What to know before buying

Listing details to confirm

The listing details are inconsistent: the title gives 40-inch and 48-inch versions and 450/550 lb capacities, while the selected model is named RT - 001 40inch and the details state a 40-inch frame size and 204.12 kg maximum weight recommendation. The stated overall dimensions also conflict between 102L x 152W x 102H centimetres and 102 x 152 x 102 cm, with the latter additionally listing 9.18 kg. Confirm the selected version, load limit and dimensions before buying. The feature text also claims a six-leg base and 8mm bungee cords, while the technical details list 28 springs and bungee cords, so the exact construction is not fully clear.
