The mistake is buying one for the storage and forgetting you still have to lift a mattress and a divan lid every time you want to get at it. Storage beds are sold on the promise of hiding away the off season duvets and the suitcase nobody can find room for, and that's real, but only if the mechanism underneath is actually good. A lot of them are not.
Before you buy, get the lid or drawers open in the shop and keep them open. Check the hinges on an ottoman style base: are they gas struts that hold the lid up on their own, or is there a flimsy little arm that lets it slam down on your fingers the second you stop paying attention. If it's drawers, pull them all the way out and look at the runners, because cheap plastic glides will drop and stick within a year under any real weight. On delivery day, check the base is actually flat and supported underneath, not just a frame with hope in the middle, since a sagging base will wreck a mattress faster than anything else in the house.
These earn their keep most in smaller bedrooms, box rooms, studio apartments, anywhere you don't have a spare closet or an attic to send the winter bedding to. They're also good in family houses with kids who generate an unreasonable volume of soft toys and off season clothes. In a big house with a proper dressing room, a storage bed is mostly dead weight you're paying for and never opening.
The difference between a good one and a bad one usually comes down to the base frame and the lifting mechanism, not the headboard. A solid, properly braced frame underneath, real metal hinges or struts rated for the lid's weight, and drawers running on metal ball bearing runners rather than plastic, that's what keeps the thing working in year three instead of year one. Veneer on the visible panels is fine. Flex or creak in the base when you sit on the edge is not.
Over time the mechanism tells you everything. A good gas strut lid will still lift smoothly years in, a bad one gets slower and heavier until you're basically doing a deadlift to get your winter coat out. Drawers wear in the same way, smooth glides stay smooth, cheap ones start catching and need a shove. Wipe spills off the base fabric or finish quickly, keep the storage space itself dry so nothing mildews in there over a damp winter, and don't overload drawers past what the runners are rated for.
If I only had room to put one of these in a single room, it's the smallest bedroom in the house, every time.
