Compare Our Natural Remedy: Unit Block Rx Booster Sets
When selecting your set of unit blocks, consider your short-term and long-term block play needs.
How many children (and their adults) do you want to be able to play simultaneously without creating play-disrupting competition for basic block shapes? Short-term? Long-term? Ideally?
You may want to accommodate one more child in the block area — or want to add a few more pieces to supplement the unit blocks you already have.
Imagine you have a CP11 Introductory Family Unit Blocks Set for 2 toddlers, or CP31 Preschool Center Unit Blocks Set for 3 preschoolers, or CP61 Quarter Classroom Unit Blocks Set for 4 to 5 students. Or you have an existing F151 Introductory Set, G431 Preschool Set, and G461 Quarter School Set from Community Playthings.
You can extend the use of your current set of unit blocks by adding a RX10 Quarter Remedy Unit Blocks Set, which includes one each of the four smaller Carolina Pratt Rx Unit Blocks Sets.
These sets add "missing" and high-demand pieces to standard unit block sets.
Our Hard Rock Maple Unit Blocks are known for their exceptional craftsmanship and quality. Compared with Standard Unit Blocks offered by leading preschool equipment manufacturers and toy importers like Community Playthings. Compare our precision hand-cut Standard Unit Blocks with Melissa & Doug #503 60 Standard Unit Blocks.
We use only durable, infant-safe Hard Rock Maple for our unit blocks — never imported, chemically treated rubberwood or other soft Asian hardwood. We precision manufacturer each unit block to within one-half of one hundredth of an inch, not using cheap labor but using our own hands, right here in Asheville, North Carolina.
Buy with Confidence
Our Hard Rock Maple Unit Block Stock is never treated or sprayed with anti-fungals or insecticides because doesn't need to be — Hard Rock Maple hardwood is naturally insect- and mold-resistant. When your maple unit blocks get soiled, just wipe them off with a damp cloth and let them air-dry. Hard Rock Maple Unit Blocks typically last for decades when periodically cleaned and kept indoors. (We have some blocks that are almost a century old.)
We’ve taken an American education standard — the Unit Block — and provide a better block — locally-made, sustainably produced, precisely and lovingly made, and ultimately safer for our children.
We use only the time-tested proportions of the Standard Unit Block developed by educator Caroline Pratt one hundred years ago: 5.5 inches long, 2.75 inches wide, and 1.375 inches thick. Every block we produce is based on multiples of these basic measurements.
We precision cut each block to within one-half of one hundredth of an inch and chamfer each edge with a roundover bit for safety.
We use responsibly harvested, kiln-dried FSC® Certified Hard Rock Maple, the only material we believe to be suitable for the full range of builders, from infants who put everything in their mouths to older adolescent siblings who build as high as they can reach.
We offer an industry-leading 10 Year Warranty.
We make it easy to upgrade. You can start with a smaller set to meet immediate needs and upgrade whenever you wish. All out sets are modular. It's easy to build a larger set from smaller sets purchased at different times.
