Ratings & Reviews+

South Shore Cosmos Collection Twin Size Black Onyx and Charcoal Mates Bed is rated 4.1 out of 5 by 197.
Rated 4 out of 5 by from Beautiful Twin Bed for a growing child:) Me and my husband recently purchased two of these beds for our twin daughters. When we picked up the beds the come in a long, large box, so make sure you have a van or large SUV when picking up the package if you choose to do so. The instructions were easy to follow and the packaging of the parts help when figuring out what goes where. The overall product when complete was two beautiful twin beds. The drawers on the bottom can be tricky to install but when complete offer great storage, since they are rather roomy.

Rated 1 out of 5 by from poor quality The beds are a fake wood grain of black and gray. I bought 2 beds. One bed was never received because it was broken during delivery. The second bed also had broken parts. The bed is made of particle board. It did not seem that the bed would withstand much weight.

Rated 1 out of 5 by from Arrived in damaged box and not usable When I picked up my delivered platform bed in a box, the end was crunched and exposed to the air. I noticed when I took it out that it was chipped off on an end but thought I could make it work and went on to attempt to assemble the bed. Upon assembly I realized that the broken corner meant that the bed would not brace at the base, and would remain unstable in use and for the drawer to go in and out. I am returning this product after much time and effort. Don't except if the box is damaged, and do not attempt to assemble alone and if you are not handy with projects. The directions are awful, no written directions, just pictures! It is impossible to decipher which length of screws go in to which area from the tiny pictures. If you are very handy and don't need directions, and there is no damage to the box, it could be a cute bed, but would not stand up to a move.

Rated 5 out of 5 by from Awesome I was a bit hesitant to order this bed because it looks brown in the picture and I wanted black but after opening the package I was extremely relieved to see that the bed actually is black. I'm not sure why they make it look brown in the picture. It took me and my mom about 3 hours to put both the bed and the matching headboard together but MAN it looks sharp. It's sturdy and modern looking. I love it!

Rated 4 out of 5 by from Bought this for my son for college - along with the dresser and desk. Overall pretty happy. Took a while to put together - but not too long. Used some glue also. Pretty idiot proof - since the directions were jsut ok...but not bad. Nice to have the extra storage space. The drawers are solid - but the bottom is a fiberboard - so I wouldn't over stuff them. Handles are metal.

Rated 4 out of 5 by from Great for younger child I was glad when I received this and it did turn out to be black, which is what I wanted. The picture looks dark brown to me. My husband put it together without too much difficulty, just a little time consuming. The mattress we have (twin) appears to be too small for the bed and there is a small gap that runs all the way around it. The drawers are great! Lots of space! I am a little concerned about stability. It's for our 11 yo son, who hasn't come home from the summer away. My husband layed on it for a minute (he's 6' 200 lbs) and said it seemed sturdy to him, but I wasn't going to do it myself (I'm currently pregnant and was just afraid I was going to break it, lol). Overall though, it looks great and I am pleased with it. I think my son will be too.
