Sealy Perfection Plush Mattress

Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.

Choose this one if you want a medium feel that suits most sleeping positions, with foam layers for cushioning over a springier open coil base rather than an all-foam feel. The Unicased edge support is a genuine plus for couples or anyone who sits on the edge of the bed to get dressed, as it stops the sides collapsing. The temperature regulating technology should help if you tend to run warm, although the listing gives little detail on how it works. The 60-night trial from Mattressman does at least give you a way to test it at home, provided you buy from that retailer.

Combination sleepers
The medium feel is described as suiting most sleeping positions, so changing between your back, side and front through the night should feel comfortable.

Warm sleepers
Temperature regulating technology is mentioned in the listing, which should help if you tend to run warm, though the detail on how it works is thin.

Back sleepers
Foam layers sit over a springier open coil base, giving cushioning with some bounce, which suits a medium feel for lying on your back.

Side sleepers
Foam cushioning layers on top of the coil base give a medium feel that suits lying on your side, without the sink of an all-foam bed.

If you prefer a distinctly firm or distinctly soft mattress, this medium feel may fall between two stools. If you prefer pocket springs, you should note this uses an open coil system, which moves more as a unit, so partners who are easily disturbed by movement may want to look elsewhere. It is also a considerable spend if budget is tight.

Is the Sealy Perfection Plush soft or firm?

It is listed as medium, which suits most sleepers, although lightweight side sleepers may find it slightly firmer than expected and heavier back sleepers may want more support. A medium feel is generally a safe middle ground if you share the bed with someone who sleeps in a different position.

Does the Sealy Perfection Plush come with a trial period?

Mattressman lists a 60-night trial with this mattress. That trial is Mattressman's own offer rather than a Sealy guarantee, so if you buy from a different retailer the terms may differ. Always check the returns policy of wherever you order from before committing.

What sizes does the Sealy Perfection Plush come in?

It is available in UK Single, Double, King and Super King.

How quickly can the Sealy Perfection Plush be delivered?

Mattressman offers free next day delivery on this mattress, with a handling time of 0 to 1 day and transit time of 1 to 3 days. These are the retailer's delivery terms, so timings may vary if you buy elsewhere.

Does the Sealy Perfection Plush have good edge support?

Yes, it features Sealy's Unicased edge support, which reinforces the perimeter of the mattress. In practice that means the sides feel more stable when you sit on them and you can sleep closer to the edge, effectively giving you more usable surface.
