Stone, Steel and Iron: Thirstystone Coasters and Holders Compared

The Thirstystone sandstone set is the plain one. You get four round coasters, each four inches across, cut from natural sandstone and backed with cork. The brand describes the stone as naturally absorbent and heat tolerant, and says the cork keeps scratches off your furniture.

Absorbency is the reason to buy stone, and buyers back it up. One reviewer says condensation soaks into the stone instead of sitting on top, and several describe a glass that lifts away without sticking or dripping. A Florida reviewer sets iced drinks on sealed marble and teak furniture and says the water goes into the stone before it reaches the cork.

A reviewer who drinks spirits with ice reports the same: no pooled water and no stuck glass. That is the happy case.

Absorbent doesn't mean bottomless. A desk user who runs coffee, iced drinks and tea across a workday says a ring of moisture shows on the stone when a drink sweats, though it never leaked onto the desk. That reviewer adds that these are porous stones holding a limited amount of fluid.

For a long party, plan on swapping coasters instead of trusting one to take it all.

Durability gets the strongest testimony. One Canadian buyer says theirs are about ten years old and look new. Another says an earlier Thirstystone set lasted about 30 years before one finally stained.

Stone has a weak spot, though. A reviewer who has bought many sets says a dropped coaster is likely to break. Another received a few chipped along the edges, and a replacement box that came soon after had no chips.

Stains are the other complaint. A three-star reviewer wrote only that the coasters work well but stain easily, and called them expensive for the product. That fits what you would expect of an absorbent stone.

The surface is also rougher than a smooth coaster. One buyer warns that glassware with delicate bases needs care when you set it down.

Two smaller points. The cork doesn't run to the edge, one buyer notes. They like that you can't see it, but say you can scratch furniture if you handle the coaster carelessly.

And color varies. One reviewer ordered tan and got multicolor, and another says the photo suggests even speckles while the plain natural stone varies from coaster to coaster. Expect each one to look a little different.

Care is short: the spec sheet says hand wash only, and that a damp cloth or sponge cleans them. Skip these if your glasses have thin bases, if you want a surface that never marks, or if you have a tile floor and clumsy guests.

The Thirstystone marble set is the dressy one. You get four coasters, each four inches across, in white marble with a gold edge and non-slip feet underneath. The spec sheet puts the set at 1.6 pounds.

The brand calls the stone naturally heat tolerant and says every coaster has its own pattern.

Start with a mismatch. The title says round, the bullets say each coaster measures four inches square, and buyers mention both round and square versions. Check the shape on the product page before you order.

One reviewer goes further and says these look like white quartz, with no marble veining. They were still happy, calling them beautiful and good quality in person.

Buyers like the weight and the look. Reviewers use words like sturdy, thick and heavy. One says every coaster is an individual piece, so they differ a little but still read as a set.

Another says guests always comment on them. A reviewer who hand washed theirs reports no problems and likes the feet on the bottom.

Absorbency is where we pause. The brand talks about heat tolerance and surface protection, and never says the stone soaks up water. One reviewer says they absorb some condensation, contrary to other reviews, but less than the original Thirstystone material.

If you want a coaster that drinks the sweat off a glass, the sandstone set is the closer match.

Staining is the sharpest complaint. A one-star reviewer returned the set twice because a gold ribbon tied across the stack left a yellow stain on the top coaster. Another reviewer saw yellow on two of theirs.

We can't say what causes it. We wouldn't tie a ribbon across the top coaster, though.

One buyer sealed the top of each coaster with a stone sealer from a hardware store. They report that a ring wiped right off and the color didn't change. That is one buyer's fix, not a brand instruction, and the product page says nothing about sealing.

Value splits opinion. A three-star reviewer found the coasters more rugged than expected and not worth the price, noting marble ones for far less at a discount store. Others call them affordable.

Care is hand wash only. Pick these if looks lead your list. Skip them if absorbency does.

The stainless set is the odd one out. You get six round steel coasters, each four inches across and a quarter inch thick, plus a holder that keeps them stacked. The spec sheet lists a weight of 8 ounces and says hand wash only.

The brand says the steel resists rust and handles hot drinks without warping. It also says the coasters trap condensation and spills before they reach the furniture.

Steel behaves differently from stone. It can't soak anything up, so water stays on the surface until you wipe it. That is fine for a quick coffee and tedious for an evening of iced drinks.

Buyers like the look. Reviewers say the coasters look modern and clean, and one says they suit a stainless appliance kitchen. Several say they are easy to clean and don't break when dropped on the floor.

One likes getting six in the set instead of the usual four. That counts for something if you host.

The complaints are consistent. One reviewer says the coasters show water marks and fingerprints, so they need wiping after each use. Another says drinks leave marks on the stainless and that they wipe them off constantly.

A third says a sweating iced drink dries into spots, wonders how long those will keep coming off, and wants a coating.

The holder gets mixed reviews too. A three-star reviewer says the coasters fit it so exactly that pulling one out, or putting one back, takes a moment. They wish they had gone with another product.

A four-star reviewer adds that a hard glass on the hard steel top can make an unpleasant noise, though the bottom has soft padding. If you like a quiet table, that matters.

Finish is a risk. A two-star reviewer found a cheap feel and unfinished edges. Most reviewers disagree, and about 70 percent of ratings are five stars.

Who should buy it? A modern kitchen, a desk where you want something that survives a drop, or a host who needs six.

Who should skip it? Anyone who won't wipe up after each drink, and anyone who serves iced drinks all evening.

The cast iron holder isn't a coaster. It is a small stand, 5.13 inches square and 2.25 inches tall, in a bronze finish. It sits on ball feet, and each foot has felt on the bottom to protect your surfaces from scratches.

The brand says it holds four round coasters between 4 and 4.25 inches across, and works with stone, cork, ceramic or sandstone.

What it solves is clutter. Loose coasters slide, wander and end up in a drawer. A holder gives them an address on the coffee table.

The brand calls it lightweight and compact and says a damp cloth or sponge wipes it clean. The spec sheet lists the weight at 0.13 kilograms.

The most-cited problem is height. One Canadian reviewer says the sides are tall enough to cover three coasters, and the fourth stands above the holder. They wanted a taller stand so all four sit inside.

So the holder holds four, but it won't hide four. For a neat, enclosed look, plan on three, or accept a stack that peeks out.

Fit gets praise. One reviewer says it fits their sandstone coasters perfectly and adds a nice touch to a coffee table. Another says it fits their coasters perfectly and nothing more.

A third calls it stylish and says it works fine. The star breakdown tells the same story: about 84 percent of ratings are five stars, and the one-star share rounds to zero.

The written reviews are short, and the critical ones are few. One buyer who bought it as a Christmas gift expected a box and was let down that it didn't come in one. They called the quality cheap, though they said it will work.

If you are giving it as a gift, plan to wrap it yourself.

It also matters what you put in it. The stainless coasters from the other set ship with their own holder, and the product page for this iron one says nothing about them.

Check coaster size against the 4 to 4.25 inch range before you buy. Skip it if your coasters are square or larger, since the product page names round coasters only.
