The big one.

Eight feet across, four built-in backrests, and reinforced air chambers that keep the whole platform steady when everyone shifts at once. This is the island you buy when the pool party is a standing arrangement, not a one-off.

Every seat has its own backrest, so nobody's stuck propping themselves up on an elbow. The heavier construction is built to go in and out of the water all season without babying it.

• Four built-in inflatable backrests — a proper seat for every person

• Reinforced air chambers for stability when people climb on and shift around

• 8' × 8' — the largest island in the Aqua Luxe lineup

• Heavy-duty construction made for season-long use

Best for: groups of four, socializing in the pool, season-long use

Note: measure your pool before ordering — 8' × 8' is a serious footprint in a smaller above-ground.

Pro tip: Inflate each chamber firm but not rigid. A little give in the seats and backrests is the difference between an hour on the water and all afternoon. Let the air out fully before folding for storage.
