Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Twin fit in a Kia Sportage 2023?

The Sportage boot is wide and loads dead flat. The opening is 41⅜″ wide × 28¾″ tall, and the floor runs 35⅜″ with the seats up, reaching 66½″ folded, a gain of 31⅛″. At its narrowest the floor still measures 41″, so wide boxes go straight in without angling. The sill is 28⅜″ with a 0″ drop, so the floor sits level with the lip and items slide in without lifting. The opening is a touch low, so watch tall boxes through the gap. It is strong for wide and long loads, fold the seats for the longest flat-packs. Slide items along the flat floor rather than stacking high.

The VÅGSTRANDA Twin arrives roll-packed as a single dense block, 43¾″ × 18¼″ × 17½″, weighing 69 lb 4 oz. The shape is friendly, the weight is not: it is a compressed pocket spring mattress, so all of that mass sits in a stubby bundle with no handles and a wrap that likes to slip. Because its longest edge is 43¾″, most hatchbacks swallow it with a seat folded, and many boots take it outright. Carry it with two people, load it on its long side, and leave the wrapping sealed until it is in the bedroom: once it unrolls, it never goes back.
