Twin Extra Long Size Memory Foam Mattresses
Soft and highly adaptable, memory foam mattress technology began with NASA using viscoelastic foam for airplane seats. Manufacturers also used this technology in helmets and shoes before finding the perfect commercial application: mattresses. A memory foam bed provides support and comfort, as well as lower motion transfer than innerspring mattresses because there are no coils shifting when your partner moves during sleep. Check out the memory foam mattress selection available, including many memory foam bed options on sale.
