Review: Feels Stable, Good Quality - A little backstory: my husband and I had wanted to plan on doing a Montessori floor bed for our son when he was ready to transition to his own room, but realized that, for us, this may not happen for quite some time (and by that point we may just go straight to toddler bed). Our 11 week old son had recently outgrown his smaller bassinet, and in this transition has been sleeping in the bassinet insert in a pack n play in our room- but now that he is more active and wiggling and kicking all the time, the pack n play bassinet just does not feel stable (plus the “mattress” is really just more of a board which I can’t imagine would be comfy for sleeping). Just received the crib yesterday, and my husband set it up last night in our bedroom (our son will sleep in our room until at least 6 months, if not longer). As far as I know, it was relatively easy and straightforward to set up, although the longer front and back pieces weren’t labeled up from down so my husband just had to flip it around at one point to get all the edges along the top flush. Obviously have not had this crib long enough to comment on durability, but it feels extremely stable (which was my main worry when ordering a crib that was under $100). It does not wiggle at all, and all of the joints are completely tight together. I was worried about the hardware not being hidden like some of the more expensive crib models, but the ebony color we ordered came with dark charcoal/black hardware so it barely shows at all. Not sure that would have been the case with the hardware that comes with the other color options. We have the Newton Baby crib mattress (also highly recommend!) and it fits so perfectly in this crib- so snug down in the frame there’s not even a hair of space between the mattress and the slats. I didn’t really check the height of the crib before ordering, so was a little surprised with how low it seems overall- but I actually prefer that, since our son’s nursery is pretty small I think it will feel more size-appropriate for the space once we move it in there. Will update in the future if this changes, but so far, very happy we took the chance on this very affordable, cute little crib!
Review: Simple, easy to assemble, shorter than expected, but decent for the price - Update: 4/28/20 our daughter is going to be 3 in June and still happily sleeps in this crib (and she’s a solid kid, wears a size 3/4T already and over 35 lbs). It’s still as solid as it was the day we first put it together. Great buy! Updating review to 5 stars Original: We bought this crib for our 3rd daughter (after giving away the one we used for our other daughters). I wasn't looking for anything super high quality, as I am certain this will be our last child, and for $117 I don't think it's a bad buy by any means. But I'm not sure how well this will hold up to the wear/tear of a toddler when it's converted to a toddler bed knowing how my others daughter used to push on the sides of the cribs/climb all over it, etc. But I do think it'll do it's job as a crib for a small baby. One thing I wasn't quite expecting was how short the crib is. My 5 year old daughter is tall enough to see into the crib w/o having to look through the crib slats. This doesn't bother me though as I'm excited for my girls to be able to stare lovingly at their new baby sister :), but I wonder too how this will work to keep a baby in their crib when they are taller, standing and climbing around. Our previous crib was a DaVinci model that our daughters were never able to (or at least never tried to) climb out of, and they stayed in it as a crib for 2 years, then another year or so as a toddler bed. Bottom line: if you are looking for something smaller (probably same size as an Ikea crib), simple looking and not needing a crib that will last through more than one child this is a good buy.

### ⭐⭐⭐⭐⭐ Affordable and sturdy.
*by A***O on September 24, 2017*

This is a great crib for a great price. It came quickly and was well packaged. Instructions could have been a bit more clear but I figured it out after sleeping on it (it was rather late anyway but wanted to get it done). Comes in about 8 pieces and is quite easy to put together. Just be sure to place the end slats with the 4 mattress adjustments facing inward toward the long railing of the crib (facing each other) on each end. I had them facing the wrong way at first but figured it out and positioned them correctly. Great deal and love the look. Works well with my color scheme and love the simple modern look. I have a 1yr old and he bounces in it and I've even caught him diving from one side to the other and it is sturdy. He's safe there - and I don't have to worry about tipping either, I've tried tolippig it with my 200+lbs and it's just fine. No worries here for my 24lbs infant boy with his need for speed... (already lol). He can use it until he grows out and into the toddler conversion - which is sold separately for about $50-$60.
