Depends on your definition of "seamless".
The base standard's behavior requires a reassociation to the new cell (i.e. AP i.e. BSSID). This introduces a gap in coverage, but for simple setups like the 5-AP one IgorPortola is talking - I assumed that this was using shared-password auth - the gap's length is functionally 0. 802.11r gets rid of that gap, which is important when using heavier-weight authentication protocols like 802.1x.
(Note that by 802.x in my original I meant not 802.1x, but rather the set of standards including 802.3 (ethernet) and 802.11 (wifi))
