About the Kia Niro 2023 boot

The Kia Niro 2023 opens wide at 41⅜″ across and 31⅞″ tall, so squeezing a box through the mouth is rarely what stops you. The limit is floor depth. With the rear seats up you get 32⅝″, tight for long boxes, but drop the bench and it stretches to 65⅜″, a gain of 32⅝″. The floor holds 41⅜″ across at its narrowest, so flat packages sit side by side. The load lip is high at 29⅛″ with a 5⅞″ drop to the floor, so lift over the sill, then slide long flat loads in with the seats folded.

About the VÅGSTRANDA Pocket spring mattress, medium firm/white, Full package

The Full size VÅGSTRANDA ships as one roll-packed package, 58¾″ × 18¼″ × 17¼″, so the challenge is bulk rather than length: a dense bundle weighing 90 lb 3 oz. Under 59″ long, it fits across most folded rear seats and into most SUV cargo areas, but it does not squeeze: the 17¼″ thickness is firm and gives almost nothing. Two people make loading far easier than one, and a blanket underneath protects the wrap from tears. Once home, give it space when you cut it open: a roll-packed mattress expands quickly and with force.
