About the Sleepy's by Sealy Spring Stella Medium Innerspring Mattress

The Spring Stella is a value-priced innerspring mattress from Sleepy's by Sealy with a medium feel. Gel-infused foam cushions pressure points over a 5-zone individually wrapped coil unit that targets support and limits motion transfer. A stretch knit cool-to-touch cover and adjustable base compatibility round it out. It suits shoppers who want a traditional quilted hybrid feel without paying for premium materials, though some owners report feeling coils and a firmer-than-expected surface.

Questions and answers

Is the Spring Stella good for side sleepers?
It is rated for side, back and stomach sleepers with a medium feel. The gel foam cushions pressure points, though side sleepers who want deep cushioning may find it firm.
Does it work with an adjustable base?
Yes. It is adjustable base compatible, so it can be used on a power base.
How firm is medium comfort?
It is a balanced medium: supportive enough for back and stomach sleepers and cushioned for side sleepers. Some owners describe it as firmer than expected.
Will I feel motion transfer?
The individually wrapped coils are designed to limit motion transfer, so a partner's movement is less noticeable than on a traditional open-coil mattress.
Does the cover sleep cool?
It has a stretch knit cool-to-touch cover meant to help regulate temperature. It is not an active cooling system.
What is inside the mattress?
Gel-infused comfort foams over a 5-zone individually wrapped coil unit, finished with a quilted stretch knit cover.
