I ordered one bed to make sure my dogs liked it and it took them a few days to warm up to it but now they love it and so we had to order another one. Now they each have their own and everyone is happy! I got one bed with the 40 oz. vinyl and the other with the ballistic nylon and they seem to strongly prefer the latter fabric but that might just be them. The smooth vinyl seems to make them a little nervous and the ballistic nylon has a little more 'give.' I would also recommend these beds to humans with allergies (which was one of the main attractions for me). They are much easier to clean, wash, vacuum under, and don't collect hair the way tradition soft beds do. The Springer is on a medium bed and the lab mix is on a large bed, both with the deluxe fleece pad.
