Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Queen fit in a Skoda Octavia Combi 2025?

The Octavia Combi's tailgate opens 40½″ wide above a 25¼″ loading sill. The floor sits just 3⅞″ below that sill, so boxes slide in almost level. There is 42⅞″ of floor with the rear seats up, and folding them adds 30⅜″, for 73¼″. At its narrowest the floor is 39⅜″ wide. On the way in, every box has to pass under 26¾″ of clear height over the sill, while the boot is 30¾″ tall from its floor. Some boxes longer than 42⅞″ still fit with the seats up, at an angle and on their side. Load the longest box first, then fit the rest around it.

The Queen VÅGSTRANDA mattress weighs 111 lb 14 oz, all in one box of 66¾″ × 17¾″ × 17¼″. Its ends are nearly square, so there is nothing to hook your fingers on: it is a long, heavy block that you carry from underneath. Inside the boot, the box takes 66¾″ of floor lying straight, 17¾″ across and 17¼″ of height. Move it to the car on a flat trolley, so the only lift is the last short one into the boot, and make that lift with two people, together on a count.
