  • Size:

    When it comes to mattresses, one size definitely doesn’t fit all. The mattress should be longer than the tallest person sleeping on it. The bed width should allow enough space to fold your arms behind your head without going beyond the mattress edge or touching your partner’s elbows (for two adults, we recommend either a queen or a king).

Overview & Specs

Sealy Posturepedic Caversham 10.5" Firm Mattress
Every Sealy Posturepedic mattress is engineered to fully support your back and align your body so you get a comfortable night’s sleep. The Caversham Firm Mattress delivers all-over support, with the comfort you need and deserve. It features a specially engineered encased coil system that responds to the natural curves and alignment of your spine. The encasing allows each coil to move independently, for more targeted support. This helps to reduce motion transfer that can wake you when your partner moves. This mattress has all the features and comfort you will need for more relaxing sleep.
