Boon Grass Countertop Baby Bottle Drying Rack Review (2026)

Why you should trust this review

I bought the Boon Grass at retail and have used it daily through two children’s first eighteen months. Boon did not provide a sample and had no idea I would write about it. This is the rack that lives on my counter and gets loaded and reloaded with bottles, pump parts, and pacifiers every single day, so the durability and mold notes here come from actual long term use rather than a quick first impression.

Fourteen months in, with a second child’s bottle phase now starting, I have seen how the silicone ages, how the drainage tray holds up, and where the capacity limits actually bite. That is the kind of horizon that separates a rack that survives one baby from one that survives several.

How we evaluated

I used the Grass for real daily bottle loads, not staged ones, drying anywhere from five to eight bottles plus a full set of pump parts on a typical day. I deliberately stress tested mold resistance by leaving a fully loaded rack on the counter for five days without rinsing, then inspected the tray, the blades, and the base for any growth. I ran the same five day test on a cheaper plastic rack alongside it for comparison.

I also tracked capacity with specific bottle types, hand washed the rack every couple of weeks, ran it through the dishwasher monthly, and checked the silicone for warping, stiffening, or discoloration over the full fourteen months. Anywhere a number appears here, it came from that ongoing use.

The flexible blade design beats rigid pegs

The Grass is essentially a nine by nine inch silicone mat of roughly eighty flexible blades on a base with a drainage tray. You pull a bottle off your brush and stand it upside down on the blades, which flex to grip any neck width or shape. That flexibility is the entire reason it outperforms traditional racks. Rigid plastic pegs at fixed spacing handle standard bottles fine but choke on breast pump flanges, odd sippy cup parts, or anything narrower than a bottle neck.

The silicone blades adapt to all of it, including the awkward inverted angle of a pump flange or the narrow stem of a soft bristle bottle brush. After fourteen months and around fourteen dishwasher cycles, the blades show no degradation, no warping, and no loss of flexibility. That is the part that surprised me most, because silicone baby gear often stiffens or stains, and this has done neither.

Capacity is the real limit

Boon rates the Grass at up to eight bottles, and that holds if you mean small four ounce bottles. With realistic loads the picture is more nuanced. Six small Dr Brown’s four ounce bottles plus all the pump parts fit comfortably with room to spare. Six eight ounce bottles plus pump parts fit but look crowded. Eight wide neck five ounce bottles do not fit, you would top out around six. A mixed load of four bottles, all pump parts, two sippy lids, and three pacifiers fits comfortably.

For a normal day of five to eight small bottles plus pump parts, the capacity is fine. The footprint is the smallest in the category, which is the whole point if your counter is crowded. The trade is that on the day you wash everything at once after a daycare drop off, the Grass fills up and you will wish you had the larger Boon Lawn. Know which kind of household you are before you buy.

Drainage and mold resistance hold up

The integrated drainage tray is what separates the Grass from cheap silicone knockoffs. Water drips down the blades, collects in the tray, and either evaporates or gets tipped into the sink. The tray holds roughly four ounces before it needs emptying, and in normal use it fills after about three days. I empty it twice a week and have never had it overflow.

My five day no rinse stress test is the real evidence. After five days the tray held about an ounce and a half of water with no visible mold, the silicone blades were dry on their contact surfaces with no growth, and the base plastic stayed clean. The plastic rack I ran alongside it developed visible pink staining on its drip tray after only four days under the same conditions. The non porous silicone is materially better at resisting microbial growth, and that is the single biggest reason I trust this rack over plastic.

The Twigs accessory is close to essential

The one real gap in the base rack is nipples. Left on the flat silicone blades, nipples flop over and do not dry properly inside the cup. The separately sold Twigs accessory snaps into the base and adds tall narrow pegs for nipples, valves, soft bristle brushes, and narrow straws. I bought Twigs at month two and consider them part of the package rather than an optional extra.

With Twigs in place, nipples sit upright and dry through their open ends, and the awkward small parts that used to puddle now drain cleanly. It is a small added cost, but it closes the only meaningful weakness in the design. If you are buying the Grass, budget for the Twigs at the same time.

Who should buy the Boon Grass?

Buy it if you use bottles at any frequency, if you pump and need a rack that holds flanges and valves, if your counter space is tight and you want the smallest footprint in the category, and if you want one rack that lasts through multiple children. It is also the right pick if you simply prefer silicone over plastic for surfaces that touch feeding gear.

Skip it if you have twins or close spaced multiples and need maximum capacity, where the larger Boon Lawn is the better answer. Skip it too if you want a rack that folds flat for storage, since the Grass does not, or if you want metal construction and would rather have the stainless pegs of an OXO Tot.

The verdict

The Boon Grass is the rare baby product that justifies its place across years rather than weeks. After fourteen months and a second baby, the silicone has not molded or discolored, the tray still drains correctly, and the blades are as flexible as day one. Its only honest limit is capacity on heavy wash days, which is exactly why the Lawn exists for bigger needs. Pair the Grass with the Twigs accessory, keep the tray emptied a couple of times a week, and you have a compact drying rack that simply works. For most bottle feeding households with limited counter space, I would buy it again without hesitation.
