I am generally against storing things under your bed because I feel it creates bad bedroom energy, BUT I do find it necessary - at least a little bit - in NYC, so I've created and update this list each year. Following are the best storage beds that I know about, at a wide range of prices. If you are going to store, keep it organized, clean and as uncluttered as possible. And if you don't need to, good for you! But save this list for the day you need it ;-)....
>> Zanotta Night Bed by Carlo Columbo - Very Italian and clean with a similar hydraulic lift to Flou
>> Flou Beds - Flou specializes in beds and has 24 models with storage, including their signature hydraulic lift beds.
>> Matera Bed - Designed by Sean Yoo for DWR, this elegant frame is made of walnut and includes six vacuum-closing drawers.
>> Box Bed by Emaf Progetti - Another Italian confection with an even cleaner look from Unica Home
>> The Anderson Ultimate Bed - This is a niche killer on storage. Taking away the need for a dresser, the bed comes with so many options that allow you to fill the base with easy-pull drawers on both sides and on the end, as well as adding clip-on side tables.
>> Blu Dot Modulicious - These Minnesotans did an amazing job updating the "captain's bed" into a modern item.
>> Wonk Knickerbocker Storage Bed - Similar to Blu Dot, but a little beefier and woody, Wonk's Brooklyn design shop also offers a wide range of finish and hardware options here.
>> The Boxer Storage Bed - From England, this may be hard to get, but it's a really nice design.
>> Simple Maple Bed with Storage Drawers - If you like stripped down, simple and green, this is a great option. These Pacific Rim beds are VERY GOOD: "Each piece is hand-rubbed with a finish of tung oil and pure beeswax to highlight the natural beauty of this distinctive Maple hardwood. They are free of toxic glues, formaldehyde and particle board and considered environmentally safe for your children's bedroom and nursery."
>> Storage Bed from West Elm.
>> Bossa Bed from EQ3.
>> Locker Bed from PBTeen.
>> Harmonica Storage Bed from CB2.
>> MANDAL Bed with Storage from IKEA. This is your rock bottom value buy starting at $329.
>> DIY Platform Bed with Storage
