⚠️ Pre-Purchase Compatibility & Quantity Guide

Please verify each step below before selecting a variant.

Step 1 — Confirm Your Bed Model Year (360 Incompatibility)

AIRPRO air chambers are compatible with classic dual-hose Sleep Number® pump systems (most models made before 2016) as well as compatible with Sleep Number 360® smart beds, which use an internal pump and external hose fittings. To check: if your pump has two external hose ports — one per side — you have a compatible system. If you have a four hose system - two per side - call (314) 599-2777

Step 2 — Identify Single vs. Dual Configuration

• Twin XL & Full beds: Typically use a single chamber per bed — order 1 chamber.
• Queen, King, and California King beds: Use a split/dual configuration — each side is a separate chamber. Order 2 chambers if replacing both sides, or 1 if replacing only one side.

Step 3 — Measure Your Current Chamber

Remove the old chamber and measure it flat (deflated): width × length. Match your measurement to the variant dimensions listed in the selector below. All dimensions are in inches.

• Twin XL: 30 × 72
• Half Queen Dual (per side): 26 × 72
• Half King Dual (per side): 34 × 72
• Half California King Dual (per side): 32 × 76
• Queen Single: 52 × 72
• Full: 46 × 68

Step 4 — Verify Hose / Nozzle Location

AIRPRO chambers have the air nozzle located at the foot end of the chamber. Confirm this matches the hose entry point in your bed foundation before ordering.

Step 5 — Pre-Purchase Confirmation

Before adding to cart, confirm all of the following:

• ✅ My bed is not a Sleep Number 360® model
• ✅ My pump has two external hose fittings (one per side)
• ✅ My measured chamber dimensions match the selected variant
• ✅ I know whether I need 1 or 2 chambers for my bed size
• ✅ The hose connects at the head of my bed, If it connects at the hips or foot, you will need extension hoses
