered on a silk Designers Guild coverlet from Elegant John in East Hampton ($720). "This silk white coverlet reverses to a graphite gray," she says. Then she began to add color and texture. For fun, she used two Mongolian lamb pillows ($500 each, from Home Nature in Southampton) and a single, colorful Hiranya Cobalt Throw Pillow Designer's Guild ($180). Finally, she tossed on extra blankets: a fluffy white merino wool Cloud Throw ($1,065, Home Nature) and a hot pink baby alpaca blanket (her own).
