Lay-Z-Spa (Bestway)Lay-Z-Spa Helsinki AirJet

The Helsinki is the pick for regular larger gatherings and for anyone who finds standard inflatable walls too soft. Its rigid drop-stitch construction is firm enough to perch on the edge of and tends to feel sturdier and last better than the I-beam laminated walls used by most inflatables, and it wraps that in a wood-print finish. WhatSpa rates it their overall best inflatable, citing a seven-person, roughly 1,123L body, patented Freeze Shield, rapid heating of around 1.5-2.0°C per hour and a two-year shell warranty. It seats one more than the Paris and feels more solid, but costs about £260 more and is bigger to house and heat, and it is still AirJet-only - so despite the premium size and price there's no targeted water-jet massage. We rank it below the Santorini because that tub adds real water jets and WiFi for the money, but the Helsinki is the better buy if capacity and build matter more than hydro-massage.
