We are in love with this bed after months and months of searching for the perfect bunk bed. The quality is superior the only thing I noticed so far is on the slide my son will throw toys down and it left some marks already. But I’m sure that can happen to any bed. I love that the slide and ladder is hooked on so can be removed anytime. Manufacture recommends 5” mattress but can accommodate up to 9”. We chose 8” memory foam mattress. Anything less than that the mattress will be firmer.  The down side of choosing a mattress more than 5” is the height between the lower bunk and upper bunk is smaller now so adults can sit on the bottom bunk without slouching. So just something to consider. It’s a low bunk bed making it slightly safer for the kids which is my favorite part of the bed. Price is great considering it comes with a removal slide and great quality. Highly recommend.
