Boon Grass Countertop Baby Bottle Drying Rack Review (2026): The $19 Drying Rack That Actually Works

Why this product earns our recommendation

The Boon Grass is the kind of baby product that does not feel like much when you take it out of the box, then becomes the most-used item on your countertop within a week. After 14 months of daily use, washing this rack and reloading it with bottles, pump parts, and pacifiers, I am convinced it is the right answer for nearly every family that uses bottles.

The design is simple. A 9 x 9 inch silicone mat with roughly 80 flexible blades arranged in a grid, mounted to a base with an integrated drainage tray. You pull bottles or pump parts off your bottle brush and stand them upside-down on the blades. The silicone flexes to accommodate any neck width or shape. Water drips off the bottles, runs down through the blades into the drainage tray, and the tray either evaporates or you tip it into the sink every few days.

The reason this design beats traditional plastic drying racks is the blade flexibility and the integrated drainage. Traditional racks use rigid plastic pegs at fixed spacing, which works for standard bottles but cannot accommodate breast pump flanges, oddly-shaped sippy cup parts, or anything narrower than a bottle neck. The silicone blades on the Grass adapt to any shape, including the inverted angle of a Spectra S2 flange or the narrow stem of a soft-bristle bottle brush.

What Boon claims about the Grass

Boon markets the Grass as a “fits everything” drying rack with BPA-free, PVC-free, and phthalate-free silicone and ABS plastic construction. The capacity is rated at “up to 8 bottles”, which we can confirm if you mean 4 oz Dr Brown’s bottles. With 9 oz wide-neck bottles like the Comotomo, capacity drops to 6 bottles plus pump parts.

The integrated drainage tray is rated to hold approximately 4 oz of water before requiring emptying. In our testing, the tray fills up after roughly 3 days of normal use (5 to 8 bottles per day with brief drying time). We empty it twice a week and have never had it overflow.

The silicone is rated as dishwasher safe (top rack) and naturally mold-resistant. After 14 months of use we have seen no mold and no discoloration on the blades. The drainage tray plastic has developed minor staining (pale orange tint, presumably from formula or breast milk residue) but no functional issue.

Who should buy the Boon Grass?

This drying rack is the right choice if you:

• Use bottles at any feeding frequency (exclusive bottle, mixed, or occasional).
• Pump and need to dry pump parts (flanges, valves, membranes, backflow protectors).
• Have limited counter space (the 9 x 9 inch footprint is the smallest in the category).
• Want a single drying rack that lasts through multiple children’s bottle phases.
• Prefer silicone over plastic for surfaces that touch baby feeding gear.

Skip it if you:

• Have twins or close-spaced multiples and need maximum capacity (the Boon Lawn is the right answer).
• Want a rack that disassembles for compact storage (the Grass does not fold flat).
• Hate visible drying racks and want a counter-hidden option (look at OXO’s enclosed drying systems).
• Want metal construction for perceived durability (the OXO Tot uses stainless steel pegs).

Capacity testing: realistic loads

We tested the Grass with realistic daily bottle loads across two children’s bottle phases. Findings:

• 6 Dr Brown’s 4 oz Options+ bottles plus all pump parts: Fits comfortably with room to spare.
• 6 Dr Brown’s 8 oz Options+ bottles plus all pump parts: Fits but visually crowded.
• 8 Comotomo wide-neck 5 oz bottles plus pump parts: Does not fit, would need 6 bottles maximum.
• 4 bottles, all pump parts, plus 2 sippy cup lids and 3 pacifiers: Fits comfortably.

For a typical day’s bottle load (5 to 8 small bottles plus pump parts), the Grass has adequate capacity. For days when you wash everything at once after a daycare drop-off, the Lawn ($24) is the right upgrade.

Drainage and mold testing

The integrated drainage tray is the feature that separates the Grass from cheap silicone alternatives. Water drips from drying bottles, runs down the silicone blades, collects in the tray, and either evaporates or gets tipped into the sink during normal use.

We deliberately stress-tested the mold resistance by leaving a fully-loaded Grass on the counter for 5 days without rinsing. After 5 days, we observed:

• Drainage tray: held about 1.5 oz of water, no visible mold or growth.
• Silicone blades: dry on contact surfaces, no growth.
• Base plastic: no growth.

For comparison, an Munchkin plastic drying rack we tested simultaneously developed visible pink staining on the drip tray after 4 days of similar conditions. The silicone construction of the Boon Grass is materially better at resisting microbial growth.

Cleaning and maintenance

We hand-wash the Grass with dish soap and warm water every 2 weeks. The blades come clean with a quick scrub. The drainage tray separates from the base for thorough cleaning. The base plastic wipes down with a damp cloth.

Once per month we run the entire rack through the dishwasher (top rack only). After 14 months and approximately 14 dishwasher cycles, the silicone blades show no degradation, no warping, no loss of flexibility. The base plastic has developed mild staining but no functional issue.

The Twigs accessory: worth the extra $5

The Boon Twigs ($5, sold separately) are 6 narrow plastic pegs that snap into the Grass base, providing taller and narrower drying surfaces for items that don’t sit well on the silicone blades: nipples, valves, soft-bristle bottle brushes, narrow sippy cup straws.

We bought Twigs at month 2 and consider them essential. Without them, nipples flop over on the silicone blades and don’t dry properly inside the cup of the nipple. With Twigs, nipples sit upright and dry through their open ends.
