OK,but what if OP doesn't have money to purchase another hardware wallet or he goes to a country,where hardware wallets are not sold?
You'll have two options. The first is to purchase another hardware wallet and restore your seeds using it. The second is to download one of the popular wallets out there and restore it. Most of the hardware wallets generate BIP39 seeds, but you'll still have to know the derivation path for your specific wallet. It shouldn't be a problem because that is public information.
If you used a hardware wallet to store your Bitcoins, it would be far more advisable for you to just restore it to another hardware wallet to maintain the security. If not, then I believe I've already stated that you don't necessarily need a hardware wallet.
