WillIVAR Shelving unit, pine, 35x11 3/4x70 1/2 "fit in aRenault Captur 2024?

The Captur gives you a compact, upright boot rather than a long one. Behind the rear seats the floor runs about 26 3/8 inches, so tall or square boxes load fine but anything long sits at an angle. The opening is 37 inches wide and 32 1/4 inches tall, and there is a 7 7/8 inch drop from the sill down to the floor, so you lift over a lip then set down. Fold the rear bench and the floor stretches to 56 3/4 inches, a gain of 30 3/8 inches that changes what the car can take. Slide long boxes in low and straight down the 40 1/8 inch centre channel.

The IVAR shelving unit packs into one long, slim box: 70 1/2 inches long, 3 1/2 inches wide, and just 1 3/4 inches thick. At 6 lb 1 oz it is light, so the problem is never the weight, it is the length. That 70 1/2 inches of rigid pine will not bend around a wheel arch or a seat back, so a short boot forces it across the cabin at an angle. An estate or a hatchback with the rear seats down takes it easily. Load it flat and straight, thin edge up, and rest the far end against a seat back so it cannot slide when you brake.
