(MONEY Magazine) – THE LAW A lot depends on where you shop. Big-box stores can have lower prices. Independent retailers may be more willing to negotiate the price. Either way, don't be swayed by manufacturers' boasts of greater comfort or beauty. Only your opinion matters.

Catalogues and giant anchor tenants in malls dominate the housewares industry, but while their purchasing power can mean lower prices on some items, most national retailers are locked into a rigid pricing structure, which means no haggling. For independent retailers, however, haggling is not only permitted, it's expected (figure on dropping the price by 15% to 20%). Regardless of where you shop, remember that the only true judge of quality is you. It doesn't make any difference if some salesperson regales you with tales of this cotton's provenance or that sofa's coil count--only your hand and keister can really tell.

ITEM BEDDING

TESTIMONY Thread count is king--the higher the better. The best sheets are made from Egyptian cotton.

REBUTTAL Single-ply sheets (sheets in which single threads are used to weave the material) top out at a thread count of about 500. Any higher and you're probably holding a double-ply or triple-ply sheet (in which two to three threads were wrapped together to make a thicker strand). This can be more durable than single-ply, but it's also heavier, which some people don't like. Egyptian cotton is special only if it's the primo extra-long staple (ELS) kind. Ordinary cotton from Egypt is no different from ordinary cotton from the U.S.

VERDICT Look for single-ply sheets made of 100% pima cotton (ELS cotton from around the world) or supima cotton (ELS cotton grown in the U.S.). For extra softness, opt for 100% cotton sateen, such as what's found in Sears' Everyday Luxe collection, which costs around $100 for a queen set. No matter what you buy, know that you don't have to go much beyond a thread count of 300 to feel babied.

ITEM COUCH

TESTIMONY Designer-name couch for $699! Marked down from $1,299! All prices are final!

REBUTTAL Like clothing designers, furniture designers make different lines for different stores. So the couch you see at a discount store might look just like the posh store's model, but the company took construction shortcuts to keep the price down. (Think outlet vs. retail stores.) Also, about 85% of local stores will give you a discount if you ask (request 20% off), so don't be shy. And in the end, nothing is as important as how a couch feels.

VERDICT Sit on the couch. For a while. If it's a sleeper, fold it out and have a lie-down. Make sure the springs are made of eight-way hand-tied coils for long-lasting support. Look for a kiln-dried hardwood frame (not steel) for durability. Less assembly is good too--the more pieces there are, the more likely it is that things will jiggle over time. A good retailer to start with? Ethan Allen, says Jennifer Litwin, author of Best Furniture Buying Tips Ever!. "Their sales staff is great and their furniture is well-made."

EXPERT WITNESS

ITEM ORIENTAL RUG

BRUCE KITNEY, a New York City rug store owner

"Knot count, or knots per square inch, is frequently talked about, because it's one of the few characteristics you can measure. But it can also be misleading. A Baluch rug with a knot count of 95 is a pretty neat example of the type. But you don't talk about a self-respecting silk rug until you're at around 500 knots. A high knot count doesn't always mean better durability either. High counts tend to go with very complicated designs; the weaver will clip the nap to make it thinner, so you can really see the work. A more loosely woven but thicker rug will last just as long. The best-quality carpet is hand-knotted--not hand-tufted or machine-woven. Hand-tufted rugs are sometimes sold as "handmade," but they're one-sided, so they're no different from carpeting. Machine-woven rugs will usually have some surging, or hemming, and the design won't be as colorful on the back of the rug. Good-value rugs are coming in from China. They use quality wool, and it's a well-made structure. A good Chinese rug is probably floral in design and 175 knots or so, and you'll probably pay $2,000 and up for a typical eight-foot-by-10-foot carpet."
