Great quality, assembly takes time

The craftsmanship is excellent, and the finish is smooth with no rough edges. Assembly took about an hour longer than expected, but the instructions were clear. Very happy with the purchase.

Nice design, slight color variation

The bed is functional and well-made. The natural oak color was slightly lighter than the photos, but it still matches our room decor nicely. Would recommend.

Perfect for our growing family

This extension bed is exactly what we needed. The solid wood feels very sturdy, and it was easy to attach to our existing window sill setup. My toddler loves having his own space right next to us.

Excellent value for solid wood

You rarely find real solid wood furniture at this price point. It's heavy, durable, and the adjustable height feature works perfectly with our different mattress thicknesses.

Sturdy and safe

I was worried about stability, but this bed does not wobble at all. The anti-tip brackets give me peace of mind. It looks beautiful in the nursery too.

Best investment for co-sleeping

We wanted a safe way to co-sleep without sharing the same mattress. This side crib attachment is perfect. The rounded corners are a great safety touch for active kids.

5 FAQ

Q: How long is the shipping process?

A: Orders are typically processed within 24 hours and delivered within 5-7 business days via standard ground shipping. Expedited options are available at checkout.

Q: Does this come with a mattress?

A: No, the mattress is sold separately. This frame is designed to fit standard crib or twin-sized mattresses depending on your configuration.

Q: What is the weight limit for an adult using this?

A: The bed is tested to safely hold up to 220 lbs, making it suitable for older children, teenagers, and most adults for occasional use or reading.

Q: Can this be used without attaching it to a window sill?

A: Yes, while it is designed as an attachment, it can also function as a standalone low sleeper bed if you choose not to secure it to a wall or sill, though we recommend anchoring it for maximum safety.

Q: Is the finish safe for teething babies?

A: Absolutely. We use only non-toxic, water-based lacquers that are free from lead and harmful chemicals, ensuring it is safe even if little ones chew on the rails.
