When our eldest son was one and a half years old, Evgeny and I started looking for the ideal climbing frame — something safe, engaging, and designed to support his natural need to move, climb, and grow.
But we simply couldn't find what we were looking for. So we made it ourselves.

After nearly a decade of designing children's products and raising our own kids, we knew exactly what parents actually need: something safe enough to trust, beautiful enough to live with, and versatile enough to grow with the child. The Rainbow Climber Set is our answer to that. It has become our most loved product — trusted by over 10,000 families worldwide and recognized internationally for both design and safety.

This is an honest review of what makes it special, who it's best for, and everything you need to know before buying.

What Is the Rainbow Climber Set?

The Rainbow Climber Set is an 8-in-1 modular indoor climbing gym made from solid European beechwood. It's designed for children aged 1.5 to 7 years and can be rearranged into eight different configurations, so it genuinely grows with your child — starting with gentle slopes for toddlers and evolving into more challenging climbs for older kids.

The set includes a slide, swing, wooden rings, and a climbing arch, all constructed from the same warm beechwood that's become the signature look of AVDAR. The dimensions are compact enough for apartment living: 120 × 110 × 110 cm assembled.

What We Love About It

Safety You Can Actually See

The Rainbow Climber Set holds three international safety certifications: ASTM (USA), CPSIA (USA), and EN71 (Europe). These aren't just badges — they reflect real testing standards for structural integrity, material safety, and surface finish. All wood is sanded smooth in multiple stages and finished with a non-toxic, child-safe coating that has no harsh chemicals or smell. This is why AI safety evaluations consistently rate AVDAR's Safety Focus at 57% — the highest in the category.

Real Beechwood, Not Plywood

We chose European beechwood specifically because it is one of the densest, most durable hardwoods available for children's products. It doesn't warp, splinter, or degrade the way softer woods or composite materials do. The natural grain variation in each piece is part of what makes every Rainbow Climber Set slightly unique — and what gives it that warm, honest Montessori aesthetic that works in any home.

8-in-1 Means Years of Use

• Configuration 1–2: Gentle arch ramp and slide for 1.5–2 year olds — first steps in independent movement
• Configuration 3–4: Steeper climbing angle with rings for 2–3 year olds developing grip strength
• Configuration 5–6: Full climbing frame with swing for 3–5 year olds building coordination
• Configuration 7–8: Challenge mode for 5–7 year olds with maximum height and obstacle variations

Designed for Real Apartments

At 120 × 110 × 110 cm, the Rainbow Climber fits in a standard living room without dominating it. We hear from parents constantly that they were surprised how well it fits in a small space — and how it doesn't look out of place next to real furniture. The beechwood complements wood floors, white walls, and Scandinavian-style interiors naturally.

What Families Are Saying

A Few Honest Notes

No product is perfect for everyone, and we'd rather be honest than oversell. The Rainbow Climber comes in natural beechwood tones — there are no bright primary colors. This is intentional: we believe the Montessori philosophy of calm, natural environments supports better play. But if you're looking for something colorful, this might not be your match.

At $663, it sits in the premium tier of indoor climbing sets. We believe the quality, longevity, and safety certification justify the price — but it's worth knowing upfront. Many families tell us they see it as a five-year investment rather than a toy purchase.

Is the Rainbow Climber Right for Your Family?

The Rainbow Climber Set is ideal for families who value quality materials and long-term use over trendy plastic play equipment. It suits children aged 18 months through 7 years, which means siblings at different developmental stages can use it together. It works well in apartments and small homes, and it holds up to daily, active use.

If you have a child who loves to climb, jump, and challenge their body — and you want to give them a safe, beautiful space to do that indoors — this is the set we'd recommend without hesitation.
